Q: Blazer blowing warm air
My 99 blazer is blowing warm air, obviously it's mainly when it's really hot during the day. It has the right amount of refrigerant for the ambient temperature,it's been checked with a gauge. The compressor kicks on and I see no vacuum lines disconnected. I'm kind of stumped at this point as to what it could be. I've heard blend door could be stuck in heat mode but at night or when it's not so hot it actually blows semi cold air. Any help would be great!
