#71 of 78 Re: 02 TB Climate control problems [darlanikki] by motorcycledave Aug 21, 2009 (9:16 am)
Replying to: darlanikki (Jan 17, 2009 7:46 pm) I have had the same problem with my '02. Did you ever find the problem? My TB started out reading 50 then it started giving my "ice possible" when it is 90 out. Of course this confusses the a/c. please help if you can Replies to this message: darlanikki (Aug 21, 2009 5:54 pm) motorcycledave (Aug 22, 2009 5:45 am)

Replying to: motorcycledave (Aug 21, 2009 9:16 am) After 6 months at a dealership that changed everything from the wiring to the compressor to the sensors, and the the main control unit, GM told me to take it to another dealership. I brought the TB to the other(larger)dealership and the first thing they did was change the outside sensor and the wiring that went to it. They kept it 2 weeks and drove it. They then called me and told me it was fixed. I have had it back for several months and I have never seen the 50 deg or "possible ice" message again. Here is South Louisiana, it has been well over 100 on a few occasions and it did, in fact, read 104 outside, which was accurate. I have had the first dealership call me to ask what the second one did to fix my A/C because they have had the same problem with someone else's TB. Other than replacing the outside sensor and wiring , that is all they told me. The dealership name is Trapp Chevrolet. They are located in Houma, La. Perhaps you can call them for more information. I know that the A/C now works. I hope you can get yours fixed a lot sooner than the 6 months that it took me. Replies to this message: motorcycledave (Aug 22, 2009 5:45 am)

#74 of 78 climate control knob by suzyruth Oct 07, 2009 (11:40 am)
My 2003 TB has cool ac but the knob that controls whether air comes out on floor, dashboard, or windshield vents does not work fine. The air will not come out of dashboard vents no matter where the knob is turned. This problem just started last week. Any hint to what I should do? Planning to visit beach next weekend. Please help!

I did not connect this to my problem in previous post but after reading lots of the posts from others I wonder if it could be related...just started having this ac problem after having car jumped off & then battery replaced????
#76 of 78 02 TB blows cold air on passenger side by puffinboy Oct 28, 2009 (5:03 am)
The heat works on the drivers side, but blows cold air on the passenger side. Stopped at dealer to get location on actuator to replace and see if that will solve problem. Other forums have mentioned the possibility of spraying wd40 inside but the dealer didn't think that was a good idea, saying it would gum up the vent. Any other ideas or has anyone had and solved this problem? Replies to this message: sharpie3 (Nov 15, 2009 3:57 pm)

Replying to: puffinboy (Oct 28, 2009 5:03 am) Same thing here. I have a 2003 and we get heat out of the driver's side, but cold air out of the passenger side. About a month ago, I replaced the exterior sensor because it was stuck at 50 degrees.   What's the fix for the heat situation?   Thanks
