I noticed this past week that the right front passenger window was acting up.
When I would go to put it down, it would jump sideways, then go.
Trying to put it back up sometimes nothing would happen.

I thought to myself, "oh crap, a bad switch, motor, or a broken tooth on a gear."
But not so.
My rig sits underneath a mighty huge fir tree that likes to dump pitch on the rig all the time.

When I washed the rig today, I guess the soapy water getting down inside the windows loosened up some of the sticky sap.
The window is operating as normal now.

So next time your power window acts up, try washing it first and see if it doesn't fix it.
The way mine was acting up I seriously thought it was something major.
Who would have guessed the window was just stuck from some of the sap.
