Windshield Washer Pumps (Front and Rear) Not Working - MS Gen 2 (2012)

[ice_man5210]

Hello, forum people! I hope you're collective wisdom can help solve my problem-- I have a Gen 2 Montero (2012) and suddenly both front and rear windshield washer pumps stopped working. The wipers work, though.

I have tried to check the fuses but there seems to be no fuse or relay for the washers and the ones indicated for the wipers are okay.

Any suggestions on how to resolve this would be greatly appreciated.

Where is the windshield washer reservoir? Based on where the filler neck is, it looks to be behind the driver's side bumper below the headlight. How do you access it? Does the bumper have to be removed?

Thanks.

get close and personal, and hear if the motors whirr when turned on. if they do, then it's probably the washer fluid level or clogged plumbing..
if the motor does not whirr, my default suspects are the switch or the relay, or the fuses.

i would check the fuse diagrams, in the manual and on stickers or imprinted onto the fusebox covers..
these appliances always have fuses.
if not dedicated fuses, they share fuses with other appliances.
what other gadgets in the vehicle do not work?

generic rersponse.
i don't monty.

Do you have evidence of rodents in the engine compartment? They could have chewed through the wires. They like nesting inside the fenders right where the reservoir is.

Similar issue happened to my car but the part that got eaten was the water line. Easily repairable but irritating. Good thing they left enough length to work on. Covered it with flexible tubing to prevent future chewing.

I agree here.

nababawasan ba yung fluid? - if yes, then there's a leak somewhere
if no - check if the washer motors are running (may sound yun)

if you hear the motor and di nawawasan yung water, its clogged somewhere.

lastly, when was the last time na ginamit mo yung washer mo?

[ice_man5210]

thanks for the speedy replies.

I've listened to for the pumps while activating the switches and the I don't hear anything from them at all.

The windshield washer reservoir is full. I had initially thought it had run dry but when i tried to top them off, they were still very close to full.

I haven't been using the car very often due to the pandemic but I'm pretty sure the washers were working prior to the time i discovered that they weren't because when backing out of the garage I always spray and wiper my windshield because there's a lot of construction going on in my area.

We don't have a rodent problem but there are always cats hanging about the garage. I wanted to do a visual inspection of the reservoir and the pumps but cant figure out how to get to them.

Electrically, everything else on the Montero seems to be working fine naman.

It's kind of funny, given how many Monteros are out there, that there's not much information about the electrical system or how to access the windshield washer reservoir on the Internet.

In a different age, I'd have just brought the car to Rey's Electrical and had them look for the problem. but I guess now we have to make do with what resources we have at the moment.

Again, thanks for the tips and I hope you guys keep the ideas coming!

have you tried checking the car's manual?

have you tried checking the car's manual?

yup. looking at it again now. nothing obvious to me though.

I'll try to post some pictures of the relevant pages later, maybe you guys will notice something I missed.

Thanks for the reply!

in many vehicles, the reservoir tank is visible at a quick glance at the engine bay.

but if you can't seem to see it,
if you know how to fill up the reservoir,
all you have to do is to follow the neck. it'll eventually end up in the reservoir tank.
if i have to guess, it's located behind the front bumper.
have a clean higaan ready, so's you can lie down on the ground and espy it from under the vehicle.

Sorry for the poor quality of the pictures.

I found this, which seems pretty accurate with what I've been looking at in the garage:



which one could be the shared fuse/relay for the wiper pumps?

thanks, I'll try to do that.

I've been trying to look from the left front tire well and all i can see is the fender liner. Didn't occur to me to look directly from under the bumper.

if i may,
that's a terrible listing!
whoever did it, wasn't...
imagine #4, the "starter motor", listing the fuse at a measely 7.5 amp.
my car's fuse listing is nicer.

i guess you'll have to check each and every fuse...
pull out... look... push in.
next fuse...

okay I just looked. The reservoir is behind the bumper below the left headlight. I think access to it requires removal of the fender liner.

This is fast becoming something beyond my DIY skills. haha. darnit.

...thereon goes banawe...
heh heh.

i do hope it's only the fender liner that requires removal.
in some cars kasi, the entire bumper has to be brought down, to gain access to certain parts.

perhaps you can search google for instructions.
that may decide whether you do it DIY, or you employ the skills of the banawe boys...

some years back,
they did in 15 minutes,
what i could not do in 2 hours.

Remove the front left tyre. (use steady jack or secondary support jack for safety)

Remove the front clips only of the fender liner.

If you know how to "hawi" the liner to access the thing then you don't need to remove the whole liner as they are plastics that returns to original position.

Shine some light to get a better look of the obvious(wire harness, connectors), and maybe use a multimeter to check the coil resistance of the pump motor or the input voltage when the switch is activated.

Thanks for the instructions! I just might give it a try!

What I learned about changing the wiper motor is that upon changing the motor you will have to drain the reserve I mistakenly fill up my reserve with wiper fluid and ended up draining it upon replacement of the wiper motor.
