2002 Dodge Ram 1500 Question: heater goes in and out
the fan works great, and so does the heat. The truck runs at regular temp,and doesnt leak anything any where. When I turn the contol knob to heat,most of the time I can hear the door open or close, which ever it does going to heat.But at any given moment the heat just disapears like someone turned the knob to cold. It can stay like that for a few min to an hour or so. I turn the knob back and forth at that point and it doesnt make any differance. When its ready, the heat starts comming out again like a new truck instead of cold air. What do you think is cousing the problem,the door, and if so how do I fix it? Also, this all happens going down the interstate at 70 mph - jamesc
