Windows don't drop when the top is unlatched.

Hi All!

I've read through the forums and wanted to get a little confirmation before I order parts. When I unlatch the top to put it down, the windows do not drop their normal few centimeters. Here's what does work and what I've checked:

1) Both windows drop when I open their respective door.
2) I checked the fuses for the windows and all are good.
3) I pulled out the top latch microswitch and it was corroded a little on the two metal dots behind the clicking part of the switch, but still doesn't work.
4) I can't swap the top relay out because I don't know anyone else with a Boxster.

I'm thinking the microswitch needs to be replaced. Are there any other tests I can do to confirm it or should I just go ahead and order the switch?

TIA!
