Hello,

It sounds like the motor is wearing out but to be sure lets test the power supply to the wiper motor and the 3 relays that power the system. Here is a guide and wiring diagram to help us do some easy testing to figure out what's going on.

Please let us know what happens.

Electrical problem
1999 Mercedes Benz C230 4 cyl Two Wheel Drive Automatic 149000 miles

I'm replacing the wiper transmission on my 1999 C230K. I've purchased a used transmission and have a new motor. I think that there must be a procedure for making sure the wiper is correctly aligned (synchronized with the motor) disassembly/reassembly. Can you provide this or the entire procedure for replacing the wiper transmission? Thanks!
