Air Conditioning problem
2003 Jeep Cherokee V8 Four Wheel Drive Automatic 67,000 miles
The heater on my Grand Cherokee has seemed to stop working. It has the fancy system. Automatic dual temp control, etc, When I try to turn on the heat, or set the temp control higher than the current temperature, it still blows cold air. The AC button is off. When I parked the car after driving a while, there was a small puddle of water under it like when the ac has been running.
I have had the car since it was new and am very famiiliar with the varied settings. I do not believe the controls are in the wrong position.
Is there a simple test; a simple switch; or is this going to be one of those " electronic brain box" issues?
It has been extraordinarily warm lately for here (Western Washington - in the 80's and 90's) The engine is not overheating. The car is garaged when not in use.
Is there something I can try before giving up and taking it to the dealer? If that is the path, what are the " worst scenarios".I am a widow on very limited income and don't want to walk into a big bill without understanding my options.
First turn it to hot (high temp) then pop the hood and see if the a/c clutch is engaged (front of compressor is turning) if it is the climate control is turning on the a/c. If not it may be a blend door problem. Turn the temp all theway hot, then cold, with the fan on high. You should hear adifference in thesound when the door goes from hot to cold.
