Hot air not blowing (only some cold air) at defrost. Controls wont change cold to hot air OR from defrost to front panel or floor. Controls not changing temp or operating blend door. I checked fuses and replaced thermostat. How can I repair? Bad relay? Where? Vacuum Promblem? Just put in a new car stereo and started to blow only cold air defrost only. Help
