The wipers on my 1982 240d 360k miles are only working on high?
Does this mean the motor is starting to fail?

Thanks,

Bad contacts in the wiper switch. You have good ground and power, you are just missing control or input.

Don't forget to grease the screw and threads on the spring compressor.

On my 1981 240D, I had the wipers not stopping in the right place and sometimes not working. There is a wiper relay behind the fuel/oil/temp gauge of the cluster. That solved it for me.

Is there any way to take apart the wiper switch? I don't see any small screws. I might be able to pry the end off with a small screwdriver.

Any ideas?

Thanks,

Update - The problem was with the switch. The bad switch would only work on high and the wipers would not park.

I removed a switch from the junk yard and now the wipers work perfectly. For a 1982 240D you need a hex socket and not a 27mm socket like you do on other w123's.

I have 363k on the car. Hopefully this helps someone with a similar problem.
