Exclamation No heat

I dont know what has happened but my heat will not blow hot, when i turn on the defrost its freezing cold and my dash vents wont blow out anything only on the floor, now the vents in the backseat blow fine what could it be? termostat?


And one more question do i have air shocks on the back of my bonniville? I ask because i am sittn really low in the back to the point when i back or pull out the drive im scrapping the muffler

You will need to check the air mix actuator, this is behind your glove box. Remove the glove box liner and then watch that arm to see if it moves.

The liner just clips in if I remember right.

The part behind the glove box is what needs to be checked for no heat. There are other actuators that control where the air comes out. If none of these are working then you will want to check the vacuum line that controls the whole HVAC system.

Default No heat

So found out the Bonnie I just bought has little to no heat. Blows cool air out of all places. Good thing it is spring. Engine temp looks fine so based on all the reading I have done on this forum seems to be I need to check the mix actuator behind glove box and/or flush heater core. Is the mix actuator pretty straight forward? Turn on the heat and some lever should change position right? Can I move it manually? How big a job is it to replace? Thanks for the help.
