I did see this bench test video but was hoping for some more preliminary trouble shooting info. Went to the Wilcox site and they have c-1 and c-3 trouble shooting but just the bench test of the c-2 motor . Not sure I have to take motor out yet. At this point I don’t even know if it’s getting power . Was looking for more initial things to check.

How is is it grounded , where do I check for power first etc.

thanks

Ok so I made to jumpers and I put power to the center prOng on the three prOne connector and I made another jumper to ground on the outer prong and as soon as I did that the wipers came on and operate fine

so what does this mean. I have power on the center terminal when I turn key on

is there a way to test ground on the other two sides of that theee side plug with test light maybe ?

Cleaned all six connections and applied dielectric and turn ignition on am the wipers parked themselves ( they were in middle of windshield from the direct jump test ) but they won’t turn on from switch. Very hard to get to back of switch I can feel the plug but very little room there afraid to in plug it may never get it back on.

Guess I need to take switch out. Any tricks to that ?

Take switch out and jump across the plug ?

I did run an additional external ground to mounting bolts of wiper motor but didn’t effect anything.

Thanks again to everyone

I do have a multi meter. Not that familiar with it or any electrical trouble shooting for that matter but learning quickly thanks to the generous and patient people of this forum.

When tou say use multi meter to ground plug under dash. Where exactly is that ? Right at back of switch ? I can’t seem to get near that too easy.

Dont know if this piece of info helps but when I press washer button I m switch I can hear selenoid clicking ? Does that mean switch is getting power ?

I am lost when it comes to properly checking the wiper motor for ground. When I had it running I ran a hot lead to center of the three prong connector and then ran a ground lead to the outside terminal and the wipers ran fine.

Did i by pass all other grounds by doing that.

I can see ground wire down to starter looks new and tight and clean. .

There are three plugs on wiper motor , the three prOng then a two prong and then a one prong are any of them grounds I should be checking ?

Thanks again

with regard to the switch. When I take set screw off and **** off what happens when I turn that nut with the two recesses the switch goes back behind dash. I just don’t see anyroom behind dash to get at this dam switch.

Electrical parts typically cannot be returned. It would suck to go through the expense and effort to replace the switch only to discover that the problem was elsewhere.

thank you very much but I already did order a switch should be getting it today. Not positive that’s what I need but seems likely.

I habe been able to test ground to copper strap on wiper motor and I get the same sort of reading I get when going between negative on battery to engine block so I assume that means wiper motor is properly grounded . When putting ohm meter to the outside prong on the three prong connector I get no reading at all regardless of what position wiper switch is in.
Guessing that means switch is not sending anything to wiper motor. But that can still be because switch isn’t grounded properly or switch is bad. Time to take dash apart.

Somone had mentioned that wiper switch is grounded to mount on back of radio. Can anyone confirm that. ? I am putting original radio back in anyway so that part of car needs to be taken apart already and may as well start there if accurate

Thank you for your offer though much appreciated.
