Hi guys, long time no post...

I have a problem with my windshield water fluid. It's full, but it won't spray washer on my windshield.

What's even more puzzling is that I can hear the little pump working. The nozzles are not clogged, because I un cliped the hose from the little fitting clipped under the hood, and it doesn't drip from there.

The Haynes manual is also silent on the subject (surprise, surprise... )

What can be the problem? Can it be clogged from inside the tank? Can the pump be faulty even though I can hear it whine? How tough is it to remove the tank? Do I have to remove the airbox? Can one buy a replacement pump, or do I have to buy the whole tank assembly?

Thanks in advance.

Mine does the same thing when its very cold outside. The tips of the sprayer on the hood freeze up. I only use the orange washer fluid at full concentration.

Well, it's not the frozen nozzles issue. It won't spray liquid through the hose at all.

you may have to pull the tank from under the hood and check the pump itself to see if the outlet is plugged. a hose may have some crap in it that you may have to blow out, you should be able to do it by blowing through the hose to dislodge what ever is blocking it up. the hose should be in sections so you wont have to pull the entire length of it.

I might shoot some compressed air in the hose and see it makes bubbles in the tank.

Odds are the bottom end is frozen solid (tank area at the bottom is really pretty small and frankly shaped coincidentally something like an ice cube tray) and that is where the pumps are.
How do I know? Just did mine today for the same reason. I've had this truck for less than a year, but haven't been driving it much ('93 4Runner). The washer fluid in the resevoir was what the car lot had put in it. Most likely plain water with a little blue tint
Throw in a few nights of zero and below temps and voila one non-windshield washer fluid pumping Runner. Easy to disassemble on the 2nd Gen. One nut and one bolt holding the battery tie-down and one bolt holding the resevoir.
With two pumps, there are two plugs. One is low by the bottom of the tank, the other beside the battery. Unplug both. Two hoses too. Separate them at the closest joints to the bottle. It'll take a little twisting, wire moving, hose canoodling, but it'll come out.
Pour out the fluid and then stare at the big block of ice at the bottom. Flush it out with hot water, put it all back together then fill it up with a good concentrated wiper fluid meant for wintertime.
Worked for me anyway
Good luck!
