help-changed battery in 03 now ac problem

[danmanaz]

Help,,,Battery in 2003 LT went bad-2nd in 3 years-dealer replaced first one under warrnaty. One month out of warranty battery bad again-replaced with top of the line duralast. Now fan blows out defrost vents or on your feet-not where it should-seeing how it's 110+ now in AZ. ????? Any ideas? First time I connected it the car wouldn't start and radio wouldn't power on--disconnect and wait a few minutes and then everything seemed fine except for no air coming out of dash vents. Much depression for not getting extended warranty after reading these posts....Anyone seen this? Thanks

Hey....

I have the EXACT same problem with my 2003 Bravada after replacing my battery. Have you found a solution? My only thought is that AC blend motor got shorted. The HVAC on this truck has always been a bit squirrly anyway.

Thanks,

Matt

I thought I had read somewhere that the digital climate control system had to recalibrate itself if the system looses it's power source?!? I'll see if I can find that post....
