Hey, new here just need some advice and help have a ford fiesta mk6 I’ve got an electric window problem l, so I can move my passenger window down but not up using the passenger switch but I can’t control the passenger window from the driver switch just nothing I’ve tried replacing the switch and nothing it’s like there’s no signal from drivers side switch to the passenger window and help would be appreciated 

Check for water ingress or corrosion of the connectors on the Body Control Module (BCM)

So is the window stuck down ?

Assuming this is a 2002-08 Fiesta:

If the window is stuck down, then it may not be the driver switch, but could be the passenger switch, a wiring or motor fault.

Driver switch controls go through the passenger switch, so if there is a fault in the passenger side, it may stop the signal from the driver's side getting to the motor.  Switch is the easiest "first look".

The Haynes manual has good diagram, with a meter, or a test lamp, you can check for 12V and buzz out the switch, before you dismantle the door.  I had a stripped gear wheel on my 2007 Fiesta......
