well, if you can read electrical diagrams I will refer you to wiring diagram master page

if you can't, lemme know and i'll hunt it down for you and let you know in english.. and not circuits and diodes

I checked it out. Thinking the ground is a brown wire that ends at number 16 at the bottom of the page (second page in a/c diagram). I cold be totally wrong though. If I am right I have no idea where that is on the car.

Mine did the same thing until I opened up one of the relays, can't remember which but it wasn't the "big one". I suspect there was something blocking the contacts inside, dust IIRC. Has worked flawlessly ever since.
