I'm replacing my wiper transmission & motor..just plugged it in and it doesn't work,checked the fuse..it's OK.. How can I check the motor to see if it works? How can I check the switch? Is there a way to "hot wire" the motor to see if it works? I had noticed on the wiper motor plug that there are #'s...
I guess if I knew what # was what it would help?
Can anyone help a newbee?????

What year & model car?

W202's have w/s wiper issues.
