New Battery Cable, Windows and Top not Working

[AviSalem]

Hi All,

I changed one of my battery cables that had completely snapped off from where it connects to the power distributor. After putting a new cable on, car starts up fine, door lights and interior lights work, radio, door lock, air conditioner all work. The windows will drop down and go back up when I open and close the doors, but will not operate from my switches. The top will not do anything either now. I tried turning and holding the key in the door in the unlock position to see if the windows would drop like that, no such luck. Any ideas? I completely disconnected the battery and connected the two cables together to discharge the car, and reconnected after 15 minutes to see if it "Resets", nothing changed. Any other advice would be helpful, I checked all the fuses, thinking it was a fuse problem, they are all good. Even tested the voltage on C3 and D1, both good. Please help!!

I do know that if the power is disconnected from the car, the power windows lose their reference point for the closed position and need to be re-initialized. We have info on the initialization process here: 986 Window Regulator Replacement - Pelican Parts Technical Article. Maybe try this out and see if it resolves your issue. Hopefully some other 986ers will come in with some advice for you as well.
