Hi i have 96 and the po hotwired it also. May i know you returned yours back to stock setup. Thanks cheers

There is a temp sensor on the thermostat housing too is that the one i need to test? if so how do you test it? Any other suggestions as to what may be wrong? I have looked wiring over everything seems well i really dont want to peel open factory looms. This is on a 95 xj sport. Thanks.

This may help in your trouble shooting: on my 1992 Cherokee XJ, I turned on the AC then pulled the coolant temp sensor connector (front sensor) and the fan turned on after a few seconds delay. Try this to see if your fan works via wiring. You can also hook up 12CVDC directly to fan two check. Good Luck.
