    I have a 2004 trailblazer with 40,000 miles. We have had it over 2 months. When we first bought it the check engine light came on and we went and they reset it thinking it was the gas cap. It was gone and didn't come back again until last month. It has just came on twice and each time it comes on the car looses power and stalls. It turns right back on, but the check engine stays on for a while and then goes back off. Does anyone know what could be causing this?
  • The driver's side rear power window has now also come off the track on my '02 TB EXT. The passenger side did the same thing while it was still under warranty. Is this a common problem? It has about 56K on it now.
  • I took it to the dealer about two months ago and they said since I had bought several Chevys from them they would cut me a break. It was the viscus fan clutch. The service writer said that in '03 they fixed the problem. He said it was common on most of the light trucks and specifically the TB. I think the total was about $200.00. Hasn't done it since.

    A/C doesn't always come on right away. Sometimes drive for awhile stop the car and shut off the engine. Get back in and the car works fine.
    Also, the car seems to have other problems with memory. For example, hit seat reminder for driver 1 and 2. Sometimes the seat moves and other times it does nothing.
    Finally, at just over 50K I had to replace the water pump. Rub on that one was GM dealer in Minnesota would not help despite an On-star call. Chysler dealer fixed it in 4 hours so our vacation could continue. GM should not wonder why they are losing market share and will eventually go away. Customer service. You simply do not ever leave a customer stranded in below zero weather and tell them you can't look at a roadside problem. Shame on GM.
  • I have a Trailblazer and the remote keyless entry stopped working in both remotes. I put new batteries in and they still don't work. I went through the reprogramming procedure and the remotes still don't work. Any ideas? Is the vehicle receiver bad? Does it have its own circuit breaker (I didn't see a circuit breaker for remote keyless entry in the owners manual).
  • I just had my TB diognosed with a bad fan clutch as this under waranty?

  • I have a 2004 tb. I am going through this problem right now. The dealer has just told me today they need to replace the entire door, $1200. I'm reading all of these messages about tb's and I'm getting frustrated with chevy. Anyways, I read your club journal and I'm curious if my door is actually an $80 fix. I was told by the serviceman that the gate is a common problem. He explained in cold climates the ice can cause the mount to separate. I then called a friend of mine who previously worked as the service manager for a chevy/gmc dealership and was told by him that this is a common problem. He also mentioned that once the problem is fixed at the dealership, it's unlikely to happen again. I only read one message at this site that mentions this problem. I now make 2. I would like to know how many are actually experiencing this and if it is a cause for recall. If the servicemen are saying this is common, I would like to know what the requirements are for a common problem to become a recall.
  • I had the same problem with my a/c. I was told that the freon was over charged per TSB #02-01-39-006A. The underhood label cantaining the a/c charge specification incorrect. Charge should be 2.65lbs not 3.0lbs. I was told that with the system being over charged, the compresor could not properly cycle. Lets see if there correct.

    Sounds to me like they are fishing. My AC has never been touched since it left the factory. I gave up on the TB and traded it in for something that gets much better mileage. Too many problems. GM customer service less than satisfactory. In fact terrible. Hope your problem is fixed.

    I am aware that there is no EGR valve, the problem on the '02 is the emission equipment sticker says there is one. In California they go by that sticker when they check your emissions, so because when what GM said is there doesn't exist you are failed(visual inspection) because you "modified" the vehicle.
    There actually is a California smog advisory from May 2002 that addresses this(see below) Unfortunately, it appears all the "Professional's" I dealt with had no clue.

    Hello everyone,

    I'm new to all this but need help. I have a 2002 Trailblazer LTZ that I purchased new off the lot. For 2 and a half years it was the perfect vehicle, and until recently, made me very happy. Recently I've been having a very disturbing reoccuring problem with my dashboard and electrical components within.

    Randomly, all the lights will light on the console, the gagues all plummet to 0/empty/- what have you... the written console flashes with "Unknown Driver" and I get ringy dings to high heaven.. the car starts to shake and buck.. it almost seems like the power steering is going when this is occuring. It will go in and out of this state randomly.

    My truck has been into our Chevy dealer 3 times already for this occurence.. and all those times it was still under warranty. They have replaced things in the dash, replaced my ignition switch... and now it needs to go back. Now that it isn't under warranty, I fear what's going to happen, since they are clearly giving me the runaround, saying they will pay for it if it's being caused by the 'SAME' problem. But the car has been there a while and they can't seem to figure out the trouble. Has anyone had thier truck do this to them.. and was the problem solved??? Thank you for all your help.. I don't ever want to see this happen again, so any advice I could pass on to the monkeys that are fixing it, would really help me.

    :lemon: :cry:

    My wife drives an 04 TB, and you have to drive the thing for a couple of miles before the A/C starts to get cold. As long as it sits and idles it will not get cool. My Ford f-150 will start blowing cold air after 1 minute. Does any one else have this problem or is there something wrong with out TB? Thanks for any help.

    Wish I knew the answer. My 02 has doen this since day one. I have read several posts on this forum that describe it could be a low or high pressure a/c cycling switch that needs replacement. If yours is like mine, you will notice it more when the vehicle has been left in the hot sun for a while it takes a while to cool. Your are right that you have to drive it before it will cool. I did a test the other day and left it sitting in idle and it would not cool at all and I let it run for 3 minutes. Once I put it in drive, it would start to cool pretty quickly. Is there anyone out there that can tell us a fix?

    Have the same problem 2003 Trailblazer EXT, but I live in California, so not a cold temperature issue. The hinge separated from the glass and it appears to be some kind of epoxy that was holding it together. Seems like it should be a recall issue to me as it is poorly designed. Ridiculous to pay so much to get it fixed.
