Possible to rig the a/c fans to a relay and switch?

Can something like this be done to eliminate the belt driven cooling fan?

Jeff some people turn on their a/c when their engines are overheating off road, when idling a lot. In this case the engine fan is slowish. But I would not remove the main fan.

Dean,

my Rangie has been running warmer than I liked since I bought it, hence the mod. I simply disconnected the leads from coolant temp sensor (the one that controls the fans), and routed the wires to the dash-mounted switch.
Lately, it's been on nearly at all times.

So, IMHO, if you feel like you want to control the fans manually, you have cooling issues. A properly-running Rover with a properly-running cooling system should need NO modifications.

Peter,

I've seen 3 different vehicles, all of the fairly new, overheating in hot weather on the trails in the pine barrens. I'm talking all-day and all-night events, with lots of idle time and stucks. Those people turn of the a/c as a general fix.

Dean, the electric fans are controlled by both A/C circuit and temperature sensor. So they should come on on their own, and in my experience it was about 230F.

I am tempting my fate right how -
maybe my D1's temp gauge is stuck in the middle, but - it has never gone past this mark, on the highway (say, I70 towards Eisenhower tunnel at 55mph in the 2nd gear at 100F outside), or in sand pulling a Grand Cherokee, or in any other situation. Never tried mud, however.
Took me 4 years to not having to pop the hood on the jeep, though.
