Can anybody help me figure out why my windshield washer won't work? I checked the wiper fuse and it's good. The reservoir is full...but no water to wash the windshield. Any ideas or suggestions? I have a 2004 Triple E Embassy.

First thing to check would be , for power to the washer fluid pump in the tank, with a helper pushing the wash button; then proper ground to the wiring . If you have power and the pump runs , remove the hose from the pump to check for flow . If you have flow, from the pump, then your checking for blockages in the supply lines to the wiper arms and nozzles.

My in-tank pump was DOA, so I just installed a new in line pump and hooked up the wiring from the old one to the new one. Works great now.

Happy Glamping.

When you push the washer button do you hear anything?

I tried to listen for the pump but could not hear good cause of the wipers...is there another maybe inline fuse? If not how can I check to see if there is power?

The pump is generally very close to the fluid reservoir so maybe you have one person inside the RV and the other person outside close to the fluid reservoir and have them press the button maybe be on a cell phone so you can communicate well and then you should be able to tell if the pump is running or not if the pump is not running you need to put a voltmeter on the pump terminals to determine if it's getting 12 volts when the button is pushed if so the motor is bad if not you have a loose or broken wire

Washer pumps are rather noisy, so you should be able to hear them if you follow pplwizard advice.

Also check the hoses from the reservoir (pump is inside) to see if water is squirting out somewhere besides on the windshield. And disconnect a hose to see if water squirts out the end (clogged sprayers or hoses are not unusual).
