Then go ahead and grab the rheostat as well in case that's the problem. The relay is under the fuse panel. There's basically two levels of relays. Pull the cover off of the fuse panel, you'll need your torx 25, and then gleefully grab whatever is left (it's easier to get to the second level under the dash) The headlight relay is a double relay...it's black...I'm trying to visualize the panel in my memory...and I think it has an A and an E on it. I'd grab the central locking relay as well...those die, and the bulb integrity relay in the trunk. Hmmmmm what else would I strip off of an 850 and squirrel away if the price was right...the steering wheel (for the horn), the glove box (for when it locks itself), the fuel pump relay, the main relay under the cowl, the cam sensor, the hood release mechanism (for when it breaks), the pnp switch if it looked nice and new, the driver's side visor, the shift lock solenoid, the black trim that extends the length of the car over the windows and such (if it's nice), the master window switch, the glass out of the mirrors, the overhead courtesy light...yep...I could definitely spend some time with that car.
