Driver Door Window not staying down while door is open

[msullivan]

Hello,

 

I have a 2006 997 C2.

 

The door window drops 1/2 inch when you pull the handle on the inside or outside of the door when it is shut.

 

But when the door is open the window does not stay down the 1/2 inch so when you shut the door, the window hangs outside the rubber seal and you have to tap the handle to make the window drop underneath.

 

The passenger window works perfectly fine so I am assuming its not the battery reset issue a few people mention.

 

What is the problem? Is the the door assembly? If so can someone point me to a website for the part i need?

 

Thank in advance

Matt

The most likely cause of this particular problem is inside the door lock assembly, inside the door.  It's either in the circuit board or in the microswitch in that assembly.

 

There are a number of soldered connections on a small circuit board inside that door lock assembly which can crack and cause the exact problem that you have described.  The soldered connections on the circuit board can be reheated and re-soldered for a good repair.  The microswitch usually can only be replaced but Porsche does not sell that microswitch bi itself, only the complete assembly.

 

To definitively determine the cause you will have to remove the door panel and peel back the waterproof covering and then remove and test the door lock assembly.

 

Here is a photo of my door lock assembly ('97 Boxster), yours will look very similar.  The circuit board in question is inside the large white plastic housing and the soldered connections that usually crack are the ones that are on the edge of the circuit board, where the connector is attached (near the top left corner of the photo).  The movement (from its weight) of the connector is probably what causes the cracks.

 

 

There are a lot of posts on the microswitch issue on this forum.  Do a search here and you'll get a better idea of what you are dealing with if it turns out to be the microswitch.  

 

BTW, to see the cracks in the solder you will need a large magnifying glass.  They are almost microscopic.

It won't cost you anything to inspect the circuit board or to fix it if you are good with a soldering iron before considering the expense of a replacement door lock assembly.

Hello,

 

Thank you very much for your detailed reply.

 

I have had the mechanic remove this out of the door to inspect and it was in fact the micro switch broken.

 

I have ordered the complete door lock assembly off Ebay for £50 including next day delivery for a good condition, fully working used one. Porsche quoted £180 for this part but said it will take 10 working days come.

 

Will be having it fitted tomorrow once it has arrived.

 

Thanks again for your information
