 Subject: 4.7L cooling fan keeps running
IP: Logged
Message:
I've got a 4.7L 5 speed that the electric cooling won't shut off. It got around 100 today, and when I got home the fan was still running after shuting the moter off. I figured no big deal, until I checked it 3 hours later, It was still going. I pulled the ground cable and thats where I'm at right now. Ya got any ideas for me? Thanks, Larry

What year do you have?
I know in my 2002 CC if you leave the fan on all the time. the aux fan stay's on or come's on/off all the time.
I would turn off your A/C and everything thing else and see if it still does it.

Hi Dakotaman I've got a 2000 CC. Never had this happen befor in the 3 years I've had it. If I don' disconect the battery, It will run the fan until it goes dead. I think a sensor has went bad, but I don't know for sure.

The temp sensor/switch for the fan is probably bad/stuck. I'd like to think when you turn the key it would override it though, maybe not.

I wasn't too worried when it was running after shuting off the engine, figured that was normal for such a hot day, but after a while I kinda figured something was wrong.

What was the final outcome of your electric fan issue? My 'oo 4.7 is doing the same thing lately. What I found is that if I have the AC or the defrost (which uses the AC I believe) the fan will stay on until the battery is dead. On the way to work lately I have to use the defrost for a bit. As long as I turn it off for a while before I get to work, it seems to be fine.

Same thing happened to me last year. The AC relay was stuck (melted the plastic underneath it too) As soon as I touched it, it turned off. Relay was red hot though, received a nice little finger burn. I switched it with my fog light relay. The relays are located under the hood. 2000 4.7

Probably the fan relay stuck.
I rewired mine with an external 40amp. relay.
The ones they put in are to small.

You can order 40 amp plug in relays from Parts Express. The shipping is a little steep for a single one (it's probably still cheaper than the dealer). Order a few spares or look at some of their other things...

At least y'all had a fan that kept running. The fan clutch went out in mine last summer in the 100 degree heat.

recently my check gage light came on and the temp
was really high. I have very seldom heard my
electric fan come on. but now it runs from the time
i start the truck to when i shut it down. I have a
2004 dakota 4wd that has belt driven fan and
electric fan. I understand that there are 2
thermostats for my truck. One regular thermostat
(that i am not sure where it is) and an electric
thermostat for the fan. could one of these be my
problem ?

you need to check for stored codes to help find the cause of the problem.

My 00 Dakota 4.7 Electric cooling fan will not
shut off. I have changed the temp sensor. Hell,
you can unplug the sensor and the relay and the
fan keeps going. Happened once before and I
replaced the relay. That seemed to fix it then,
but now it runs constantly. I just unplug it
when I park to save the battery. It does it
with the A/C on or off. It does it cold or hot.
Something has failed, but I cant find a diagram
that gives me any clue as to what it could be.
I can't afford The Dodge dealers labor rates.
Im considering hooking it up with ignition
power and just letting run when I switch the
engine on. Unless....someone out there knows
what the deal is.
