Question Asked: Why is my heater not working
January 01, 2010, 01:05 PM
There are actually a few symptoms that are occuring. 1 - the heater doesnt warm up at high speeds and barely at low speeds. 2 - When accelerating up a hill the defrost blows out air instead of the current setting (I assume a vacuum problem) but cant find a vacuum check valve that applies to this van. 3 - the blower motor only operates on high ( I assume a resistor malfunction). 4 - while idling there is a funny noise and (I am assuming it is the idle tensioner)Could alot of these issues be because of the idle tensioner?
