I don't know unless the pump is bad. I have a 98 XLT that the front washer doesn't work but the back one does. So it's not the pump since the same pump is used for the front and back. It may be the switch, GEM, or a relay... but I'm not smart enough to troubleshooting.
I found a fix for this...Unplugging the negative battery cable for 15 minutes then reconnecting it did the trick. They both started working again. I read that it had to do with the BCM needing to be reset by killing power to it.
AnswerIf the bulbs check out OK then I would check for a loose ground wire.Replace your turn signal switch, that's what I had to replace to get mine working again.
Might be a bad heater control
They often stop working for maintenance on the network like every other site does
Probably the turn signal/hazard flasher went bad. On some vehicles they are separate units, but on some vehicles they are the same unit.
either the washer motor has burned out or there is dirt in the washer lines plugging up the washer nozzles.
They might be plugged with dirt, etc..
most likely the fuse is blown
Fuse or windshield wiper motor.
If you were in a wreck you could have damaged your washer fluid reservoir or hoses leading to the spray nozzles. Slightly fill your reservoir with water and observe for leaks.
Blown fuse or bad wiper motor.
If Your Question Is That You Are Not Getting Much Water Onto The Windshield. Look For The Screen To Be Partially Stopped Up In The Washer Fluid Tank Or The Hose. Also You Could Have A Small Hole In The Line Not Allowing The Unit To Pull The Fluid To The Wipers.
Your washer fluid is low, or the indicator is stuck. The washer bottle would have to be removed and checked.
I have a 02 Explorer and the washer pump is on the windshield washer tank. So I would check there on your truck. Good luck.
Possibly freezing. Make sure you are using Windshield Washer Fluid and not water.
Most likely minor damage to Flux Capacitor.
The dealer would be the first place I would check.
