Well, it depends from washer to washer, but normally, you first have to find it's fetish. Then, you use that knowledge to be able to turn it on. Doing this, you can easily reach at least third base.
Fill the washer fluid or repair the level sensor in the washer fluid bottle.
Fill washer resevoir - if it does not shut off possiby a bad sensor
It means the agitator, which is the large center piece in the washer, won't churn and turn inside.
This is just a guess. If only the hot or the cold stops and not both of them, it might be that the washer in the shut off valve has come off and is plugging the line. When you shut off the main and then open another faucet, the back pressure in the line pushes the washer out. If this is the case, the washer should still be in the shut off valve. Turn off the main and take the stem out of the faucet. The washer should be the valve.
Check for a broken/damaged wire on the sensor that is near the bottom of the washer tank.
Just simply turn the washer off, then turn it on again.. :)
They come on when you turn on the windshield washer, but only when the headlights are turned on.
The hoses on the washer fluid pump motor are in the wrong locations. On the bottom of the washer fluid bottle, there is a pump. Swap the rubber hoses and it should work properly.
Try to turn it on.If it doesn't buy a new one.
The supply to the washer, the hot is supposed to be on the left side. On the machine, most have an H or a C beside the connection. Nothing will happen if they are reversed. Turn the washer on set on Cold and if Hot comes out, reverse them.
The rear window wiper/washer control is on the turn signal 'stalk'. It's the inner-most controls that rotate in both directions, with washer spray rotated all the way towards the driver.
Assuming you mean the low windshield washer fluid indicator, by just filling the reservoir with windshield washer fluid, the light should turn off. If not, the low washer fluid sensor may be faulty.
