Well I have ran into another problem with my TB. I was driving home last night and had my a/c on. All of a sudden no air came out of the vents no matter what speed setting I had it on. I went in the gym and came back out and it worked fine. Now today I was in town and it just stopped. I turned it off and then it started working fine. I have the LT model with the computer climate controls if that helps. Thanks in advance.
