No pwr to windsheld spray motor. What could be the cause?
 

93 300E

checked:

connection ok
switch ok
fuse ok


it looks as if the two motors are connected in parallel.


thanks you.

Pull the connector at the washer motor, hook up a voltmeter and activate the switch to be sure the motor is getting 12 volts. Only way to know for sure.

The problem can also be a fault on the ground side, so don't assume that just because 0 volts show at the two pole connector the problem is on the switch side. Check from the connector to ground, and also from a known good +12v source to the ground side of the connector. By using this test methodology you can determine on which side of the circuit the fault lies.
