Failure Date: 05/01/2008

The contact owns a 2006 Jeep Wrangler. The vehicle is a right hand ride Jeep. At 9,000 miles, the contact had to replace the heating switches and wiring harness. She took the vehicle to the dealer and they dismantled the dashboard. They noticed several malfunctions and replaced a number of wiring harnesses in order to repair the heating switches. Recently, the vehicle had to be returned to the dealer due to alternator failure. The alternator sent so much heat to the battery that is caused the water to boil. Sulfuric acid spilled all over the firewall of the vehicle. The contact was informed that the alternator was sending currents of up to 19 volts to the battery. The failure mileage was 56,000. Updated 05/21/08 the consumer stated he replaced the heater switch 3 times, the alternator and starter were replaced as well. The defroster was inoperative. Updated 05/20/08.

When driving my 2007 Jeep, it has 2x, completely shut off while going about 70 mph in traffic. I took it to bondy's Jeep dothan, looked at by service depart. And given back - nothing wrong. The second time, returned to bondy's, some wiring harnesses were replaced. Then recall was issued, took it back-they fixed recall. Continued to have issues, been to bondy's eight times. It has not shut completely off again that was pretty scary - but the dashboard lights up with errors and I lose power everything (air conditioner, signals, radio, entire control panel, etc?). The same thing happened when it shut off completely, so my concern is that it will happen again. If I were to pull out onto a highway, that could be it. Please advise me on what action I need to take. Following is a timeline of what has been going on. I have not been able to get anyone from Jeep to call me to help me with this issue. I have only been working third party with my local Jeep dealer, who has been great, but has not yet solved any issues. 4/14/2007 Jeep cuts completely off while going 70 mph on hwy 431 all cluster lights lit up. 4/15/2007 Jeep cuts off completely again pulling out of the grocery store parking lot. 4/17/2007 took it to bondy's. Got it back on 4/19/2007. Service dept stated it was fixed. 4/26/2007 all clusters lit up like before but did not shut off. No air conditioner, radio, nothing electric worked. Took to bondy's. 7/11/2007 same thing 7/12/2007 recall received by mail, took to bondy's. 8/2/2007 it happened again. 8/3/2007 took to bondy's left it with the service dept. Do not have it back yet. It has been at bondy's 39 days total since time of purchase, in the service dept.

Noticed a burning smell and thought it was one of four trucks ahead of me. Pulled off onto my exit and continued to notice the smell. Smoke began pouring from the dash. I had seen the service department the same morning and informed them my blower motor had been working intermittently. They verified the problem and ordered a new motor. Upon inspection of my vehicle I notice that the area around the blower motor is extremely hot. Blower motor has the following: label 1 valeo:kjlhd 929520g rev a -- pass 11-18-4 10:10:50 label 2 bosch made in mexico dpl 653 12v 9 000 025 075 19 904 929431h cw 49104 1.

: the contact stated while driving over bumps the odometer and speedometer fail. The airbag warning light illuminates when the needles drop. The problems occur at various speeds. Upon inspection the dealership determined the wiring harness needs to be replaced. There is a NHTSA recall, # 99v117000, regarding the instrument panel wiring. The vehicle has the same problems as indicated in the recall; however it is not included in the recall due to the VIN.

Failure Date: 02/01/2006

Blower controls/resistor pack short out, fail and cause wiring harness to melt for the hvac blower and blower controls. Blower wiring harness appears to pull the full current of the blower motor through the whole switch controls wiring harness, this causes an overload condition and overheats the wiring of the control system, causing severe melting of the plastic components and poses a severe fire risk.

1st issue: the dash gauges will go off and on intermittently. I have fought with this problem for years now. The dealer of course doesn't know what I'm talking about. Never heard of it. I have completely removed the dash looking for problems. Bad grounds? I can't tell where. I suspect the plugs the cluster slips into. I've tried to pull the mounts closer for a better connection. It seamed to work for a while. Then it comes back. A good sound beating on the dash brings them back on. Amazing what that plastic will take. All this started after the warranty expired. I refuse to take it in and pour money at it till they figure it out. All I want is to know how to fix the gauges. I'm about ready to cut the wires and solder them directly on. 2nd issue: I began smelling plastic burning or something. Later the heater fan quit working. After some reading of the service manual, I checked a lot of parts and found the control/selector switch unit heated up and partially melted the wire plugging into it as well as burnt inside the unit. Bought another and replaced it. Works great now. All the fan positions work again.

1999 Jeep Wrangler sahara with air conditioning - hvac electrical issue: smelled burning/melting plastic, then hvac controls quit working. I disassembled the dash to find the electrical connector on passenger side of hvac controls had melted. Looks like it could lead to short-circuits or fire.

Failure Date: 02/02/2005

I have had this problem 3 times with my vehicle now. The vehicle was having heater problems on highest and second highest speeds. Took the Jeep to the dealership and paid deductable on the service contract in October 2002. Dealer replaced the under dash harness, blower motor and the blower motor resistor. I continued to have problems and took it to my personal mechanic that discovered that the heater control module had failled as well. He replaced the heater control module and Jeep worked fine for 1 year. The heater began to have the same problems again and my personal mechanic replaced the blower motor, blower motor resistor and the heater control unit as well as replacing a burnt wire. The heater again lasted just over a year before actually catching fire under the dash. The entire under dash harness, blower motor, blower motor resistor and heater control unit were again replaced. No additional problems within the past week after receiving the Jeep from the shop.

