Cooling Fan Problems of Chevrolet Trailblazer - part 2

Own 2002 chevy Trailblazer which I purchased used in may 2004 with approx. 35-37,000 miles on it. Driven on highway 5 days a week 61 miles round trip to work. Vehicle developed loud roaring noise, poor acceleration, increased gas usage within the last year which initially was occasional but as of yesterday became non-stop. Service engine light came on. Nearly hit from behind due to inability to accelerate when merging into traffic. Diagnostic code po495 which ended up being fan clutch. Part at parts store was 217. 99 w/tax. Afraid to take to dealership as multiple other owners with same problems paid $600+ for repairs with majority being labor. Frequency of fan clutch problems by other owners makes it apparent it should have been a recall by gm.

2002 chevy Trailblazer has a serious fan clutch problem. Vehicle has 52,000 miles. The clutch fan stays engaged at any speed, vehicle will suddenly loose acceleration and also gets poor gas mileage. Check engine light eventually came on about 2 weeks after the vehicle stated to sound like a tank. Will take this to a local mechanic as based off of the amount of complaints on the web with other people having the same problem, and the dealer charging $700. 00 to repair when the part can actually be purchased locally for $229. 00. There are definite problems with this and based off of all the other complaints gm is well aware that there is a problem, and will do nothing about it.

Engine warning light flashes occasionally. This has been happening with this particular vehicle since I purchased the vehicle. Repeated visits to the local dealerships have resulted in no repair. The vehicle experienced total engine failure to which the dealership stated it was a cooling fan. Even upon replacing this fan, the light continues to flash on/off. At one point the light stayed on to which onstar reported an engine cooling/ac issue. This warning was reported to the dealership, they stated the problem was fixed but the light will continue to flash every couple of days. This is abnormal and has been addressed multiple times but nothing has been done to fix the issue.

Fan clutch totally failed. No prior warning, fan clutch failed causing the Trailblazer to lose ability to gain speed/power.

Fan clutch failure on my 2003 chevy Trailblazer car "roars" as the fan does not disengage and experience loss of acceleration.

The fan clutch on my '02 Trailblazer is starting to go bad, with engine roaring at intermittent times, per the dealer, who refuses to warranty it, even the vehicle has less than 17k on it. It is out of warranty by 8 or so months. Gm has sent the wrong message. Called chevy, their ears are closed although they offered a maintenance deal if I would say I am satisfied. Such a deal since their service prices are sky-high. Unacceptable.

My 2002 Trailblazer with 70,000 (just outside of warranty) has a bad fan clutch. The dealer is trying to charge me $500 for a part that costs $230 at multiple local parts stores. My complaint, however, stems from the fact that a 5 minute internet search yielded 8 other Trailblazer owners who have had this exact problem. All 8 of the cars has less than 80,000 miles. This is obviously a problem that gm needs to react to and issue an optional recall.

Engine fan noisy. . . Runs too fast/high. A couple mechanics have said fan clutch is the problem and needs to be replaced. Transmission doesn't seem to shift smoothly. . . And seems to be related to this engine fan speed.

Thermostatic-controlled clutch on radiator cooling fan was not disengaging and "service engine soon" warning lamp was lighted. "on-star" service probe confirmed problem in power train/cooling system. Dealer confirmed defective cooling fan clutch and replaced fan clutch assembly. This is a SUV that rarely sees travel off of paved roads. All service performed at dealership. Cooling fan clutch should not be failing at 57,520 miles. "goodwill warranty" covered most of repair expense.

1) since owning my 2002 Chevrolet Trailblazer, on occasion, the car would drive and sound like a semi (loud and heavy when I accelerated). 2) July 19, 2005, with 51000+ miles, the SUV continually was loud and heavy when I accelerated. Finally, the engine light came on. 3) I took it to a shop and the mechanic said it was the electric fan clutch and he had seen it brake down in several Trailblazers. Cost to replace: $732. 33. I still have the old part if you need it.

4 w/dr light goes to 4hi/ all wheel dr/4 low without warning at anytime. The computer mode was replaced once under warranty at the moment it doesn't seem to be actually shifting. Also had a loud jet sound coming from the engine as if it was laboring and had to have the fan clutch assembly replaced @ a cost of over $800. 00 .

Engine cooling fan clutch stuck engaged, causing engine service light to come on. Dealer(moritz chevy) charged $725 for repair of which $400 was labor.

Fan clutch failed at 49,000 miles after intermittent roaring sound almost from date of new purchase 6-20-02. Required replacing at my $600 cost.

Fan clutch failed in near full on mode causing excessive air flow when during winter season. After approximately 20 miles highway travel attempting to return from a vacation the "service engine soon" indicator illuminated. Readout of this error was p0495 fan speed high.

