i was driving for the past few weeks and occassionally the turn signals wouldn't work. Then at other times they would. finally a week ago they stopped working permanently. Not sure what to look for. Fuses? Vaccumm problems?

what year 240d? Sounds like your hazard flasher switch in the console.....but depending on the year, you may have a seperate relay...just forward of the shifter, I think?

I just replaced mine (1981) - everything is built into one unit (thus the $90 cost) and it controls everything. Lots of info on here about cleaning them out too, many times they are dirty with years of abuse.

I'd check your fuses/bulbs first (vac. has nothing to do with your problem).....pull the hazard switch next....and if that doesn't work, check your grounds.

This is common problem - tons of info here on the forum to guide you.
