why does the ac pump activate when you turn on the defrost? The problem with that is I have a flexilite electric fan with the ac reley. So when the pump turns on so do the fans and slows the warm up? Anyone have a solution for me?

The AC comes on because it helps pull the moisture out of the air, wich causes the windows to fog up. I think the easiest way would be to put a switch on the fan so you can manually turn it off when it's not needed during the winter.

run a toggle switch so you can manually turn off the fans /forums/images/graemlins/thumb.gif
I thought it was so the A/C got cycled during the winter time. /forums/images/graemlins/dunno.gif I can't see how it would help make the air dryer on my later model rig because the evap and heater core are seperated. IIRC. /forums/images/graemlins/thinking.gif /forums/images/graemlins/dunno.gif
The air blows across the a/c coil, which is cool, causing moisture in the air to condense on it. Then the air blows across the heater coil, heating it up. Running the a/c makes the defroster work a LOT better than without it.
Electric fans need to be wired to come on with the a/c so that the pressure in the system doesn't get out of whack. Running the a/c with no airflow across the condensor is not a good thing to do.

i agree on not overriding the fans on the radiator/condenser. heat and pressure gets WAY out of whack doing it. think about it, mechanical fans work fine and they are on....
