Window not dropping when opening the door from inside (passenger)

[andyjoshi]

Car 2006 C2S

Issue - On the passenger side, when I open the door from outside, the window does drop down a little and stays down untill I close the door. But when the door is opened from inside, the window does not drop, and drops only when the door starts to open. Then stays down untill the door is shut, when it goes back up again.

Based on this scenario, and searching around here, i believe that the microswitch at the inside door handle is gone bad. I called the local dealer to order the microswitch. The dealer told me that 996 had 3 microswitches, but 997 has the inside switch integrated into the latch. So I have ordered the latch (about $180)

Can someone confirm if this is the case. Thanks a lot.

I also looked at Paul's DIY on microswitch, but that is for the outside handle.

I can't say for sure. Looking at the pic of the interior door trim in the parts catalog, there's no indication of a switch associated with the lever. I'm concerned that it might not be part of the lever, but rather part of the upper trim piece (where the window switches are located).

Maybe see if you see anything of use in this thread:

Thanks mxt_77, I looked at the great DIY from Clifton, but could not figure the microswitch location. What is this (arrow in the picture) for? I thought its the switch/sensor.

It is the door latch. Here is the DIY.

The latch just gives out with time.

Good luck.

Sorry I was slow to get back to you. I just now had a chance to go out to the garage and play around with it a bit. The part that the arrow points to appears to just be a rubber stopper to absorb the impact of the door lever. The smaller button below and to the left of that is actually the switch/sensor. You can test it by pulling the lever open a bit and pushing it in or releasing it. Of course, you already know this doesn't work, so that's the likely culprit. There's a protrusion on the back of the lever that should push that button in when the lever is closed. Verify that hasn't cracked or broken off (unlikely). Then just make sure that whatever you ordered from the dealer includes whatever that button is connected to. Looks like it must be contained with the "insert", which is the piece with the window switches, etc. I'm assuming it connects to the box from this pic that has the red connector plugged into it.

It might be worth disassembling the door panel though, just to see what's back there. Maybe you can source a switch independently, rather than paying $180 for the whole replacement part from the dealer..

Thanks Paul, the dealer said its the latch 9 out of 10 times, but I still think its the switch/sensor at door handle. Marcus, you are right, I did the disassembly. Here are more details along your line of thought.

Here is the picture of door panel. Solid arrow pointing to the plunger, which pushes on the microswitch.

(removed from the door)

Following picture shows the reverse side, arrow pointing the location of the plunger. Red arrows point at the connector release tab and the tab below to release the module itself, note the part# 997.613.156.03

Following picture with the module out and arrow pointing the plunger location hole.

Front of the module with arrow pointing at the plunger. The white microswitch is visible in the right picture

Following picture with the module front and back separated by releasing the tabs circled in red.

And finally the plunger/lever out and the arrow pointing to the microswitch itself, which is part of the power window switch module.

I did not get a chance to check if the microswitch itself in faulty. Next I am going to check with the dealer on ordering this window switch module and test if this resolved the issue.

I may have lowered the picture quality too much. Let me know and I can upload better quality pictures.

Awesome. Thanks for the follow up with detailed analysis & pics.

I found a link based on the part number, and it looks like that switch module is about a $40 part. That's much better than the $180 you were originally quoted.

Good luck! I hope that replacing this part resolves your issue.

Issue fixed!!

Replaced the door switch, and now the window drops a little as soon as the inside door handle is pulled. Here is the analysis.

The design of the new version of door switch part has been greatly improved. Note the part version 997.616.156.05 A05. This is defferent number than original, but fits perfectly.

Details of the improved design

New switch assembled to the door trim.

Reassembled the door panel in reverse order as per the orginal DIY.
