No heat in cab
Fan switch works all speeds. Heater core is clean. Water flows. Sitting in driveway, I can feel heat blowing but as soon as I drive, air is ice cold. What gives??

Re: No heat in cab
It sounds like one of the doors is not in the proper position. The cold air is not passing over/thru the heater core and just coming directly in. Not sure where to test/start looking. Hopefully one of the more knowledgeable folks will chime in for ya.
