94 BMW 3 series heated seats

Does anyone know how to hook up the heated seats in a 94 BMW 3series. His drivers side seat doesnt work but he wants the passanger one hooked up. Last time it was in my shop I remember probing the wires at the switch and not seeing anything that change polarity with the switch. I might just be retarded as well though. Give me a shout back as I have this car in my bay in about 2 hours from now. Thanks alot.double-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer

OK so if anyone cares, there is a WHITE/ yellow wire and a WHITE/ blue wire. WHITE/ yellow is for the back element and WHITE/ blue is for the bottom element. Must power up both wires with 12 volts for either element to work and the light in the switch will not turn on but the elements will.double-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer
