My power top stopped working.

My Z3 has been in the garage undergoing a few upgrades for the trip to HC (installed a new head unit with iPod adapter and hooked up my Sirius Sportster to it). I had the center console apart, so I might have pulled a wire off of the switch (I'll try to check that tonight). I checked the fuse and it is OK.
Is there anything else I should look at? It doesn't make any noise at all.
The good thing is, I can open the valve on the pump and opetate it manually until I get back. It is under warranty until April '06 so a trip to the dealer might be next!
Thanks,
Mark
Leaving for HC Wednesday!