Failure Date: 01/10/2005

Normal use of fan speed control switch of 1999 Jeep Wrangler. The male tabs on back of switch break causing shorts and failure. Replaced under warranty twice. The second time was in new york on vacation and the short caused a dash fire in which the wiring harness had to be replaced. Luckily nobody was hurt due to close proximaty of dealership. Replaced a third time myself due to rejection by dealer and Chrysler to cover cost. There has been at least three and maybe four switches since purchasing this vehicle new. This issue has been ongoing almost immediately after purchase. Chrysler dealerships in wilmington, nc and geneva, NY where fire occured kept old parts. All parts replaced brand new and still continue to fail. My fear is the switch will continue to fail and cause further fires and possibly loss of vehicle or personal injury. With the trouble I am having, I find it hard to believe there is not a more wide spread issue.

Failure Date: 11/22/2004

The air bag light appeared on the dashboard and remained on. The interior gauges for the dashboard lights appeared on and remained on as well. The gasoline gauge and the speedometer were inoperable. This caused poor visibility to the driver. The consumer drove to the dealer and after inspecting the vehicle, the mechanic informed the consumer that the dashboard panel needed to be replaced and the clock spring for the air bag. Please provide additional information.

Vehicle was experiencing an erratic instrument cluster, and air bag light operation. Intermittently while driving instrument cluster, speedometer and tachometer rolled back to zero, and the air bag warning light came on. Also, at 82,000 miles left turn signal engaged when the brake pedal was depressed, and at 78,000 miles when driver's side door was opened while the truck was still running the defroster light came on. Dealership had not been contacted. Consumer took vehicle to two Jeep dealers and said that they're aware of the problem and many customers have experienced the same problem. Also, they said that it was a defective electrical connector.

While driving at any speed operating instruments on the dashboard do not work. Also, air bag warning light stays on all the time, and speedometer is inoperable. Manufacturer and dealer had been informed of the problem. While this condition persist the odometer does not record mileage and the air bags may be inoperative in a crash.

1998 Jeep Wrangler, 4. 0l. These two issues are on service bulletins, but should be recalls. The first issue occurred as my wife was driving when the valve springs snapped, stopping the car in the middle of the interstate. Discussed in detail on service bulletin 182298, initially issued before I even purchased my car. It was very frustrating to find out that Jeep was aware of such a dangerous issue and did nothing to prevent such failures from occurring. The second is a very widespread and documented problem when the main instrument cluster spontaneously stops working, including the speedometer, odometer, air bag indicator, fuel gage, oil gage, etc. . . Discussed on service bulletins, 081599 I believe. You cannot tell your speed, how much gas you have, etc. . . Another implication is that the odometer is incorrect on many Jeeps.

The airconditioner switch has melted 2 times since I have owner this Jeep. Dealer says nothing is wrong. No add on equipment of any kind is present other than a cell phone charger in the cigar lighter receptacle. There had been no fire yet. . . But the wires are getting hard and brittle. The first switch just showed some melting of the plastic on the switch housing. The second switch had the metal lug that the high-speed fan wire connets to completely loose from the switch and hanging in the wire connector. I have been to 2 dealers and both said nothing was wrong. . . I must have just gotten a "bad" switch. But they still charge me about 80 dollars for a new switch panel each time.

Apparently Jeep Wranglers are known for this problem, yet there has never been a recall. For several months now my dash cluster has been malfunctioning. The rpm guage and speedometer both drop to zero, the airbag and check engine lights come on, and the digital odometer loses its readout and instead says "no bus". It happens sporadically, not continuously. I took it to an independent auto shop which was able to correct the problem, but it began again after a couple months. I just took it to my local Jeep dealer for this problem, as well as other electrical problems. (my Jeep wouldn't start for the last 3 days. ) they found a wire that was corroded and replaced or repaired it. My Jeep runs again, but on the way home from the dealership the dash cluster went haywire again. Everyone I have spoken to in the auto shops is aware that this is a common problem with Jeeps, including my Jeep dealer, but nobody has taken steps to remedy this problem. To date, I have spent nearly $1,300. 00 to fix the dash cluster and other electrical problems (probably all related) and my car only has 43,000 miles on it. Conveniently, my manufacturer's warranty expired at 36,000 miles. This began at around 38,000 miles.

My 1999 Jeep lost all gauges and the air bag light came on. I found out that Jeep has a TSB #08-15-99 since may 21 1999 because of a faulty connector. Since this is a safety problem I believe they should pay for the repair. Thank you.

Periodically the dashboard gauges cut out and do not function. At the same time the air bag light goes on. Per discussion with a dealer, if the airbag light is on the airbag will not properly function.

Wiring harness for dash, both hazard-blinker-headlights, burning plastic smell, could not locate, ended with smoke rolling out of steering column when when we started the engine, luckily, we pulled the fuse that powered it out of fuse box to enable us to return home--70 miles away, with no lights, blinkers, etc. Called dealer, wanted $400. 00+ to look at it, and asked about the erratic dash odometer activity. We took it to a local repair shop, and was told that it would have damaged the complete electrical system in dash had we not removed the power to the harness. Melted harness nearly completely. Erratic gauge operation still a problem, if you hit a bump they come back on. They still want 400+ dollars to look at it at the dealer. This is only one of many problems (converter replaced by dealer 2 times already in 1 and half year, brakes don't engage properly-had brake lines checked repeatedly, etc). Ts.
