Whoever owned my car before me really messed up the electrical on the car.

The PO installed a swich under the steering wheel that controled the aux fan, found that out after almost overheating last year.

Still had problems with it not cooling, found the fan was going in the wrong direction, corrected this.

Yesterday the fan stopped working. Connected directly to the battery, spins fine.

My question is this.......

Can I just connect the fan to the pressure swich so that the fan turns on when the AC is running? Thats the only time the car starts to heat up. Or will I have problems because that will not control the fan speed and the fan will be always going through the pressure swich?

Also, just to doube check everything, what direction should the AUX fan spin?

Thanks for any advice.
