question = When I turn on the heater, it only blows out cool air. I can
hear the air pressure drop when I switch the temp. control from cold
to hot. What could my problem be?






JK:
Hello and welcome. This sounds like the heater core is plugged up. With not enough cooant
flowing throught the core, the air temp. wont get hot enough. This is as long as the temp
door in the dash is moving.
