Hi,
My front passenger door window wasn't working.
We've removed to rim and found out the motor wasn't even there ...
Replaced both the elevator and motor and tested it applying +/- and it worked properly.
However when connecting the harness, the window opens (slided down but not up).
Tried to invert the wires and the window closes (slides up but not down).
Any idea ?
Wiil it be the passenger door switch ? The drivers door switch ?
Or the CPU on the annex drawing (from Haynes manual) ?

And can anyone check the correct number parts for replacement ?

Window Switch - Haynes

 

It's not function on driver side and passenger side ? if no it's the door module problem.

 

Seems like that is the switch itself. Mine have gone bad and would only go up after going all the way down. I have repaired them by cleaning the contacts in the switch itself. This is not something for the faint of heart though as it is typical Jaguar overthinking and making the switch unnecessarily complicated.
