Hey all,

I recently got my wrecked wagon all together and have been driving it for the last week. All has been perfect actually, minus the fact that I have no aux fans.

I jumped the relay at the high pressure switch and I can hear the relay click, but I don't have fans. I put power to the fans via a jump wire and they come on. I tried bypassing the step down relay and jumping the pressure switch, but still nothing.

I think I'm just going to wire them in to somewhere that has power with the key on. Any ideas on a circuit that would be good for that?

The fans were working fine prior to the accident, and there are no cut or loose wires to speak of. Not really sure what else to do here, it gets pretty hot sitting in traffic.

did you verify that the two fan relays' fuses are good?

did the accident involve the driver's sidste front? there's a resistor there....

run the engine and pull the plug on top of the thermostat housing...high fans should come on... if not you likely have a fuse problem

In my e300d - the wires on both ends of the resistors had burnt to a crisp, I had to patch in about 8 inches of new wires to make it work again.

The fans did not work on either speed.

Best way to repair said wires is to remove the headlamp. If you have 8 or 9 inch fingers you would be able to do it without removing the lamp.
