Windshield Washer INOP

[Thor 25]

Windshield washer inoperable (INOP) doesn't work. Tank is full. Fuse is good. Ps hasn't worked since buying it two years ago.
Please advise

A 12-volt test light and a multi meter are an RV'rs best friend.
I would check that you have power to the pump and work backward from there. It could be a bad pump, bad ground, bad switch etc. Without checking for power in the circuit what you are asking is purely speculation on the forum members part.

Another thing to check and remember is when you buy the cheap washer fluid at the gas station and after you use it a couple times and then don’t for a long time( few weeks) the liquid part dries up in the nozzles and leaves a residue that will plug it up, easy to remove and clean with a small piece of wire, torch cleaning tips work well.
