My wiper comes on whenever it likes.

Asked by Mar 17, 2015 at 10:47 PM about the 1985 Mercedes-Benz 190-Class 190E 2.3 Sedan

Question type: Maintenance & Repair

It randomly wipes whenever it wants. I
believe there may be something wrong with
the turn signal switch arm

1 Answer


It could be a loose connection somewhere on the switch on the turn signal arm. Or somewhere else on the circuit. Buy a circuit tester and hunt the culprit down if you are doing the work yourself. Basic knowledge of electrical theories helps.
