Oh and back to the meat head at Pro Cat - You know I asked him if there's any way to tell if one of the relay's is bad. He's telling me he has to test every wire in the car. I tell him he's not understanding me, I can tell a fuse is bad because I pull it and i can see the filament is busted. Is there any way to tell a relay like that? He insists it costs $100 to do that kind of test.

BULLSHIT. There has to be a way to tell a relay is bad. I know you can hear clicking if some of them are bad. Had that with the truck once. There's no way someone will make it so that you have to spend hundreds to test a two dollar item.

You already fixed it, but yeah you can check if a relay is good. It is most likely a SPST relay, they are the simplest. You need check voltage across the switched legs. When they relay is de-energized, you should read nothing. When it is energized, you will read voltage. 12V if it is just a relay for say the heater, could be 5V if it is in the computerized side. But I would check the voltage on the other side too, to see if your switching current is there.
