I have a 2002 Trail Blazer that I bought brand new and I have been wanting to get rid of it since the day I got it.

I not only have replaced the water pump and the fan, every light has been replaced at least 4 times, right now I don't have an AC it just died the other day!

A few years ago my 1, 2 and 5 went out on my AC control, but I didn't mind since I live in Texas and I usually kept it on 3 or 4 anyway. Well now its the end of August and I'm melting. Does anyone have any suggestions on what might be wrong with it.

I too have a 2003 Trailblazer. I noticed a few weeks ago there was a small ticking noise that stopped before I got out of the drive way (which is short). Now there is a large roaring sound to go along with it that lasts about a block or so. It's a great way to thank me for having bought a vehicle that is killing me with gas prices. Has anyone else had success with getting some money from GM for the repairs or at least the parts other than the few that mentioned it?

Same old story... 2003 TB, 30K miles, and in the shop getting a new fan clutch! Had it in to the dealer a year ago, because my electrical was resetting... needed a new battery at 25K! Still have the electrical problem, still hear the engine 'ticking' in idle (the GM mechanic insisted it was nothing), my outside temp gauge always reads 50 degrees (the GM mechanic suggested that I check it was in Fahrenheit and not Celsius), the auto shut off when filling up my car doesn't work, and last year, my 4 wheel drive went out. I will never purchase another GM product.

I too have an 02 LTZ Trailblazer, making that jet engine sound. I had the car checked out a few months ago and my mechanic said it's not effecting the engine. Will this effect the inspection on my car? Please let me know.

Our 2002 TB 'lived' with the fan noise for 40k miles before we started getting over speeds. Since the replacement we have had hot starting problems. Related to the new OBC programming? Don't know. Any one else with failure to start when at operating temperature? Starts fine when cold.

I recently brought my 2003 TB EXT to the shop due to a loud roaring sound coming from the engine. Thanks to all of your comments, I already figured out that it was my fan clutch. I was so upset about the amount of TB owners complaining about the problem that I contacted Chevrolet's customer service. I voiced that this concerned to should be looked further into. Right now, I am in the process of having my case "looked further into." Anyone have any similar cases where Chevrolet did something about it?

Our 20002 Envoy cooling fan clutch had to be replace at 54,000 miles. The cost was 800.00 and I called GM and nothing can be done. I told them you have lost another loyal customer and need to have a recall on this problem.

Happy Thanksgiving GM owners. Add another 02 Trailblazer to the list. My 02 TB has been very reliable until about 1130am today when my girlfriend called me to inquire as to whether or not it was equipped with a backup turbo engine. She said it sounded like an "air bus" under the hood. I have read all of the threads, but due to my current economic situation, I am praying that is the IDLER PULLEY. The check engine light is on also but I will go for the idler pulley first; if that does not work, the fan clutch is next via ORiely or ZBRA plus a local "mom and pop" auto shop. I can't afford to let a dealership "take me to the bank". At least I made it to 78k. Wish me luck and god bless all who read. Don't bail GM out!

Merry Christmas GM. Started on my way home; under the hood sounded like a 757 Jet liner going down the highway! I understand in future there going to be flying cars, but didn't know it was going to be mine. Always been Chevrolet man, but that's going to change. Mine has started at 85,000 miles. 2002 Chevrolet Trailblazer; this will be my last one I'll ever own. Trying Ford next, will tell you how it goes.

Well Loyal TB owners... let me join your club. My 2004 TB just turned 50,000mi and I'm also having the same problem. I already know from reading all the comments what I'm in for... But what I don't understand is why GM didn't recall this with all the complaints. To me it would be a safety hazard if on the highway and the engine decides to shut down. GM HELP YOUR LOYAL CUSTOMERS!!!

Dealership replaced the fan clutch yesterday (Friday) on my '02 Envoy (94k miles)... $486.88 for the Parts, Labor and PCM Update.

Went to work last night (27 miles away from home)... This morning, Envoy wouldn't start -- everything electrical was dead. Dealership is closed on Saturdays; $100.00 tow to another shop in hometown...

Shop manager says problem is not the battery or alternator, but rather a short... Something is draining the electrical system all of a sudden; told him of the fan clutch being replaced yesterday (surprise, it does have an electrical connection)...

Still awake and waiting to hear what's up.

Add one more to the list. I have a 2002 TB and in the past I had experienced an occasional "jet noise" as I accelerated but dismissed it after the dealership said it was nothing. Now, it is constant. The service engine soon light came on and I took it to my mechanic who I trust and he told me about a "bulletin" (No. 01-06-04-052B) that GM put out in May 2004 regarding: Service Enginee Soon Light On, Delayed Transmission Downshift and/or Excessive Fan Noise. With this, I took it to the dealership and all they did was reprogram it. As I drove away, the excessive noise started again and I called the dealership. They told me that they are only required to reprogram the system so the light doesn't come on. I asked why they didn't fix the fan noise. They told me that isn't part of the "bulletin". Apparently a bulletin is not the same as a recall and they don't have to fix it. I have to pay for it and it will cost somewhere around $500. Unbelievable!!!

I was thinking about changing it on my own, but now that I've read all of these comments, I don't want to keep a car that continually has problems and the GM company doesn't want to help the "customer".
