Re: 99 chevy blazer air conditioning blowing hot air
Automatic or manual controls?
Was that recharge with freon one of the wal mart death kits with the stop leak and any oil and one hose one and one can and one gauge deals? What kind of freon did you add? We are going to need you low and high side pressure readings at idle and at 2K rpm with compressor running. Does the compressor kick on and run on ac on? Does the receiver dryer feel cold to the touch with compressor running? Is the ac controls switching from hot to cold and from vent to defrost to floor heat. Is the heater and defrost side of heater working good?
