Looking for a little help...

The electric fan on my '98 XJ doesn't seem to be kicking on.

Can anyone help me troubleshoot??

I checked the obvious like connections, wires, fuses, and no dice!

Thanks in advance!

Well, if your willing to play around a bit...

Grab some extra wire and wire it directly to the battery. This will tell you if the fan is dead.

If not, then I just wired mine directly and hooked up a switch. I know, not the best fix, but it was a trail fix that I haven't gotten around to fixing properly yet.

Before going to all the trouble wiring up new, check the capacitor in the wire harness going to the fan. My last two Jeeps had bad ones. $1.00 at the JY. Little orange plastic thing sticking out of the wiremold near the plug.

There are 2 things that will turn your electric fan on:

1.) Anytime you turn your A/C or Defroster on. It comes on immediately. This is a good way to test it.
2.) There is a temperature sensor on the T-stat housing which senses when the water gats to a certain temp. and then it turns the aux. fan on.

So if you turn the defrost on and no fan. The fan itself or wiring is bad. If the defroster turns it on then, your temp. sensor could be or related wiring could be bad.

Thanks for all the help!

What does a replacement fan cost if the original is shot?

Thanks again!

id say hardwire it mine is and i love it it helps heat up faster when its really cold out and if you are goin thru deep water you can turn it off so that you dont break the blades on it. i kno thats how the army trucks are its pretty nice i think
