Front AC/Heater Fan Out, 2001 Dodge Durango

Now get a wiring diagram & continue on

Replace the resistor. I know you say you tested it.

If it only overheats at idle..then check see if there is a electric fan in front of the mechanical fan..I know the 2001 has one ,,but im not sure of the 99..You have to look with a flashlight ..Look into the mechanical fan towards the front you should see the blades of the electric fan,,if it has it...The electric fan should come on instantly when you turn on the a/c

it is possibly the switch, fuse, wires, or fan motor. use a test lite to check for power at the front fan connector with key on and fan switch on high. if you have power, fan is bad. if no power, check fuse, if good, you will need a wiring diagram and a bottle of prozac

Check the blower motor resister. Hope this was helpful.

Check the Blower Motor Resistor. This controls the Blower Motor/Fan Speed.

use 50/50 mixture of coolant/water, use synthetic oil or no more than 5w 30. Change thermostat, make sure fans come on when idleing, otherwise change relay

What exactly is the "round plug type thing" near the firewall [passenger side]? Is it a sensor of some type? I, too, have a coolant leak here on my 2001 Durango; its tucked in rather tightly near the hood/firewall corner. My electric fan is not kicking on; vehicle overheated tonight. (4.7 liter)

I have a 2001 Black Durango that had the same problem. There is a resister to the right of the ac/heat blower (underneath the dash on passaenger side). This needs to be replaced. You might want to replace the motor as well. Both are real easy. I had replaced the resister first and everthing worked fine for about 6 months and then my ac/heat would only works on high. I replaced the motor and now it works just fine. The resister was about $15 at dealership and the motor is prob around $40-$50. I hopes this helps. Good Luck!

Electrical cooling fans not coming on due to bad sensor, fan relay, or bad fans. Check thermostat and coolant temperature, too....accordianman
