Vehicle acting like it has interrupted electrical current, but it starts and rides normal.
1) Turning signal display delayed or frozen on instrument cluster, but if you look outside it working with normal intervals.
2) Windows stops 3 or 4 times on its own before completing opening or closing cycle
3) Electrical seats will stop several times on its own before completing forward or backward motion.
4) Windshield wipers have delayed start and will freeze and move again.
5) Back up Light flashing and sometimes completely quits working.
6) Cornering Lights (directional signals) always on and flashing.
7) Vehicle A/C fan will quit and starts again; electronic temperature display shuts off then start again in unison with A/C fan.
All flashing and acting don't have any specific intervals. It looks like vehicle is in electrical starvation mode.
I have replaced: battery under driver seat, (battery in trunk been tested normal), wiper switch, turning signal module and switch, head light assembly, All parts brand new from Porsche.
There no codes I can give from vehicle computer, because I have to disconnect battery ground terminal for overnight parking, if I don't battery under driver seat will be drained.
