Re: need help asap

So you have an aftermarket fan hooked upto the factory sensors in the hoses? The sensor in the top hose is for low speed and the one in the bottom hose is for high speed. The low speed will come on first at 213*, high speed comes on at 220*.Unplug the sensor in the top hose and turn the key on but don't start the engine. Next use a paper clip or piece of wire and jump the plug you should hear a click from the relay on the pass side fender behind the battery. Next do the same test with the lower sensor plug, if both relays click they're good obviously. Next test the fan by hooking it directly to the battery. Is your aftermarket fan a two speed fan? You can swap the sensors from the top hose to the bottom, they are the same sensors. I just looked through the FSM I have but couldn't find a way to test the sensors you can go here http://www.jeepslimited.com/index.php and once you register you can download the FSM free. I got a new motor for my fan cause the low speed was burnt out. I got the motor from Crapozone for around $100 part # PM9069 and you need to get a pig tail from Ford part # WPT-168 which I paid I believe $15-20. The reason for the Ford pig tail is because the motor is for a taurus.

Re: need help asap

Not sure about wiring the relay. The PDC on mine has that spot empty and it's blacked out on the cover also, only thing I can think of is that it's for a different model. Jump the top sensor like I said and see if the relay clicks, if it does and all the wiring and factory plug is still there wire your fan into that. The large brown with yellow strip wire is the high speed, the small brown with orange stripe is the low speed and the black is the ground. Do you still have the oem fan?

Re: need help asap

Yah I'll probably be out plowing in 9-10hrs, waiting on the snow to start. You can still do some testing of the factory wiring with out the oe fan hooked up. Just an FYI the stealer charges something like 700-800 for a new fan. Do some testing when you get a chance and report back.

ok the other day i checked the redish wire on the top hose with a ground light tester and the relay beside bat clicked ,did not check bottom one cause it was 23 degrees out,,this give me a thougt can i just sraight ground one of those to the frame and hook new fan to old power wire that ran to fac fan ,,i know that would run all the time but honestly i could care less ,,i went rideing around an old back road that goes around the lake here in the snow so i knew i would be going very slow for about 2hrs so i just hooked it up shraight and it made plenty of heat and stayed just under the notch under 210 if not on it,,not 210 the one before it and thats with a 180term so if anything i could go back to a 195 ,,anyway shouldnt that set up work or is those wires power instead of ground,,and if i do it i wana tap the bottom hose wires ,,if its relay works but dout it anyway thanks

Re: need help asap

Not sure if it would work if you ground one of the wires for the sensor. If you've still got the wiring coming from the relays, hook your fan to that and just use a jumper wire in the plug for the sensor. That way it will run when the key is on and shut off when the key is off. Or wire a switch into the wires for the sensor in the top hose and you can turn the fan on and off when you want.

Re: need help asap

When I put the switch in for mine, I cut the plug off leaving about 5-6" off wire left at the plug. I then used two butt connecters to splice the wires for the switch into the factory wiring putting the plug back on also, that way once I replaced the motor the sensor would still turn the fan on. As for the plug for the fan, if you look at this pic there is a red lock on the plug. You need to side that out, it doesn't come off the plug just slides out and then the plug will come apart.
