My turn signals quit working yesterday. When I applied the lever, the right or left signal lamp would come on, but not flash. I pressed the Hazard lamp button to the rear of the gear shift---nothing!

I thought, "Oh well, I just replace a $4 flasher and I'll be back in business!" I soon found out that the required Bosch flasher/switch costs close to $100. Figuring I had nothing to lose, I removed the flasher/hazard switch combo unit from its wiring harness and put it on my bench. I carefully pried it open, noting what parts go where. I disassembeled it as far down as the circuit board. The relay was still below the board---which I could see through a hole. I decided to leave the board in place. Then I squirted a bunch of WD-40 down the hole in all directions. Then I sprayed all the contacts---which stick upwards towards the button.

Reassembly was easy---carefully tuck the contacts up into the swich assembly after installing the two button springs. Do not attempt to install the two spring steel slips which hold the assembly in the console----they can more easily be added later. After it snapped together, then I installed the clips.

I then installed the flasher back in the car----and it works perfectly!

This item may cost near a hundred bucks to replace----but it can be opened, cleaned, and put back into operation.

Don't know where you're pricing the switch at, but the first place I looked on the internet had it in stock for $17.07 and it's made by Hella. The Dealer wanted $28 (list was $42 if I remember correctly) for the switch last month when I inquired about it after mine started acting up. It wasn't making the left side flash when I turned them on. I still haven't replaced the switch, maybe after the hot muggy summer is over and I don't have to work in 95* plus heat with the humidity even higher.

Man what a jump in price for '81 and below. I didn't think about there being any difference in switch used in the 6 year production run of the 123 model 240D, I sometimes forget that mfg's make all kinds of running changes in same model and even same years at times. Glad mine is less then $20 shipped.

$19.38 at FastLane.

For anyone reading this, the $19.38 fastlane mentioned here is the switch only, on later models the switch doesn't include the relay, the relay is separate and can cost $100+ from the dealer
