Question Windshield washer motor

My windshield washer is not spraying. I want to test the motor and can't locate it. I have found what appears to be the headlight washer motor up by the battery (and its not working either). Is the windshield washer motor behind the dash. How much trouble is it to get to?

The windshield washer pump is indeed up by the battery. I replaced mine but it still didn't help. Strange thing is, that I found this nasty algae slime growing in the fluid tank and it had plugged up the strainer on the suction tube. If the pump is spinning, then look for clogs in the system.

If that is the windshield washer pump by the battery then where is the headlight washer pump?

Well, I can't help with the headlight washer pump, but I can tell you both that one (two actually) of the most common parts to cause a problem when trying to get water on the windshield is the pair of valves that are in the line just under the windshield cowl. Up at either end of the cowl under the windshield are what looks like 2 plastic elbows (actually one's an "L", pass side, and one's a "T", driver's side) When these valves get old they stop working. Also, my pump got clogged with crud, you can take the thing apart (4 screws), clean it out and it will probably work like a champ.

It's pretty easy to take apart and inspect. My pump gears corroded. I dressed them up on the flat sides with 600 grit. One pass did the trick. I then polished the facings with simicrome.

On the brass backing plate that was etched from the corrosion. I tried polishing it the same way. I read on the board that all you have to do is flip it over if the opposite side is virgin. I bought a new pump just in case at a swap meet. I have had the cleaned up pump working for 2 years now.

Does someone know for sure where the pump is? The pump by the battery is burned up but I was told it was the headlight pump. Where is the windshield washer pump? behind the dash or was I given bad info the the pump by the battery.

The pump by the battery is definitely the windshield pump.

I did a search for "headlight washer pump" and found this thread which may have more info for you,
Windshield/Headlight Washer Plumbing Help Needed

Quote:
The pump mounted on the large reservoir with the big hose is for the headlight washers. The smaller one inside next to the AC condensor fan is for the windscreen.

PS How do you know for sure that the pump by the battery is no good? Do you see physical damage or it just doesn't work? If it just doesn't work then take it out, take it apart and clean it, then hook the motor up to the battery with some test wires. That's the best way to check the motor. You could check for continuity across the contacts, but even that's not a definite check.

Thanks for the location info. Last night hotwired it to the battery, leaving the ground connected and I heard nothing while a little smoke sizzled up. I assume it is cooked. I could try cleaning it up. Thanks again.

Hmm, well, mine was not working, so I cleaned it and then hotwired it, but if you saw smoke....

I can back Masraum up on this issue. I just had my windshield washer system fixed. The pump is definitely in front of the battery. My system was clogged, so the mech blew out the lines with compressed air, after which the system functioned for about a week. Went back and had the two valves replaced, works like a champ.
