What would be good to do is......

I have AC on my 51 GMC stock 228. I use the stock fan, 6 blade and there is a compressor controlled elect fan in front of the condenser to push air.

I have thought of wiring in line the power line from the compressor to the fan with a hot toggle switch to turn on the fan even when the compressor isn't on. (Like in stop and go doing traffic) This would require a diode to keep the power from feeding back to the compressor when the toggle switch is on.

Don't know what diode would be best or am I barking up the wrong tree to get this accomplished? Experts? Your opinion for both of us?

Thanks, Mike
