99 3.2 TL;

All of a sudden, the other night, the hot air turned to cold air!

I crank it all the way to 90... stil just cold air. Turn it down to 60 and it doeswhat it normally does (turns on circulation, AC, full blast ...works fine). However, NO HEAT! Just blowing cold air.

Any ideas? Engine temp checks out ok.

Thanks for understanding I'm COLD!! haha

Could be a few things. Heater Core, Heater control Valve, Control assembly, Air register, etc.

 

 

like he said it could be alot of things...check the module controls the temperature it might went out....its located under the passenger side dash right next to the ecu and center console....just watch it to see if ti moves when u turn the knob

 

Thanks for all of your help, guys. I got the DTC code which indicated a problem in the air mix control linkage, door, or motor. After doing so, I received honda_inspire99's suggestion. I found the little white, plastic lever that moves left & right. I could hear it was struggling when I changed the temperature, so I nudged it with a little brute force & it started moving as normal.

I THINK all is ok now. ...at least I know how to control the temperature regulator manually if need be!

Thanks!!

 

haha good job man, u can just reach down and change the temperature until u get a new one

 

check your coolent. if its low that could also be it.
