I've a 2003 Cerbera that intermittently (now permanently) doesn't want to wind either the drivers of passengers window up. The drivers side appears to have been corrected by a new microswitch, however the passenger side is a little more intermittent...
The window is currently half mast with the door switch, switching on and off the interior light. The window does not shift (or attempt to) with either door open/close, alarm enablement or the manual buttons. The window motor has recently been rebuilt.
I've opened up the window controller and noticed a liberal application of silicon, the silicon holding the top board in place (via the connector) has not held which in turn has removed the spacer holding the top board in place. However there doesn't appear to be any board damage and the interboard connector is still firm.
Any assistance in regards to where I should look next would be appreciated.
Cheers, Daniel.

Hi Daniel,
When the door is opened the reed switch (switch in the bottom of the door with the screw thread) switches telling the window module that the door is open which in turn drops the window to open and switches on the interior light. On closing the switch tells the module to close the window and starts the time delay on switching off the interior light. My drivers one has packed up at the moment not telling the module the door is open so you have to wind the window down on the window switches to open the door and back up again on the switch or on the alarm after the door is closed. If the reed switch is telling the ecu that the door is open permanently I think you will only be able to wind the window up to the drop height (door open height)on the window switch.
If you have changed the reed switch and set the clearance and the interior light is not switching on and off with door opening then it could well be a poor contact in the connectors in the door or a broken wire.

Window problems are almost always due to corroded connectors inside the door rather than a problem with the control box. No matter how many connectors you have found and cleaned there is always one you miss! Replace all the door connectors with properly waterproof AMP type one and there is a very good chance the problem will go away.
A faulty microswitch will not stop the alarm arming - but it can immobilise the window.

Hi Daniel,
the reed switch operates the door open close signal the micro switch is on the glass, they have different functions and operate differently. The micro switch is a pressure switch and is depressed by the window glass when operated, the reed switch is controlled by a magnet on the door shut.
If the alarm and interior light are operating correctly then the reed switch is fine. I think you are going to have to remove the door panel and check the connector for the motor, try powering up the motor directly with a 12v feed to make sure the motor is still fine, if it is then check what power and earth you have in the connector and work back towards the control box, there is also a connector inside the car behind the carpet in front of the door under the dash.
