Power Window not working

Question

This past weekend my power window in the drivers door of the motorhome stopped functioning.  Fortunately it was in the "up" position.  It is a 2005 Winnebago Voyage with a Workhorse engine.  (W22)   A few days earlier a quick rainstorm came in the open window and the controls for the window got wet.  The window did close and seemed to be normal.  Now it will not work after several days of dry conditions.  I was hoping it was just a fuse.  After looking at the owners manual for a Workhorse engine I could not find a fuse labeled for the power window.  Has anyone had any experience with this issue?  There are three sets of fuse locations within RV.  One in the coach section another under the dashboard and the third located under the hood in the engine compartment.  Any help with this would be appreciated.  Thanks!

Do the other windows work? If not, check that the window inhibit switch is not on.Carl

Don't know if it is the same with Class As, but our 2003 Chev truck is on its fourth passenger side window regulator. (Makes the window go up and down)

For no apparent reason, every so often it just stops working. There is a circuit breaker for it, but it seems the wires just jam up and that's that.

You have to take the inside of the door off and replace the regulator (you have to get that at an auto parts store) There are youtube videos to show you how.

Lots of bad solder connections (cold/cracked) in that kind of stuff. They last for a while before failing.

Try rapping on the control fairly hard with your hand or even the blunt end of a screwdriver. (seriously!)
If it starts working, you have solder issues. I good solderer can identify the cracked joints and reflow them.

FWIW, most (all I have seen) PW swtiches are totally protected from the rain. The part you touch forms a roof over the actual opening which has a curb around it. You have to take it all apart to see the construction. You can litterally pour a bucket of water over most of them and none will get inside to the actual circuitry.

Thanks to everyone for the good information and advice. There is only one power window in the coach. I should also have mentioned that the power window motor failed in the very first week after I purchased the motor home twelve years ago.

There are many videos on YouTube. Could the poster identify which one he was referring to in his answer to repair the regulator?
Thanks again.

The regulator is two tracks with the crossed wires and the motor on one track.  It is all one part that you buy. (Note how they hold the window up in place!)It is a PITA long job so start early on a day it is not raining.https://www.youtube.com/watch?v=Eb2WYXiV3dk
