[Amc-list] Jeep Cherokee fan

You may want to replace your coolant temperature sensor - the one
located in the thermostat housing. That's what tells the computer when
it's time to turn on the fan.

And while you're at it, you might also want to wire a switch as you
mentioned so you can turn the fan on and off at will. That way you can
keep the fan running after you've shut the engine off. You could even
get tricky and wire in a delay switch that'll automatically turn the fan
off after a certain period of time, which would allow you to walk away
from the Cherokee after shutting it off.

  The electric fan in my '94 Cherokee Sport won't cut on automatically
anymore, hasn't since before last year. It's already starting to show
signs of overheating with A/C on, so I would like to fix it before the
hot season starts fully. I've tried swapping the plug-in fuse/relay in
the underhood fuse box for the fan, no go.  The fan works with voltage
jumped to it, so I know it's still good itself. So, where is the sensor
located that's supposed to trip the fan on located at? It looks like the
wires disappear into the harness, and I can't tell without ripping it
apart. In the interim, I may just run a hot-wire to the fan to a switch,
to have it running when the Jeep is. 

 Any help is appreciated from anyone else experienced with this problem.
Thanks!
