Question about electric fan

Noticed on my 2001 durango, that I have an electric fan as well as the manual clutch fan and wonder when it's supposed to come on. Should it come on when the A/C is on, or just when it reaches a certain temp?

Both. it comes on at about 215 I think...but don't quote me on that. It also comes on with the AC

Hmm...I have never seen it on, so I wonder then. Does anyone know if this would not work correctly if the blower fan resistor is not working. Blower motor only works on high. Gonna replace it once I get paid.

yup...what he said....both...but not sure about the temp it comes on

as long as your clutch fan works as it should, it may never come on unless AC is on

AC or defrost turns it on only, so turn either on and it should kick in. Your truck probably won't see 215 unless your pulling on a hot day or have cooling issues.

When sitting idling w/ the A/C on, it starts to warm up in this AZ heat. Like I said tho, I've never seen it on...Have to do some testing to see what's up I guess.

Have you turned the A.C. on and checked to see if it was running? There is a fuse for it under the hood IIRC if it doesn't work.

I did check, and no worky...checked fuses, and all are ok. Gonna check the relay later today. Does anyone know if the blower motor resistor is bad, and only blowing on high, if it would somehow affect the electric fan in engine bay from operating?

The blower motor resistor should not effect the operation of the electric radiator fan. I think you either have a wiring issue, fan motor issue, or a bad relay if all fuses check out.

Yup resistor won't hurt it at all. Swap the relay with one you know is good just to try it out, make sure the wiring right at the fan is good as it's in kind of a shitty spot (right under the fan shroud).

Something else to check: There is a thermostat switch(usually screwed into a coolant area) sorry I dont know where it is on your truck. This switch senses the high temp of coolant and switches on/off the fan. IF you find it, you can test it with boiling water & a V.O.M.

Did a little research(should have done it before I opened my mouth)
On the Dakota(and others Im sure) The electric radiator cooling fan is controlled by the Powertrain Control Module (PCM) through the radiator cooling fan relay. The PCM will activate the relay after receiving inputs from the engine coolant temperature sensor and/or an air conditioning on/off signal.

Definitively, comes on at temps over 210 and when the AC is on regardless of temp.

HTH,
