Default 1991 4.0 HO fan relay location?

Hey guys,

I've been poking around with my jeep trying to figure out why my e fan won't come on. I'm getting close to over heating when it's a really hot day and I'm stuck I traffic .

So far I have replaced the fan clutch,thermostat,new coolant.

My E fan does not seem to come on. However it will come on info turn the A/C on and it will also come on if I disconnect the connector on the temp sender at the thermostat housing.

Does my jeep have a fan relay? If so where is it?

Thanks!

Not in front of air box on drivers fender. If fans coming on with sensor unplugged Id say relays working .

What temp Is "close to overheating"? E-fan in my '93 would come on with A/C but not otherwise. IR thermometer showed that gauge was reading a bit high which was fixed with an OEM temp sender (in rear of head).

For future reference relay is in PDC but as freedgr said, if fan works at all, relay is okay.

I checked the relay and its fine. My temps get about to the 3/4 mark just befor red.

My temp sender at the back of the head for the gauge is new. Got not from napa a few months back when i did the cluster swap.

My fan won't turn on. Should I switch out the temp sender on the thermostat that triggers the fan to come on?
