No power at the wiper motor??

Sorry, its a 95 pathfinder but i dont know who else to ask Im working on it for my boss. So the wipers dont work, if we put power directly from the battery to the wiper motor they turn on. But we moved the volt meter around and did not find there to be power at the motor. So the motor is good. The fuse is good. Is there a relay for them somewhere? could that be bad? what else could it be??
Thanks alot guys!!

I would check the grounds and see if there is power at the wiper switch. Does the washer pump kick on?

I pulled off the wiper switch, dont know where to start to check power lol but the washer pump kicks on for the rear but not for the front. Also, the rear wipers do work.

the rear is a completely different circuit. It looks like they all have power except the black and blk/blu wires because it's a ground side switch.

so your saying at the switch, the connector that clips iinto the switch should have power on at least one of the wires. And if it doesnt what could it be? the fuse in the cab is good and there is power at that fuse

Then there's a break in the wire or a short somewhere between the fuse and the switch.

ok thats got to be it because there is no power anywhere on that connector but there is a ground that has continuity with the frame. The rear wiper has power. Isnt that wire run off the same fuse? couldnt I just jump a wire from that power wire to the front power wire? what color?

Also, if that amplifier was bad would it cause there to be no power at the switch? or does power go to the switch first then the amp?

it looks like the power comes from the motor to the switch. I'm starting to get confused by it, so I'm gonna read a little more about this system.

Ok, If i plug the connector in to the switch, and provide direct 12v power to different wires on the switch, i get different things to happen with different wires, the washer fluid squirts with one, the wipers turn on fast with one, and slow with another and so on. So, providing direct power to the connector turns **** on. Now what? Is there one main power line that goes into that switch? i need to know which one that is?

So you've narrowed it down. So it's just not getting power to the switch? How about the power going into the motor? Check the blue/yellow wire going into the motor.
