windshield washer pump died

[930slant]

The pump on my 88 930 factory slant nose whindshield washer system has died. Not sure how hard it is to replace the pump or should i just get a local shop to do the work? Thanks!

Easy repair. Just order the correct replacement motor and remove and replace.

I found that my washer pump wasn't working a few years ago. I ended pulling it apart and cleaning the pump gears and re installing. I'ts worked fine for the last 2 years. the winshield washer must not have been used in such a long time that it just corroded together. BTW it is an easy fix/replacement.

If the pump gears are just gummed-up or corroded, disassemble and clean the gears and housing with 9% pickling vinegar, rinse with water, final cleaning in Windex. Dry parts, reassemble, and test pump.

I think a new pump cost $20-30 if that helps. Mine was all corroded.

You can also flip the brass plate that is next to the gears in the pump over to get a few more years out of it if the gears are gummed up or corroded against the plate.

Thanks. You guys are great. I'll disassemble tomorrow and see what happens.

I thought my pump was bad. Ended up, the pick-up tube in the reservoir was clogged.

FIRST - be sure the pump runs -- stick your head next to it.

It may be there is a clog int eh line -- the L shaped drain back valves often clog.

Yup, make sure the motor runs first. Take the gearbox/ pump mechanism off and try it to make sure it's getting power.

I've never been able to keep the darn washer pump going once corrosion starts. Cleaning it is usually only temporary. I usually chuck it and get a new one. To answer your question, the hardest part is working the stubborn rubber grommets loose to remove the old pump and then punch them back in to install the new one. Use quality thin screwdrivers or a carbide steel icepick to patiently pry them off/on. The little backflow preventer valves get stuck shut, and the washer lines also get clogged. Also note the proper orientation of the wires. Brown is ground.

Also, regardless of the type of fluid you use, it's possible to get MOLD growing in the washer reservoir, which will clog the pickup screen. It's a real pain, especially if you have headlight washers, but it is a good idea to drop the tank and wash it out and clean the pickup screen if you are having any problems with the washer system (other than electrical).
