I have a 2001 996 C4 Cab . I let the battery go flat after the car had been standing for a few weeks. I had installed a new battery only a few weeks beforehand. I knew there was a fair chance it would go flat so had left the bonnet latch open so could get to the battery to jump start it and managed to get it going ok. However when I powered the drivers side window down , I couldn't get it up again. I took the car for a 30 minute drive but it would not reset the drivers window. I put the car on charge to let the battery upto to full charge. I had the hard top on and seemed to recall that I'd had windows out of synch previously and operating the hood a couple of times got them working again. So a couple of days later i removed the hard top and operated the hood. First time the passenger window went down and and came back up again when the hood came back up, but the driver window didn't move (still fully down) . I did it again but this time when the hood came up the pass window stayed down . I operated it a few more times but neither windows are now coming up . Any ideas appreciated.

 

With the doors closed try placing the key in the door lock and hold it towards lock for 30 seconds. It should drive the windows up after a few seconds.
