Acura TL Heater

ok, winter is coming up, it was cold this morning so i turn the climate control to 90 leaving it on automatic. with this settings i realized that the a/c is not running so it fogs up my windshield, at the same time, it doesn't even get hot. I'm use to having the a/c running to compress the air to keep the humidity out and that still makes it blow hot air. but in this case, with the a/c on, it just gets cold like a regular ac still with climate control on 90. so whats up?? i noe the ac is not bad cuz it gets cold, is it just the heater? if so, is it something expensive to fix?

That sounds strange. The A/C should be on, regardless. Did you get any hot air, or only cold air?

Sounds like either the baffle that controls the air flow isn't functioning properly, or the heater core is messed up. If the heater core isn't getting any hot water you're just going to get cold. Make sure your radiator/overflow bottle are at the proper level too. Could also be the auto climate circuitry messing up as well. Unless you're mechanically inclined, I'd bring it to the dealer/mechanic.

Heater problem

I have the same problem and it looks like the motor air mix is the problem. It is located behind the console (access from the passenger side) after you have removed the glove box . It seems that the motor is weak and will not move the water valve which allows the rad fluid into the heater core in the cabin. there are 3 8mm screws that connect this assembly to a white plastic rod .
See the link here.

Hope this helps... on my car the motor operated when not connected but after it was connected , it did not move. You can check if it is working after you have disconnected it mechanically by rotating the temp dial on the heater control. as you rotate it the motor should move after about 2 seconds. Remember to connect it electrically to test...

My motor might be weak also, the last couple of seasons it seems reluctant to add heat!

Thanks,

Heater

The Part number is 59772... you have the correct one.... there are three screws (8mm socket) holding this to the housing .The electrical connector on mine is green. After removing the motor I manually moved the white plastic , which controls the water valve via a cable (in the engine compartment). I was then able to get heat in the cabin.

Hope this helps...
