Passenger side front window: sometimes driver side control will not control it unless I roll it up and down first with the passenger side control.

Passenger side rear: driver control will roll it down and up normally but sometimes the rear passenger control has to be pressed while driver switch is pressed numourous times quickly to get it to roll up.

Just some really quirky stuff driving me nuts for 12 months now.

 

Remove the switches and clean their contacts. After age, they are known to get dirty (contacts). Use some fine grit sandpaper.

 

yep...especially the master panel

 

Ok, will do.

 

it is very easy to do...but be sure not to scrape them, just lightly clean them.
