Its a 2000 model with a 4.0. Ok the fan works when jumped to battery and the relay under hood is good. I unplugged the temp sending unit and nothing happened. All fuses checked good. What else is there to check? And the AC isn't in the fan circuit on the 2000/2001 models.

 

Check the relay

 

Yep. Swaped it out with one beside it and started jeep then when i went to change them back jeep died. So its good

 

i hard wired mine in my 00. It would run sometimes but it was inconsistent....replaced sensors and had no luck. This does the trick, just have to remember to turn it on/off.

 

Check fuse #5 on the power distribution block (under hood) 40 amp.

 

If I can't fix it halfway easy that's what im going to do also. I can't find a good schematic for the wiring on the fan.

 

Its good thanks.

Look for the dark blue and pink wire on the distribution block and grounded if the fan starts is not getting the signal from the PCM.And yes the fan should come on with the AC.

 

Ok thanks

 

One more thing for the electric fan to come on the temperature has to reach 218 or above.

 

Yes

 

The A/C circuit will signal the efan on regardless of coolant temp.

 

Fuse #10 on the fuse passenger side controls the relay for the fan.15 amp

 

I can pull the relay and stick it back in slowly and feel it pick up. Checking on the ground wire now. I didn't think the Ac had any thing to do with fan on the 2000 and 2001 model. I turned Ac on and nothing happened anyway.
