I had to install a new battery into my 996-4S and everything works great except for my windows lost the ability to automatically go down when button is depressed. If I hold down the button it's fine. Is there something I have to perform with the new battery? THanks..

 

I haven't heard of that b4. Try resetting the window switch by holding it down for 30-40 seconds after the window has lowered. Do the same with window up. See if that helps

 

Yes, it look like memory was lost. Do it that with the door closed.
