I have the extended warranty but the dealer says I get to pay $175.00 so they can see if the warranty covers the problem.

Annoying that the blower for the a/c and heater does not work on all settings. It works on 4 only and very loud and either too cool or too hot.

Trailblazer LS V6

  • Automatic transmission
  • 51,000 miles

The air conditioner only works on setting 5. In San Fernando Valley in So. California it gets really hot throughout the year. This was my first dealer car. Everyone said, get a Toyota, get a Nissan they're really well made, but NO, I wanted to buy American. Will not make that mistake again. There are other irritating problems, but when I bought it, I really wanted a good working air conditioner. Monthly payments are painful enough and the warranty period is all out, so I'll have to wait. I think Chevrolet should fix all these problems at no cost or very little cost since it's their fault.

problem #5

Oct 012008

Trailblazer LS V6

  • Automatic transmission
  • 60,000 miles

My AC/heater has slowly been deteriorating. It started with level 3, then 4, now 5. I am afraid it is going to go out all together. It is starting to get cold outside and I am going to be one unhappey customer if I have no heat. It is already aggravating, because it is either full blast or nothing. Chevrolet should fix this problem since I see it has been happening to other people as well, therefore it has to be a malfunctioning product.

My AC/heater has slowly been deteriorating. It started with level 3, then 1, then 5 until none of my settings were working. It's a small pain now- we can roll the windows down. But i dread winter, i have three kids that are gonna be toting around blankets to stay warm in the car.

problem #3

Mar 102008

Trailblazer EXT 6 Cyclinder

  • Automatic transmission
  • 92,000 miles

The rear air will only work on the floor setting. Which really stinks in the summer for my children. It doesn't cool down as well when on the floor setting in the heat of the summer. There is also a annoying sound coming from the passenger very rear interior side panel ever since it stopped working. It sounds like a wood pecker. The sound lasts for about 1 minute after you start the car.

Trailblazer

  • Automatic transmission

I'm driving my daughters to gymnastics; it's 90 degrees out; the air conditioning is set on #2 and it just stops. I turn it off, then on again to #1...nothing. Turn it to #2...nothing. Turn it to #3...and it starts blowing like crazy. So suddenly #1 and #2 won't work, but #3 still blows like #3 should. This is a royal pain! We are all either freezing or sweating. Not to mention that I also have a 9 week old who is now NEVER happy in the car anymore.
