Thanks for the offer but unfortunately I have more wall art than I have walls. Hopefully others here will take you up on that RL price though. They really are great pics...would look great hanging in the garage, game room, office, etc.

Also, remember that the ballast resistors(located behind each fan in the front wheel wells(total of 2)) control the low speed setting of the fan to which it is attached. These resistors are known to go bad. I believe it is far more common for the resistors to go bad than the relays, although it is far easier and cheaper(you can simply switch the relays around to test) to test the relays. When the resistors go bad the fan will not operate at the low speed setting, although it will continue to turn on in the high speed setting when coolant temps reach approx 102 Deg. C. So if after changing the relays(there is a low speed and high speed relay for each fan(total of 4 radiator fan relays)), your low speed fan setting still does not work then you know it is a blown resistor on the side that is inoperable.

A quick way to check the low speed fan operation is to start the car and turn on the AC. The fans will always run at low speed(unless the engine temp is too high, in which case they would run on high speed) while the AC is on.

Hi all,
I've just picked up on this and have a few questions if anyone can advise. Did anyone figure out which was the ground on the relay? I've read the posts and can't find an answer and when you run the two grounds from relay 21 and 22 I take it you connect both to one side of your switch and then run a ground to the chassis from the other side of the switch. I'm thinking about a gen Porsche switch as I've got a couple of spare slots, has anyone tried this?
