Question about 2001 Pontiac Grand Am SE
Other symptoms will include insufficient radiator fluid levels a faulty water pump a stuck closed thermostat a plugged heater-core .. 1st check the fluid to ensure its full and at specified temperature also note the cable inside under the dash to the heater may have slipped as well however that's just another note as well as the vacuum lines are not all dry-rotted and by bending them especially the one that goes to the round ball is on and tight .
with the engine warm and the heat switch turned to full check with your hand and feel the hoses going into the heater core itself if the top one is hot and the bottom one is cold your heater core is clogged and needs to be back-flushed in order to loosen up all the gunk that accumulates within it ..if you need instructions how to do this feel free to ask ...
yeah try moving the switch around and ensure the switch goes from vent to defroster and to heat etc....if it is not doing this its possible the vacuum lines are off or bent or otherwise this you can write me if this is not functioning .
the heater core itself will be somewhat a chore but 1st let's make sure this is your issue before jumping into the deep end 1st ..i hope you can appreciate my humor on that one ...but yep these are the steps i would take 1st to properly diagnose why you lost heat ...hope this helps you .
