Mine had a similar problem with the fan noise and loss of power. My local dealer replaced the fan clutch and reprogrammed the Powertrain Control Module (PCM) with new code which repaired the problem, all under warranty. That was about 10k miles ago and I haven't had a problem since.

Could not have said it better myself. This car is an absolute dog and the Chevy dealer is just about worthless. I have experienced each of the problems you've outlined minus one or two. I tell everyone the car is nice to ride in, but REALLY needs work! Mine now sounds like an airplane taking off because the clutch fan is going quickly at 48K miles...700 BUCKS!
No more Chevy's for this kid!

I concur with all the above comments with reference to the chevrolet trailblazer being a lemon. I was just informed by the dealership that I also need a fan clutch. my mileage is @ 45,000. the costs including labor is $766.00. I've had problems with control arms, rear gate and passenger side weather strip and other issues. also, this vehicle is not worth the costs of repairs or buying. I will never buy another chevrolet.

I agree. My fan clutch has been giving me problems since just after I bought the Trailblazer. The dealers keep saying that they can't replicate the problem and they have not heard of any other complaints. Two years later and at 42,000 miles it is going to cost about $800-$1000 to replace the fan. Coincidentally the manufacturers warrants runs out at 36,000 miles. Chevy has a terrible service and repair department. If you want to buy this truck go ahead just remember to get it serviced somewhere else.

The 2004 Trailblazer LT sways from left to right when being passed by another vehicle at 55 mph and above. vehicle feels as if it wants to veer off the road. Also, when this vehicle hits a bump it feels that you are about to lose control. At 55 mph and above in rainy or wet road conditions, it is my feeling that this vehicle could be unsafe because vehicle feels loose in the front end and have very poor road handling.

Wow... having read this I now know I'm not alone.
We've been having this problem with the Air Conditioning for the past year and a half. It's not blowing as cold or as hard as it should be, but it seems to make a lot of noise.
We've had the roaring issue repaired as well and it did seem like we lost power when the roaring engine thing happened. Dealer did try to play it off as though nothing was wrong.
We've been in about 5X now for the A/C issue and it's there right now. It's beginning to get absurd. I'm really starting to get peeved at Chevrolet.
I'm so over it I'm about to trash this thing and get something else. It's not been too bad overall and most issues are addressed, but I feel like I'm getting the run around on the A/C issue and it's not being resolved.

My 2002 Trailblazer is having many of the same problems. The rear driver side door no longer opens from the outside. I have brought it back 2X for new door handles. I don't have the time to sit and wait for it again. The rear hatch glass opens without notice. (always when I am on the highway) Chevrolet says that this can't be possible. The wiper blades turn on for no reason, and I have replaced numerous rear bulbs. Its hard to believe that one can go through so many bulbs in under 25,000 miles.

I have also had several problems with my trailblazer. My 4x4 went out, had to reprogram. Rear windshield wiper arm replaced (still not working correctly). Tail light went out about 8 mo. after I purchased the vehicle. Not to mention all the recalls on trailblazers. Now my fan clutch needs to be replaced. Plus a couple other of items had to be replaced, can't remember at this time. I am selling it as soon as I get this lemon fixed. Can't even imagine what's next. ANN.

I've had similar air conditioner problems with my '99 Chev Suburban recently. The front air does not seem cool during the day, while it flows somewhat cool in the evenings. The rear air blows cold consistently. My mechanic, after replacing a pressure switch and an orifice device... at modest cost... still ends up recording cool temperatures on his gages when I bring the car in the shop. But when I drive it off, the front air does not blow cool. Does anyone have any helpful ideas about how to solve this problem?

My 02 trailblazer did not start on coldest day of year so far in St. Louis. Everything hooked to battery worked, but when key was turned there was nothing. I had it towed to dealer they found nothing wrong. It started for them, but it was about 20 degrees warmer. Anyone with similar problems or remedies send email to jimcova @charter.net.

I also have a 2002 LTZ. It's a love hate relationship. Electronically the car is a nightmare, seats, auto wipers, lights, environmental controls, air, mirrors, auto seats, just about everything electronical stinks. I love the power, ride, albeit getting noisy now, and towing capabilities. It is understandable why Chevy is losing out to foreign well made competitors.

Since I purchased my 2002 LTZ Trail Blazer it has been one night mare after another. The electrical systems regarding modules have failed. The dash instumentation have failed on several occasions. The whole electrical module in the drivers door panel had to be replaced. The 4 wheel drive transfer module had to be replaced at 60K I very seldom use the 4 wheel drive, but when I needed it, The 4 wheel drive did not engage. I also have had the windshield wiper module replaced and have had the brake lights not function. The recall was to correct this problem. Today 8/16/06 The brake light does not function and the dealer advised that the tail light module must be replaced at a cost of $250. I also have had a love-hate relation ship with this vehicle, dealship & GM customer service. It is no wonder GM is loosing market share.
