My heater in my 98 S10 Blazer does not blow warm air, I have flushed the coolant and heater core, put a new thermostat in when I did intake gaskets about 6000 miles ago. The heater has not blown warm air since I bought it in 06', My buddies a mechanic and he said that there could be something stuck or holding the door that switches from hot to cold, but that sound very unlikely to me. Do have any suggestions?
