my ac and fan motor are working great but it wont switch to heat its like something is not switching or opening where do i start?
I would pull off the blend door actuator and swap it out with a new one. Or another option is to swap it out with one of the other actuators. The blend door actuator is interchangeable with the actuators for the mode-air doors and the recirculation-air door.preciate the help. my options pretty much suck i guess.
Welcome to the forum distrbd63.2008 Nitro Hello - Female here (with limited car repair experience!) SO, I had very little to no heat. You could feel the heat coming from the vents, however when the fan was turned up, it just started to blow cold. I checked my coolant and found it to be low. Not sure why it was as low as it was in the first place? In any event, I filled the receptical past the Min Fill line, and it seemed to have worked, especially after a couple of days. Seemed as if the heat was as strong as it once was. A few days later and we are currently in a deep freeze. Back to minimal to no heat. I have been reading several threads here and on other forums, and first checked the coolant, then checked the 2 hoses leading to the heater core, both were warm to the touch (not super hot), but the same temp on both. The fan switches to the various modes in the car (i.e. defrost, feet only, face only). The temp guage on the dash is ALWAYS in the middle where it should be. AND I just removed the negative battery cable (as the previous post stated, for re-setting purposes?) I really don't want to bring this into the dealership...yet! Any help is appreciated in advance!
Yes, just get the engine to normal temperature (doesn't matter how you do this), then give some revs to move the coolant around the engine, the trapped air then floats to the top of the cooling system, even a slightly low coolant level can stop your heater working.(Sorry if this sounds like a dumb question)..Can I let it run till operating temp, and then run at high idle/high RPM without driving it?
