I have an 03 tahoe that I just purchased used... i installed an amp and sub last week, and when i put everything back together... the dash vents are doing something really really weird. And to make it worse... it is related to something electrical or in the computer... :ack:
The vents are stuck on only DEFROST, however the A/C doesn't turn off automatically like when you turnt he vent nob over to only defrost... (per the manual) When you start the truck, (control nob is pointing to dash only vents), it goes from previous defrost setting, TO THE DASH FOR 3 SECONDS, then back to the defrost vents as the fan speed automatically kicks up a little...
It does that every time you start the truck... never blows out of the dash vents from the nob, or the floor vents for that matter. i reset the battery and ecu and that didn't fix anything.
BTW it is the bottom of the line tahoe, cloth seats, normal nobs, nothing fancy...
I'm afraid to take it to Chevy...
Any help is GREATLY appreciated!!!
