2002 Dodge Caravan heat and air problem

I have a 2002 Dodge Caravan and the heat and air only works sometimes and only when I have it on high. Can anyone help me?

Welcome to the forum

My guess would be the blower motor. Next would be the switch.

Pull the connector, at the motor, are they green ? If so shine them up with something like a real fine sand paper.

Try it again.........if not working tap the blower motor with something like a hammer. Don't hit it real hard. If it runs, you have a bad blower motor.

To check the switch you will a test light or a meter.

I pulled the blower switch apart on a vehicle thinking it was at fault when I didn't have #2 or#3 fan speed. Some cars run a little resistor unit (in the main vent to keep it cool) that governs fan speed. Mine was blown on the 2 and 3 setting. cost 5 bucks to replace and took 5 minutes to do. It did take 6 months to find the culprit though!!

Thanks for the help. It was the resistor, but now my heat sometimes don't come on at all and I took it in and I was told it was not the motor. He told me I had to take it to a dealer for some modular and have the electical system reset. Any ideas how much this will cost me?
