2001 Jetta Power Door Mirrors

I have a 2001 Jetta 1.8T. The power doors mirrors only work intermittently.
Since I am basically the only driver they don't get adjusted much, but some
days they work fine and some days they don't work at all (either no mirrors
work, or both mirrors work).

I am guessing a loose connection and plan to start checking at the switch
and control and working back. I would appreciate comments from anyone who
has any comments or suggestions to help solve this.

Thanks
