2004 Tahoe z71 with front and rear unit. Not automatic controls
Rear unit heat and a/c working fine
The other day my car started making this noise when turning the air off and it will do it sometimes when turning the vehicle off. I haven’t had to turn my heat on in a while but did yesterday and it just blows air, like outside temperature air. The air blows on all settings (low to high) I changed blower resistor out about 6 months ago. Where it worked on the highest settings only. Anyways A/C still blowing cold but no heat.
