2002 Chevrolet TrailBlazer LXT from North America - Comments

Got a TB LTZ 2003 last september 07. Around 90000Km, got tha fan clutch problem. Now it's a bearing that's making weird sound. Otherwise, nothing major.

2002 Trailblazer LTZ. I too have had the jet engine noise. I just spent $1600.00 for the 100,000 GM recommended mainteinance. I mentioned the "jet engine" noise they said they would check it out. Found nothing wrong they said. Still doing it and now two months later the fan wobbles and I figure the water pump is going out. Great service Chevrolet. So much for that recommended check up.

2002 Trailblazer LTZ fan clutch 89000M. Purchased at Oreilly for $200.00. Doing repair myself. If at least GM does nothing about the problem with this component, they should look for ways of improving it to keep their reputation and I'm sure they will. I will always own GM products because I know that everything they make does not have problems and I enjoy the aesthetic attributes. Have had several during my lifetime from 1951 to current and realize that as with everything else, there are good ones and bad ones. Warranties are written for the reason that things just don't last forever whether we want them to or not. Don't get me wrong, I'm not proud of the problem but it if were my name owning the company, I would be sure to make improvements going forward. Good luck to all of you with this problem.

I own a 2002 GMC E. It now has 138k miles and in reality has been great. But I had a fan clutch go bad at 37,000 miles. Dealer agreed to buy the part and I paid labor.

Have any of you replaced the stabilizer links in front? I have had " clunk" on rough roads for awhile and have read that this is the problem but that they are easy to change.

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.

Yep another 2002 TB. I have not had the roaring that everyone talks about. We bought it 2 years ago with 47,000. We do a lot of highway driving and today it has 124000 miles.

We have had major electric issues. I was driving on the highway and all the windows starting going up and down by themselves and the lights as well. Mind you, it is about 8pm and pitch dark. My kids think it's a ghost and are laughing hysterically. I wasn't. We had to disconnect the drivers side panel so now the driver window doesn't go down, but it is a temporary solution to that.

The fan control first stopped working @ 1 and 2, but now it only comes on at 5 full blast so it's all or nothing. Now if driving and you put on the defroster, the engine idle drops, and if you stop while it's going full blast, it stalls because it's idling too low.

And new is the thumping in the right front. I'm wondering if this was the recall I just found on-line about the SUSPENSION:FRONT:CONTROL ARM:LOWER ARM. There are 15 major recalls and some 300 minor recalls So I am calling my local dealer Monday to find out if that's what it is. Anyone else have any of these problems?? Any suggestions?

Thanks.

The loud noise that every one is hearing is no doubt the fan clutch. I have 150.000 on mine and the roar just started. My check engine light came on and the code said coolant below thermostat. Replace the thermostst, it comes with the neck as well. This is a good job to replace. I had no roar until I replaced water pump. Now I have to figure this out.

To replace thermostat

1 Remove altenator bracket

2 remove small idler under altenator

3 disconnect battery bafore removing altenator

4 remove idler pulley bracket as this will give extra rome to reach thermostat housing

5 10 mm socket to remove housing and plires to remove clamp.

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.
