Thread: heater problems/no heat

lately i have been trying to use the heater in my car. and it only works on the defrost mode but just barly. i have no clue whaat it could be. it just warm air, and also on all the modes like feet or heat or even defrost it only comes out the passanger side and on the driver side its cold air. ive checked the inlet and outlet hoses and the're just nuke warm. not hot. any advice would be amazing. its freezing and i need the heat really bad. thanks guys.

First I would check the blending door. A llot of times, over the years, they'll get dirt and grim on them and stick. If that's not the probllem, then I would move to the controls.

I am not sure if the blend door is for that as well, but you can check that and see if there is another one that controls the flow to the floor. O haven't been that far into the system to know for sure.

Good looking out gtpinsc. I won't even thinking about that.

i get air blowing to all the modes just not alot of heat. but could the theromstat be bad it it runs at opperating temp? cuz it does.

make sure everything is ok with your radiator/thermostat/fluid etc. My coolant elbow took a dump and I lost a lot of fluid, on the way to Brian's for repair, I noticed that the heat would blow only mildy warm, then cool, then warm. Heater core was acting up under those conditions.

ive been told by some machanics that if im getting some what warm air then the heater core isnt bad. i just changed the controls today and that didnt seem to make a difference. im going to try the thermostat but i rly dont think that is the problem.
