    My passenger window keeps dropping right down when opening the door instead of just dropping a bit . And when you shut the door it goes all the way back up again.

    probably a common problem , and clue what it is ?

    micro swith?

    Micorswitch on either the door handle or motor yes.

    Take the door card off and check and bend the microswitch contact arm first and check with a multimeter.

    You may struggle to get to the door handle one so you will probably have to remove it....so at £35, you may as just put a whole new one in first.

    It's definitely the microswitch by the motor, there are some good posts on the US forum about it.

    Check this micro switch and cam is secure in the below, this is what stops the window on the dip function. All behind door card.

    Had the exact same on mine, a bit of contact cleaner 4 years ago and it is still good.

    The handle micro switch must be okay as the window is lowering when operated
