I have a problem with my windshield wiper motor. It does not spray any water at all(yes the reservoir is full). The fuse is good and the blades rotate fine but no water sprays out. I went to the junkyard and replaced it with another motor and I have the same problem. Does anybody have a clue what is wrong here? Any help would be appreciated.

One of the hoses could be plugged, or the one from the reservoir could have a hole in it and be sucking just air. It's also not unheard of for the blades to wear out and not be able to suck any fluid through the pump. Try blowing through all the hoses so clear them out first; then try a known good pump to check things out of the hoses are fine.

Hey Pete, I have tried blowing through the hoses and I was able to get some water to spray out. It sprayed about halfway up the windshield. Maybe its the pump. Do you know how much these cost?

It's very rare to have something blocking the washer fluid lines, but check them anyways. If you find that they are good, go to your local auto parts store and ask them for a windhield washer pump replacement. Generally, the pumps in junkyards are just like the ones in your car, and that means that the impellers inside the pumps have disintegrated at the center where the driveshaft is. The unit just plugs into the bottom of the wiper motor and costs about $15 at Autozone, were I got mine. It may be hard to remove, as there is a rubber washer that surrounds the unit and holds it in place, but a pair of water pump pliers should do the trick. Plug the new one in, connect your washer lines, and go.

 

Thanks for the replys. Are you talking about the piece the 3 hoses go into? I have replaced that for like $5. I also went to Kragens to get a replacement pump but they did not match up. Which piece are you talking about? I attached a pic. Thanks.

Sorry. I forgot to mention that GM produec two different types of wiper motors. On ones like mine, there is a rear black housing and that has the pump inside. On the other, I ain't sure where the pump is. Sorry for the confusion.

 

What year car do you have and do you have a bird or camaro? Does your pump look like mine or different?

 

Yes, it's different. I don't have a picture of itbut here's a link to one like mine on eBay. You're wiper motor is probably the one mounted in the washer bottle. I reccommend going with one of these motors as the pump tend to wear out a lot and is easier to replace here:

That motor pictured is from an 82 or 83. It works by moving a plunger to force the fluid through the lines to the nozzles.
Your best bet probably is to get one of the $15 or so replacement washer motors and attach it to the firewall by itself. For wiring, take the plug from the wiper motor that has only two wires and connect them to the new pump - don't ground either of them as it won't operate that way. The new pump should be marked 'in' and 'out' by the hose fittings. If it doesn't squirt anything try reversing the wires.

Ah, washer motors... those little jerks.

I've had 3 die on me and I haven't bought a 4th one yet- it's been years.

The metal motor shaft spins a plastic impeller- if the lines drip dry, and the motor spins the plastic impeller against a "dry" housing, the motor strips out the middle of the plastic impeller.

That makes the motor sound like it's working, but guess what, it's not spinning the impeller, which gives you no water at the nozzles. Fun stuff! One day I'll grab one of those bottles with the pump in it (for the rear window), and rig it up instead of using my current pump. For $20 you'd think they'd come up with a little better design then a plastic impeller.

 

Thanks everyone for the info. I will try that and let you know how it works.

how do i get the pump out? does the clip get pulled down or out? mine is mounted on the wiper motor!! thanks gearheads i love u

 

There's 2 tabs at the bottom of the pump, where the washer lines connect to. Spread them apart and pull the pump straight out of the timer cover housing. It will pull out hard, especially if it's factory original.

 

thank you sir...i love my 87 firebird......i cant wait to wrap that badboy around a tree this winter in MI
