windows auto-roll

I have a 2002 Maxima and the auto roll functionality for both the driver and passanger windows is behaving oddly. When I use the auto-roll-up, the window goes all the way up, then automatically goes all the way down. It keeps doing that - and I have to manually set it up slowly to close the window. Any ideas on what might be happening? The dealer wants to charge too much to diagnose - so wondering if anyone has seen this problem and if it can be self-fixed. Thanks!

The switch rocker auto actuators are broken, very common. Best bet is to just continue what your doing or purchase a complete power window switch unit(new or secondhand) and fit it yourself to save $$ (it will be big $$)
