Question Details

Trying to find a fix on heat. After I changed the front blower fan, I am only getting AC and barely any heat. Any help is appreciated

Do a search for duo-valve and try to find out if your model has it. Which I believe it does. The duo valves get stuck and don't allow any coolant to flow and heat up incoming air. 


Also have you switched the air direction? Do you get hot air by the feet or defrost?

Best I have been able to find out is that it does. Same at feet or defrost, the heat was great till I changed the front blower motor and now it's almost non existant. As idle it's cold, when moving it's luke warm. Do you know where the value is located?
