Um, I know it isn't working because the dash light comes on AND there's no light at the assembly (can check with car running and weight placed on brake pedal--this is how I determined which brake light). Light on was constant until I detached the assembly and fiddled with the wires/contacts, etc. Then it was intermittent. Sometimes when I depressed the brake pedal the dash light would go on and then flick off again. There doesn't appear to be a set pattern for this. Sometimes the light is on when brake pedal depressed and stays on until I remove my foot from the pedal.

My 60 service was on Monday Jan. 24th. My mechanic then replaced the bulb (it was not burned out), cleaned the contacts and used the dialectric grease. He says next step is to buy a unit from the dealer. I prefer not to spend that much if I can help it. I'm already looking at needing brakes and roters next month and a new power steering rack if the seal he used as temporary fix doesn't work (he claimed 50 to 75% success but only for 6 to 12 months). I trust this mechanic who has 20 years experience as a MBZ/Volvo specialist, but I'm a retiree with a pretty unexciting pension, so saving $$ is rather important.
