hey guys can you help me out? my 2001 acura cl 3.2 heater and front defroster doesn't work! my heater only blows out cold air as if the A/C was on. the anti-freeze in my car is full, I check it every week. I even tried turning on the heater and defroster in the summer to see what happened and only cold air came out. Does anybody know what could be wrong? I need to get my defrost working b/c where I live it's starting to get really cold and the windshield ices over and I can't see through my windshield clearly. If anybody can please help me out?! It would be greatly appreciated!!

Thank you!

 

You need to check the heater core valve. It's in the engine bay near the firewall, inline with the heater core inlet hose. If you can find that hose you won't miss the valve.
