Windshield washer, Pontiac, 1985, Stationwagon, lining up two halves
 

I removed the front circuit board with the pump and the pump mechanism.
Now when I try to put the repaired piece back over the motor and back
plate I've got a real headache. The pinion that fits into the plastic
rotation wheel on the front, doesn't line up properly. I made sure I
didn't move any of the gearing on either, so what gives? Is there a
trick to it? (this is the old style that has the washer pump right on
the windshield wiper motor)

Look at the plastic four lobe cam, one of the lobes will have a
hole in it, there is also a hole in the steel body of the pump
assembly, place a 1/8" drill bit thru both holes to lock
everything in place while you bolt the pump down to the wiper
motor. Remove the drill bit when you're done.

Thanks, I'll 'give it a shot' in the morning.

Did as you instructed. Worked like a charm. Thanks!

Okay, it went back together and the wipers work but an annoying
problem that wasn't there before came up. In intermitant mode
the wipers don't pause at the bottom of the windshield now, they
pause half way across. Could I have still missed the pinion getting
put in the cam anyway? Or is this another issue?

Was the wiper motor in the park position when you re-installed
the pump?
Did you have the crank arm off of the drive end of the motor and
re-installed 180* off?

Yes. I took the front section (pump, circuit board) off with the
wiper motor in the park position and didn't turn on the wipers
until I reinstalled it again.
No. I didn't take the crank arm off.
Is it possible that the pinion is not meshed in the cam in the
right spot? The wipers work fine in all modes except intermitent.
Intermitent works, but the wipers pause in the wrong place on
the winshield.
There is a cam activated electrical switch. But I don't know
what the switch is for. It could have gotten bent? It's a long
piece of thin metal that flexes by a lobe point on the cam.
