2004 Dodge Durango blower fan does not work

If your blower only worked on high before it quit, or didnt work on high before it quit,

You probably have a faulty blower motor resistor assembly. The part number is 04885635ab If you look on the bottom of the motor housing on the passenger side (about where the passenger toes would point) you will see a wire harness that is a long oval in shape and has 5 or 6 wires in it. You will need a 7 or 8mm 1/4 inch drive socket with a u-joint attachment. on the firewall side of the connector, there is a sliding lock that keeps the connector on the plug. you will have to slide the lock toward the drivers side and the squeeze a small blak tab to pull the connector off of the plug. Once the connector is off, use the socket to remove the 2 screws. It will drop right down once the screws are removed. Once it is removed, it looks like a 2 inch by 3 inch by 16th of an inch thick piece of metal with a plug on it. The resistor pack dissipates ALOT of heat so do not take it out until the truck has been off for 30 minutes or so. I priced the part at a dealership for $12.77

If you reach under de dash board passager side locate the blower fan plug... unplug it. with a volt meter check for voltage. get help to switch the fan speeds. if no voltage present you may have a burned switch or a fuse.if you get a good 12 volts. your blower fan is a core you need to get a new one at your nearest auto parts. your blower fuse you should be able to locate it inside the vehicle fuse panel not at the engine fuse panel.....

Dodge durango if i hit the fan box it comes on low fan speed, does it sound like fan or reistor
