Car: 2003 996 Cab.
Symptom: The fuse for the front power windows and the fuse for the rear windows will blow instantly when a new fuse is inserted.
History: The car was in winter storage and, though disconnected, the battery went 100% flat. I reconnected the battery and used a jump-start box and she fired right up after letting the battery pick up a little charge. But the windows rolled themselves all the way down and then (I guessing here) the fuses blew. When I replace a fuse, it blows even before I can get it all the way seated.
Also, when I got the car home I removed the battery and put it on a slow charge, so the car was essentially without power for 2 days.
I've scanned the car with a Foxwell NT-510 and there are no faults in any system.
I don't have any idea where to start troubleshooting this. I don't know where to find a wiring diagram to begin knowing where to look. I'm handy with tools and comfortable with electricity, but this has me stumped.
Any thoughts on where to begin?
After doing some research, I cannot find a clear solution to this problem. I have a 1997 Boxster which has a problem with the window controls.
If I remove the convertible top relay (double relay), both door windows operate as expected (proper drop when door is opened, auto drop when you press the window control, and full motion up and down).
When I insert the top relay (even with the top latch closed), both windows drop the standard 3 inches and the driver’s window will only go down. Once the driver’s window goes all the way down, it will not go up until I remove the top relay.
Any thoughts from the community?
I just resolved a window issue on my 2007 Porsche Cayman and wanted to post and help out anyone with a similar issue. My passenger side window was functioning normally except for when I closed my door the automatic window drop to clear the door seal was not returning to the complete up position and was staying down. The automatic up feature on the window was also not working. The auto-down feature worked and all other functions of the window performed normally.
So to be clear, when you pulled the exterior and interior door handles the widow dropped the 10mm or 1/4 inch it should. However, upon shutting the doot the window would stay down in this position and not return up. So....
I decided to do some research and came across the "latch micro switch issue".. I figured hey part isn't that expense so I replace the latch and the issue remained. After much more research, I came across a post about that issue being caused from a faulty door motor ECU. This IS the reason for the issue. After, disconnecting the battery, taking off the door panel using numerous videos and instructions from this site and others I was able to quickly replace the motor unit with a new one that I got on ebay for $120. The motor is easy to remove, 3 screws and then just pull the motor straight out and it will disconnect from the window regulator. Next, pop in the new one and you are good to go. Finally, the issue was resolved upon reconnecting the car battery and the motor auto cycled up and down and is now functioning normally. I wanted to post this as I am hoping someone else who does a google search for a similar issue will find this and save them hundreds if not a thousand dollars from taking the car to a Porsche dealer. The part number for the motor that I used to replace the current window motor was 997.624.182.06 replacing the original part that was 997.624.182.03

All of a sudden my passenger side door window will not go down all the way. It WAS working fine, no noise, and it drops a bit when I open the door and comes back up when I close the door...as it should. But all of a sudden will not go down all the way. Otherwise it works fine: Up and down, just it will only go down until it reaches the last inch or inch and a half, then stops as normal. The windows also work as they should when raising or lowering the top, but of course that pass-side window stops at the last inch or so.
So, where should I look, and in what order?

I'm having electrical issues with my 2000 Boxster S.
My windows drop when the doors are opened, but they do not respond to the window controls. They do not come down when the Convertible top handle is pulled.
The doors do not lock or unlock with the console button or the remote. I can only lock the driver door.
The defrost button does not respond.
I replaced the C3 and D1 fuses even though they looked and tested good.
I'm getting 13 volts (when the car is on) at the C3 and D1 positions.
I pulled the console and tested voltage to the switches and couldn't find any voltage between any two of the many wires going to each switch.
I replaced the module under the driver seat with a new one from Suncoast Porsche and had my local dealer reprogram the new one from the old one's data. The only difference is that my convertible top started working soon after that.
I read in other postings about SPDT relays that are just above the fuses, but I can't find any information about which relay would be affecting these components.
Any ideas on next steps?
