Congrats on the acquisition - I hope. I'm 5 days into 986 ownership and attempting to resolve the same issue - windows are in the up position:
1. Windows dutifully perform clearance drop when opening/closing door.
2. Windows do not perform clearance drop when operating top latch, or opening/closing the top.
3. Center console switches will not engage windows.
All this in concert with no interior lights or door lights. I've checked all fuses including C3 and D1. I did push what I think to be the micro-switch button under the top latch with no reaction from the windows
