I've been have some trouble getting rid of a Washer Fluid Light that won't go off in my dash. I've tried the obvious, and filled the tank, and also tried taping up some of the fluid lines at the joints, in case air was getting in. I also disconnected the Negative Cable from my battery in order to reset the computer, but the light keeps coming on. As a side note, it seems to go on when I hit a good bump, or the truck rocks from side to side. It used to go on, and then go off within a few weeks, but now it's been on for several months! I've thought about pulling the bulb from the gauge cluster, but don't really want to do that.
Any help you guys can give, would be helpfull! Thanks!
Have 1999 4Runner (Canada) so have the washer fluid low indicator light.
Came on, stayed on, washer fluid is fine.
Under right front of truck, take off cover (guard) to washer fluid container.
BE CAREFUL MIGHT WANT TO USE SOME PENETRATING OIL You'll probably still break a bold. I just removed the whole thing, cover & resevoir, but you don't have too. Might have trouble with hoses to pump motors.
ANY IDEAS ON HOW TO TAP BROKEN BOLTS OUT?
ALWAYS PUT VASOLINE INSIDE ANY RUBBER HOSE LINES MAKES IT REALLY EASY TO REMOVE IN FUTURE.
The stem neck, top of truck under hood, to the washer fluid container just pulls out; 2 separate pieces.
Pink sponge floating full indicator inside the neck has nothing to do with the light or sensor.
From under the right front you'll see a harness plug has 6 wires coming from it.
2 go to rear pump motor, 2 go to front pump motor, 2 go to washer fluid sensor. It's the one farther back more to middle of reservoir. You can disconnect the clips from the main plug & 2 motors.
MAKE SURE CONTACTS ARE CLEAN & NO CORROSION. SPRAY WITH WD-40, let dry, & PUT SOME ELECTRICAL GREASE BEFORE RECONNECTING.
Rubber seal around the sensor, it does not screw in its like the stem neck, lift the rubber seal around it and pull the sensor out, try not to pull the rubber seal out with its a pain to put back in.
The sensor has the male flat copper connector, very fine, wires have the female, BE CAREFUL ITS DELICATE. Dumb asses at Toyota designed & put that thing in and left the wires & contacts exposed whole thing could be avoided if it were just coated with silicone after install.
Anyways I just pulled mine put some penetrating & anti-rust on it wiggled it around a little and IT WORKS.
I think TOYOTA knows it, so they replace the sensor & 6 way wire harness all at once, that would be the easiest if sensor not working, Hard to see that thing going defective. Odds are it's the very bad set up where the wire plugs in at the bottom, it gets really badly corroded.
If the sensor is defective (?) you'll probably break the plug pulling the sensor off so its a fairly simple replacement with a new female, just get a new sensor.
I left mine exposed and just covered it with grease, but if you need a new sensor & replace the female plug coming from the 6 way wire harness, I'D RECOMMEND COVERING THE WHOLE PLUG SECTION WITH SILICONE.
Hope that helps.:wave:
