Can anyone give me some help please I have fitted a good replacement motor and checked the fuses but still no rear wiper what's next ?

I would get the testers out and check the switch is working first. 2020 Porsche Panamera Turbo Hybrid (V FAST)

That's sounds complicated

The only way you're going to find out if you have voltage at the switch or the motor is with a set of testers i'm afraid.
If you have a set its quite easy.  2020 Porsche Panamera Turbo Hybrid (V FAST)

Ok so no live at the motor any ideas please

Lots of fuses control different areas of the system..

Fuses 27, 41, 53 and 10, It also has some input from the BECM via K bus so if the fuses are all there and the switch is working you may need some diagnostics or an auto electrician...  Pete
