Wiper Motor Help for a Grand Am

2 weeks ago I had to replace a water pump in my 1997 Grand Am, well I managed to leave a socket under the hood that happened to get jammed under my wiper motor. My windshield wipers stopped working. I checked the wiper trani, I replaced the wiper motor with a brand new that I had tested first, I checked the fuses, those are OK and I replaced the multifunction switch. I am a GM mechanic and I have never run into this before. I have also had other mechanics (friends of mine) look at it and see what they think and none of us can figure out what the problem is. Like I said I have tested ALL new parts in another 97 Grand Am that I have and everything works fine in that car. Does anyone have any ideas on what could be causing the problem? I live in NE, where we get snow (and supposed to be getting it tomorrow) and I need to fix these things. ANY input would be appreciated! Thanks!

You need to test for power coming to the multifunction switch and going to the motor.

You should have 12vdc going to the MFS.

If you have power to the switch, then test for power at the motor plug. Remember you will have to have the switch to HIGH or another speed setting to see if you got power to the motor.
