Vents blowing both Cool AND warm air
I had a new AC compressor put in my 2000 Eldorado in June. AC worked fine all summer. When I turned up the thermostat for heat, cool air is blowing out the left vents (driver side and center left) and warm air is blowing out the passenger vent and center right). My coolant is full.

Re: Vents blowing both Cool AND warm air
Your coolant may be full, but I seriously doubt your refrigerant level is at factory spec. This is a very, very common symptom when an a/c system losses more than half of its refrigerant charge. Pull your refrigerant weigh it to verify loss, then vacuum, and recharge to spec and notice all is okay.
