The heater seams to be stuck on in my 90 series rv 6. I found the heater tap on the fire wall the cable looks to be moving the tap the tap isn't leaking are they known to corrode inside the tape .By the feel of the hoses I think the tap is not closing properly is this possible or should i be looking at something else.
Also the taco rarely works where would I start to find out whats wrong with it?

Heater taps are plastic so no corrosion behind the dash is the heater/air mix box... the heater/cool air knob controls the heater tap and also a large flap inside the box this will have been broken or disconected somehow... get your head under the dash while moving the dial around youl soon find how it goes
