Windshield wiper Pump

[Army_Dude]

Let me back up and give you guys a little more info. The washer system was FUBAR to start with. I replaced the hoses and took off the reservoir to check the motor. The motor was rusted into and came out in pieces. I went to the Zone and got a new one which did not work when I hooked it up. I returned it and instead changed my rear end dope. Meanwhile I tried troubleshooting the problem. I first got no voltage whatsoever at the plug for the motor, I traced them back to the junction block on the firewall. I took it off and cleaned it the best I could with electrical connector cleaner. I put it back on and now I am getting a constant 12 V on the white wire. Whether I check the white and the red or if I just check the white and ground out on the block. When I hit the washer switch, voltage drops a little but not much.

I may be screwed up here, but shouldn't voltage be present only when you hit the switch? I'm lost in the sauce.

Oh BTW it's an 85 model.
