    I have a few quick question about the rear sunshade blinds on e46 Coupes.

    I have purchased a rear electric blind for my 330 coupe, I will be fitting this on the weekend.

    I have no buttons to operate this. Currently there is only a 2 wire plug on the electric motor which is the same as the window motors.

    Ok... my question is do you need some sort of a relay unit or control unit to make it go up and down or do I wire it on a standard rocker switch which will reverse the poliarty(up/down), obviously once up you let go of the button and once down you let go of the button similair to the operation of electric windows.

    I want to put an over protect circuit on so that it doesn't burn the motor out, once any stress is detected the circuit should cut out.

    What type of switch is on the standard dash for this unit? I guess it is not a rocker switch... lol.

    Any help or advice would be much much appreciated.

    Many Thanks.

    Roller Sun Blind
    The roller sun blind is controlled by the centre console switch centre.

    The roller sun blind is operated by means of a push button in the switch centre of the centre console or via an external push button in the rear compartment of the vehicle (E38 Series only, optional extra). By briefly pressing the push button, the roller sun blind is raised and lowered automatically and the direction of movement is changed every time the button is pressed.

    Fault monitoring
    In order to avoid damage to the roller sun blind, the drive is monitored for blocking by measuring the current. The drive is considered to be blocked when the permissible motor current is exceeded. In this case, activation of the drive for the roller sun blinds is terminated immediately.

    A fault code is stored in the fault code memory of the switch centre in the case of a break or a short-circuit in the drive or line. In addition, the roller sun blind can be checked by reading out the push button statuses without activating the drive.
