Heater blows cold air
My heater will only blow cold air. Over the past several months there were a couple of times I thought the heater simply wasn't warming up, but most of the time it was great so I thought it was just me being extra sensitive to the cold. We replaced the thermostat for other reasons, which solved that problem, but now the heater never warms up, it only blows cold air. I've been given a couple of suggestions, 1 - temperature control module (which when I search for price listings says does not apply to my model of vehicle) 2 - heater core, and 3 - the "flap" that switches from a/c to heat could be stuck. Is there a way to determine what is the problem without ripping out the dash of my van? We've taken off the underneath part of the dash but still cannot get to it all, and the whole dash seems like it will have to come out. Is there something that would help indicate to me what the problem really is?
OH! I have a 2001 T&C Ltd
