Grand Cherokee 2001 cooling fan running
today when I went to the store,
I noticed that the electric colling fan was running after I turned off the Jeep Grand Cherokee 2001 - ok... maybe it needed to run. but it was still running when I came back. So, I drove to the dealer... $$ They had to replace the fan (said it was shorted) + relay (said overheated) . I would think that the sensor was the only culprit ? Where and how is the fan regulated, on/off, and the relay ? If the fan was "running" just fine, why did it need replacing ? relay package - 5017491-AB $86 cooling fan - CBG4F250 $60 Anyway - the ONLY way to get at all these parts was from the FRONT grill/bumper and that took a couple hours total... SO - for a $60-$80 fan - it cost almost $400 in labor !! |
Re: Grand Cherokee 2001 cooling fan running
I believe the fan is a reversible one like the heater fans with two
wires going to it, but could be wrong on a GC. If so, it could short and overload or overheat the relay fusing it on. The story is plausible. Relays usually need an overload to fail 'on'.

Guess your grill is harder to remove than mine. :/ As for the temp sensor, from what I understand, one of them is in the fan. > Mike > 86/00 CJ7 Laredo, 33x9.5 BFG Muds, 'glass nose to tail in '00 > 88 Cherokee 235 BFG AT's - Gone to the rust pile... > Canadian Off Road Trips Photos: Non members can still view! > Jan/06 http://www.imagestation.com/album/pi...?id=2115147590 > (More Off Road album links at bottom of the view page) > > P.Schuman wrote: >> today when I went to the store, >> I noticed that the electric colling fan was running >> after I turned off the Jeep Grand Cherokee 2001 - >> ok... maybe it needed to run. >> but it was still running when I came back. >> So, I drove to the dealer... $$ >> They had to replace the fan (said it was shorted) + relay (said >> overheated) .

I kinda doubt fan motor was shorted out if it was running normally otherwise. Relays do go bad but you cannot make as much mney on labor changing one of them as a fan. I think he got taken. ----------------- TheSnoMan.com |
