I just picked up an '02 Xterra last week. All worked fine. This morning the driver side window took forever to go up. Like there was resistance. It eventually closed, but this was the first time it happened.

I don't like making uneducated guesses. It had rained the night before. I doubt it was the weatherstripping at the base of the window. But that was the first thing that came to mind. I had to keep pushing the window button up and down until it eventually closed.

By "switch" you mean the button that raises and lowers the window or is it more of a relay?

Do you have to replace the whole button panel on the arm rest or is it underneath the panel?

Thanks for your help.
