I'm trying to trouble shoot the washer pump in my 97 GT because it's not working. I noticed in the wiring diagram there's a connector to the positive lead of the pump motor somewhere in the harness. I wasn't able to find it because it's difficult to track wires inside the sheathing. Does anyone know where it's located in the car? I already checked continuity to ground and verified that it's grounded.

Also, if it turns out the pump is bad is it possible to replace without replacing the whole wiper fluid reservoir? It seems to be integrated into it. Thanks for the help.

Why not test it right at the pump? Use a test light and see if power goes to the pump when switch activated. It the answer is "yes", it may be the pump. Or, it could be the pump won't ground internally and you can verify that by running it direct to a 12v. BAT+ source.

That's eventually what I did. I took a voltmeter to the connector itself and saw 12V when I hit the washers. Then for the kick of it I quickly tapped a 12V power supply to the pump motor and nothing happened.

Turns out it's pretty easy and cheap to replace. You just have to yank really hard on the pump and it will come out. Replacement at AutoZone was only $13. Everything is working again

If it’s anything like the fox bodies, it’s on the inside drivers side fender under the fuse box on the SN95
