Windshield wiper pump failure replacement

[RHeinz]

I believe my wiper pump has crapped out on my 2.7L Badlands. Anyone know how difficult it is to access for replacement? Not sure you can even see it on the 2.7L installation.

I haven't replaced one personally, but it looks like the whole reservoir has to come out. Doesn't look very difficult though.

Just as a random thought: have you checked the washer pump fuse? I believe it's fuse 16. Took mine out to the snow last year during a deep freeze, and my summer blend fluid froze over. I mistakenly tried using my pump and it blew out the fuse.

When I got home and my fluid thawed back, I replaced the fuse and all was good again.

Ahhhh, excellent advice!!!! Hadn’t checked that. Probably the case as we just had a cold snap here in Houston…..19 degrees…..

Currently at the dealer to re-flash the wiper motor EPROM(?).

Thanks for the feed back on the disassembly and the fuse!

Saving this thread... I'm also in Houston and I normally fill to the brim with rainx brand before taking a car in to a dealer but I forgot when I had a trailer wire installed and the dealer filled me up with the cheap stuff that froze.

I'll check fuses tonight or this weekend and try to remember to report back.

Dealer (Joe Myers) just told me they are replacing the pump. Perhaps it coincidentally failed and not due to our freeze? Had the Green RainX in it….

Good info. I haven't checked my fuses yet, but weird that it failed like that randomly. Although after some searching it does appear to be an issue. Might even be a pinched line although I don't hear the pump trying at all so I think mine is dead as well.

My old Nissan I'm sure froze many times and never had a problem thawing out. Wife's Jeep Grand Cherokee is fine as well.

Fuse was blown in spot 16!

The spare listed in the manual was empty so I borrowed the 10A fuse for upfitter switch #4 which was next door to the washer motor.

After I put in a good fuse it fired right up. No damage from freeze I don’t think.

Got some 10A fuses on order for the upfitter replacement now.

For those who don't have a blown fuse, my pump would run but would not squirt. Very intermittent but got to a point where it was broke more often than working. I replaced it and tore down the old one. My best guess is the pump impeller wears down to a point where there is to much space in the pump cavity to cause lack of pressure to be created. It is a plastic to plastic mating surface between impeller and pump housing. There was no water intrusion into the pump motor, and the impeller was not stripped out, two things I figured I would find. The pump is shared with multiple models in the Ford fleet. I'm planning on this being a 3-4 year recurring issue.

A little late to the game, but I had issues with mine. Turns out the fuse for the rear window fluid was blown (slot 16 in the fuse box) which wouldn’t allow my front or rear to dispense. Swapped the fuse and good as new!

Thanks for the information, will definitely store that info!

No blown fuse in slot 16 here. Pump runs. Fluid trickles out of the nozzles on the cowling. New pump ordered from FoMoCo this morning. Will be replacing on my own.

Pump changed. Took longer to get the fender liner out of the way to be able to change the pump. Did it with front passenger tire still on. Removed original pump to find that the white plastic filter was completely plugged. Fiborous paper looking gunk.

I was too far in to not replace the pump (it’s $25). New pump on and washer fluid working as it should.

Total time 1 hour 20 minutes. Soaking original filter to get buildup out of it. Will keep as a spare.
