So I took my after market radio out of the truck because I'm trading it on Sat. and now the air or heat will only blow out the top of the dash. The blower motor sounds like it always does and the temp of the air can still be changed just when you turn the selector switch to the floor lets say, nothing happens and air will only move out the top of the dash. I took the control panel loose to look for a vaccum line or something that had come apart but found nothing. The good news is the stock radio head unit sounds great with the nice speakers I installed! Bad news is I need to get the heater/ac work fast! Any help would be great.
