Mr. Scotty I hope you might be able to help me I have a 2008 Dodge charger for some reason the heater and AC unit is blowing hot air even though the car AC and heating is off seems to be stuck and blowing hot air can you help me diagnose what could be the problem I checked it fuses and relays for the AC and they're good I've been looking on YouTube to find out and figure this out and only one video suggest that the control module can be stuck on high heat overpowering the AC

No. 1-1


often a bad blend door stuck on heat, a giant cow of a job. You need to find a guy like me with a dealer level scan tool to do bidirectional testing of that HVAC system, there's no way past that on those stupid complex poorly made dodge systems. sad, but true
