Have a 2002 durango and the front fan does not work but rear does

the blower resistor goes bad ,its upside down by the blower motor ,part at pepboys about 25.00 time to replace about 20minutes 2 bolts and 1plug it pushes up in the lower duc work its very easy to replace

I have a 2000 - the rear air is just a blower - it's not hooked up to the actual AC - just blows the cold air from front to the back

2003 durango, front fan switch only runs on high, rear fan switch runs fine in all settings

Check the aux water pump has power. The pump is locate on right side of engine compartment, between engine and frame. check terminal for corrosion.

ok, missed the part about the rear ac working, the part that causes this is called the air temperature control blend door actuator motor, it is an electric motor driven gear drive that moves the plastic door inside the air ducking to mix or shut off the hot or cold air from the ac evaporator core or the heater core, you will need to replace it.

Seems like a stuck relay, for rear fan. I'm not familiar enough with your car to elaborate further.

This happened 3 times to me. It's a $15 circuit that connects with 2 screws under the dash near the blower. Dodge should have recalled for this.

I have the same problem with my 2002 Durango. After accessing the rear HVAC unit you will find that there is a rear electronic actuator that operates a plastic door inside the duct system. The door switches the rear system between heat and cold. I had two broken items, the white actuator connector has a tab that broke off and the door inside the duct has broken where this connector fits inside. I am still trying to find the parts on line. I do not know what the part numbers are for these two items. Hope that helps, it seems to be a typical problem with the older durango's.

its the blower motor wiring.its a dealer part cost about $60 TO $70

blower motor resistor maybe why it only blows on high
