Have been having major trouble with the front end. Had it checked multiple times at the dealer and at a local mechanics shop and the ball joints and bushings had to be replaced. Even the the warranty was finished, the dealer did not charge me for this, but unfortunately I thought that this would take care of the noise on the front end, but it is still there!! also yesterday, April 24, 2007, I had to have the fan clutch replaced. This vehicle only has 35,000 miles. I have also had the service engine soon light come on and stay on several times and after reading other complaints, I should check out the gas tank for any cracks. This is my first and last GM product!!!! it spends more time being fixed then on the road. I have also had trouble with the rear tail light burning out, but that has since been fixed!

Faulty part - fan clutch - that innumerable amount if not 100% of 02-04 Chevrolet trailblazer and GMC Envoy owners have had to suffer with in the amount of $500+ repair bill. How many reports will it take for a recall...

Trailblazer EXT

  • Automatic transmission
  • 50,200 miles
I have a 2002 trailblazer with about 50,200 miles and the other day it began to make a high pitched sound, almost like a plane landing. When I took it to the dealer, he said it's the fan clutch and it's going to cost $711 to fix. When I asked if this is normal wear & tear, I did not get a proper answer. The response was that this happens a lot on the Chevy & GM vehicles. When I called Chevy corporation, I was given a claim# & told that they will have to investigate this problem & then they will call me back in about 3 days to advise if they will help with the costs of the repair. Both the customer service reps I spoke with at Chevrolet corporation (800-222-1020) told me that they've personally never had such a complaint before and that this was new to them. But when I googled this problem for the Chevy trailblazer 2002, I got several web pages including NHTSA which documented this problem. This should definitely be a recall item. I am now waiting to see if Chevrolet will help and to what extent.

2002 Chevrolet electronic clutch fan failure. Many of these electronic clutch fans are failing in our area. Imo, due to high heat causing O-ring seal failure and loss of silicon lubricant. Imo, part is not well enough built to withstand sw heat.