This vehicle was purchased new in Jun 2003. While still under warranty, various recalls were issued for steering, brake lights and rear hatch locking/handle assembly. Since then, the vehicle has been a lemon. Power steering pump replaced twice (first one I paid for, second independent and very reliable mechanic shop paid). Next the engine cooling fan bearing had to be replaced. Later, the transmission had to be rebuilt. I also had to get the computer checked and reset to avoid surging engine rpm and resultant speed deviations. Reaching a point of frustration as never before, I wrote gm asking for consideration repairing the transmission and received no response. I know they received the email since I had a "receipt requested" feature activated in my office computer. I sent a second email stating I was aware of the email receipt and that I expected a response. No such luck. All these problems manifested themselves well before the 100,000 miles were reached. Now at approximately 132,000 miles, I had to replace the exhaust manifold due to a crack, the vehicle has lost power on two occasions, the entire dashboard has gone to zero and back to normal several times and the latest is an engine noise that my very reliable, 6 year auto service provider has told be is related to the timing belt assembly/mount points and as it gets louder, the engine will be getting ready to fail. So, I read all these complaints today and felt like I could have summarized everyone's complaints and concerns. I am an accident investigator and have no doubt that this vehicle will go down in history as one of the most unreliable and dangerous cars ever built. Shame the feds have not taken the extra steps to remedy the issues after so many complaints yet, they went after top selling Toyota at a time when the american made cars were barely able to stay afloat. Wonder?.

2002 Chevrolet trail blazer 67180 miles. Failed cooling fan clutch. . Read more...

Two weeks ago the clutch fan on my 2002 Chevrolet Trailblazer engaged before I left the house and never disengaged on a 15 mile trip to and from work with varying speeds (as low as residential, and as high as 70 mph). This is highly unusual for it to 'stick' in the engaged position. Usually it engages on a cold start and is off within a minute or two. I went so far as to turn off the a/c figuring this could trigger the command to engage the cooling fan. I called the dealer I usually have my work done at, and they just said to bring it by. On the approximate 25 mile trip from my workplace to the dealer, at some point the fan decelerated from the 100% engagement I had been experiencing for two days, it illuminated the service engine soon (ses) and the cruise control failed (it was in use at the time, and was dangerous in that it suddenly decelerated on its own at highway speeds). The cruise control was not functional at all. Upon arrival at the dealer, the fan had seemed to resume normal speeds, I relayed what had happened on the way here, and they hooked up the tech2 device, read the codes, cleared them, turned the light off, and then went on a test drive. No defect was noted and everything went for approximately one week. Currently, the fan engages itself to 100% at nearly all times except at high rpms or at highway speed. This occurs whether the a/c is on, whether it's a cold start, or a warm start. I can drive 20 miles on the interstate, and on roads at 40 mph the fan will slowly engage itself. At 40 mph there should be enough ram air cooling. If I accelerate at a rapid rate, keeping the rpms high, the fan slowly disengages. . . But rengages shortly after the acceleration is ended (downshift, deceleration in speed, etc). This has become troublesome as it is surely causing excess wear and tear on the engine, is wasteful in that it causes outrageous fuel consumption, and is dreadfully loud on acceleration. Currently, it has not turned on the ses light.

The clutch fan on our Chevrolet 2002 Trailblazer went out and the fan stayed on. It resulted in reduced engine power because the fan was pulling so much power from the motor. When our mechanic called for parts, the Chevrolet dealership had 15 on stock. Apparently chevy is aware of this problem but has not recalled it.

Trailblazer service engine light on, engine reving, seems to be fan clutch stuck in high speed, causes poor acceleration, poor gas mileage, and costs over 500 dollars to repair. Dealer in small town states they have replaced several in the same year model truck. Due to the high cost of this repair, I am forced to drive my vehicle until I can come up with the money to repair it. Hopefully it will not damage any other parts in the mean time. There seem to be several complaints that deal with this same thing. Also, the rear brake lights keep going out .

Clutch fan is causing vehicle to be sluggish on take off. Makes a loud roaring noise, burns more gas.

Since I bought this vehicle August 30, 2002 I have had to bring it back to the dealership on numerous occasions for several different items. I have had both the left and right brake lights gone out, the driver side head lamp went out, the air conditioner has gone out twice(four months apart), the driver side passenger window is inoperable(we have tried to get it fixed for almost a month now with no success) and the engine cooling fan was warped and the fan clutch malfunctioned. At this point we don't understand why they haven't just recalled the whole vehicle. Luckily we have the 36,000 mile warranty still in affect but what's going to happen when it is up and the same problems keep recurring?.

Engine fan clutch is making a loud roaring noise (2003 GMC truck).

I have a 2002 Trailblazer with a air condition problem the truck has been to the dealership twice. The dealership has told us to spray the Trailblazer with lysol in the air condition vents in oder to keep the meldow smell from coming back into the truck ,they are refusing to replace the air condition.

Cooling fan had intermittent problems of racing when you stepped on gas, now cooling fan is racing constantly. I have been told by the dealer and Chevrolet that a new part has to be designed. No one knows how long this will take. I have been told vehicle is safe to drive, however it certainly does not sound like it and I have been stopped by police thinking I am racing engine or driving unsafely. **dimsii ivoq entry posted after 12-12-02 cut over to artemis**770110.

The fan clutch was not operating properly which caused the vehicle to overheat. Please provide further details.
