Five problems related to electrical system have been reported for the 2000 Jeep Wrangler. The most recently reported issues are listed below.
While driving down the road, speed doesn't matter bc it has happened at multiple speeds, the speedometer and tachometer will drop to nothing, while the other gauges like gas, oil pressure, temperature and such do not have any issues and remain where they should be! a few seconds after the speedometer and tachometer drop, the engine light comes on and the odometer will read �no bus�, a few seconds to a minute later the gauges will resume and the engine light and �no bus� disappear! another example of this is the speedometer and tachometer will drop and other gauges not be affected like previous scenario only with this one the airbag light will illuminate, lasts for a brief period and then goes back to normal! it happens sporadically, but have noticed it happens more on bumpy roads! none of this has happened while the vehicle is stationary at idle! all while driving down the road, various speeds, various types of roadways!.
Over heating of a/c - heater control switch while in use caused the switch connector, switch and part of the hvac control panel to melt. On the verge of fire the fan stopped functioning. Retrieved the same unit off a doner vehicle [1j4fa59s3yp733181] and found the control to be melted/burnt in the same fashion. When I looked for a replacement, the parts suppliers offered a ready-made replacement wire harness [potential clue of common failure]. The mopar replacement part is listed as discontinued. I have taken photos of the issues described, but will have to get them developed and digitized [my digital camera won't take close-up pics].
The pcm/ecu (cars computer or brain), that controls everything in the vehicle, sensors, emissions, fuel etc. Has gone out for the second time causing a crank no start issue. Took vehicle to my local Jeep dealer (hemet, CA. ) for them to charge me $1450. 00!!! for a new pcm! and not a new part, but a rebuilt one! I can find factory replacement pcm's online for $520. 00 new not rebuilt! have read numerous owner CO mplaints about this very same part and wondered, "why no recall or TSB"? thank you for any help.
Mode selector for the hvac system has a major issue melting the selector, harness and control module. After researching this incident online and to my surprise there is no recall on this subject. Heater not working, possible heater system catching on fire do hi voltage to the mode selector witch causes entire hvac failure and possible fire. Jeep has known about this for a while but no one seems to be getting on them about it. Again 2000 Jeep Wrangler heater control failure.
The consumer smelled led burning/ plastic prior to stoppin, the fire originated in the power distribution box. Claim number 17-9135-135.
