05 Serria Cold Air Stops, Hot Air Blows
Greetings,
I have a 2500HD GMC that the air conditioner will be blowing cold air one moment and the next is blowing super hot air. The compressor continues to function but no cold air to the cab. This is not a new occurance, it first occured two years ago and I was advised to disconnect the batteries and let the system reset.
It worked for a year and a half but in the last two months it has happened a number of times and seems to be getting worse.
Hoping someone can offer insight into a cure.
