#60 of 100 Re: 2004 trailblazer HOT AIR [rookergal]
Sep 13, 2008 (5:01 am)
When my TB a/c started acting strange, the external temp would go down usually to around 50 degrees, but sometimes it would go down to -35 degrees and the computer would tell me that ice was possible. All of this caused hot air to blow b/c the TB's computer thought the heat should be on. I bought a new ambient outside sensor for about $20.00 from the Chevy dealership part's department. Then I looked on line to see where the sensor was located and how to change it. It was pretty easy to change. It then took about 2 days after that for the a/c to work properly again. I don't know if the computer had to reset or what, but it now works great, just like new. Hope this helps.

#62 of 100 02 TB Climate control problems
Jan 16, 2009 (5:10 pm)
I have had my 02 TB LTZ at the Chevrolet dealership for 6 months now. They have changed every part that must be related to the a/c. Please see forum " 2002 TB AC Compressor problems" with attention to post 15-19. I have described all my dealings with GM and am now starting over with a new dealership at the "field engineers" request. Surprise!! They have started with the outside temp sensor and wiring, just as the other dealership did 6 months ago. This whole ordeal is just unbelievable. GM tells me they have had no other complaints about this problem. After reading how many others have had the same problem, I am wondering how many of you called "Chevrolet customer service"? I'm thinking there has to be more than me who has called to report this problem. They say NOT. Hmmm?

I called GM customer service after my TB had been in the dealership since July 1,2008. I explained what it had been doing and the dealership has assured me they contacted technical service and did everything they told them to do, but it still did not correct the problem. I did pay for the first repair, which was changing the outside sensor and wiring. I picked it up and about a week later, the same problem. From that time on , the dealership stayed in touch with GM tech support to try what they thought would fix it. Nothing did. Part after part was changed. I left the car there and checked in on it from time to time. They had no problem duplicating the problem, they just couldn't find the problem. In November, when I contacted customer service myself, they just couldn't believe my TB had been in the dealership for that long and not been fixed. It was not under warranty, it had expired by 2 months when the problem first came up. Like I said the outside temp went to -17 on a day when it was 98 outside. It then went up to 50. Of course the heater came on. When I picked up speed on the interstate, it would come back up to the real outside temp an start working. But, this was an off and on thing. Customer service has been in touch with the "field engineer" that was assigned to the case. Between the tech support and field engineer, they decided I should bring my TB to a different dealership, which they felt was more "qualifed" in the A/C dept. I did just that, but they told me it was the outside sensor and wiring, just like the previous dealership first told me in July of 08. I picked it up today and I still have my doubts about the A/C. Of course, it was way to cold to check the A/C to see if it would work correctly in the AUTO mode. I will have towait for warmer weather. I did not have to pay anything at all. They felt bad that it has been in dealership for over 6 months and no one could repair their automobile. Like I say, I paid the first time , but since that was not the problem, I have not paid for anything since that time. Why should I pay for parts or labor when they can't repair it? G. M has agreed with me and apologized the I have been with out a vehicle all this time. I mean I have not had it at all in 6 months. I did not bring it home for a day or two and bring it back. Everytime they replaced a part, they would test drive it and see for themselves it was not fixed. I was lucky enough to have an extra vehicle to drive. They did not supply me with a "loaner". I do not feel it has been repaired, but agreed to take it and try for a couple of weeks until the weather warms. I have seen many postings about this climate control problem with false readings for outside. I have told GM and both dealerships about it and they have told me they do not know of anyone else with the problem and told me I was a "one of kind" problem. I copied some of the postings and sent it in to them. I also told them to go online as I did and they would see it was quite common. Either they haven't checked or don't want to admit it is a big problem. At this point, I have paid no more and will wait a while longer. We will see........
#65 of 100 2003 Trailblazer hot/cold a/c
Jul 04, 2009 (7:38 pm)
I have a 2003 trailblazer that has decided to only blow cold air on the driver's side and hot air on the passenger side. This is timely as we are preparing for a 1800 mile round trip this coming week. Has anyone had this problem and been able to fix it?
#66 of 100 Re: Actuator problem [dwaynez28]
Jul 06, 2009 (4:46 pm)
I have experienced the same problem, no air out of the dash vents. I replaced the mode actuator located between the instrument stack and the glove box (had to use a come-along to pull a dash support over a hair to get the old one out and the new one in) and the control module (apparently only controls the fan) to no effect. I also tried the WD40 trick. There must be at least one more mode actuator somewhere in there? Does anyone know where it is and how to get to it?
#67 of 100 driver and passenger a/c not cooling the same
Jul 29, 2009 (2:00 pm)
Have an 04 trailblazer, noticed today that the driver side is much warmer than the passenger side. Both are set at 60 degrees, the passenger side is much cooler the driver side doesn't seem to respond to the setting. Any ideas?

I also have an 04 trailblazer and I am having the EXACT same problem. I am hoping to find a solution too.
#69 of 100 I had same problem
Aug 03, 2009 (5:33 am)
I had the same problem and am trying to remember what it was. Will have to check my service records. Although, after fixed, it still has its moments when the "blowing" is not the same througout all the vents...
