Looking for some help for the next step addressing my window drop issue. Top up, pull driver side handle and window drops like it should, but when I release the handle the window goes back up and hits top when closing. Passenger side behaves differently and stays down when handle is released like I’m pretty sure it’s supposed to. My son and I replaced the micro switch at the door handle today and the behavior didn’t change. Anyone have any thoughts on what to look at next?

here’s a short video of the issue.

thx

 

You are correct thinking hte window should stay in the dropped position. is appears the outside handle microswitch is working correctly.

What sounds to me like it isn't working is the door latch switch. The door latch needs to be able to tell the system that the door is still open so that the window doesn't roll beck up.

 

Thx, that’s what I think it is too after doing a bit more research. The lock mechanism is like $100 for the URO brand. Can’t say I’m looking forward to the job, looks like a pain to get in there and deal with the connections. The micro switch on the door handle was simple.

 

I haven't had to deal with this yet on mine, so not sure what access is like, but if it were me, the first thing I think I'd try is spraying that micro switch liberally with Deoxit D5 and sed if that will help recover its functionality.

If that fails, I think ytill be headed down the replacement path.

 

Access isn’t too bad, it’s just kind of a not so fun job to do. can you spray the switch from the outside?

 

RL911 did you resolve the window drop issue?? I have exact same problem

 

not yet, but im 99% sure it’s the switch in the door latch mechanism. I’ve ordered a new latch and will be installing it in the next week or so.

 

I'm experiencing the exact same thing in my 2007 (987 cayman). I took the door latch out this past weekend and measured the switch in the latch and it appears to be working perfectly. There is continuity when the door latch is "open" and no continuity when the door latch is locked closed. Which leads me to believe replacing the latch won't help, but its worth a shot. Where did you order the latch? Looking forward to seeing if this solves your problem.

 

i bought this one

Thanks! I ordered one too. Hopefully that really is the issue. I read elsewhere it could also be in the window motor itself...but that doesn't make much sense to me.

 

It is the microswitch in the door latch that is causing this. I bought a genuine Porsche replacement door latch as I read that there is more than 1 version and there can be mismatches that can cause it not to work. There is also an article on rebuilding your door latch with VW door latch parts - which would keep the electronics and wiring correct. It will be interesting to hear if others have had good experience with the URO brand.

I took the door latch out and, with it out of the car and on the workbench, I closed the latch while measuring continuity across the door latch microswitch. There was no continuity when the door latch was in the "open" position, and then there was continuity when it was placed in the "closed" position. I tried it five or six times and each time got the same result, so I concluded that this switch is likely okay.

When I open my door, the window rolls down, but goes back up as soon as I let go of the door handle. So it makes sense that it would be that microswitch, but it doesn't appear to be.

 

could it be that even though the switch tests good, the mechanism isn’t making good contact when installed in the car?

 

Do you get the same behavior if you open and close the door using the interior door handle? If so, it is the door latch mechanism. It is the door latch mechanism that determines if the door is open or closed.

 

I can't imagine thats the case, because its the latch itself that I flip, and if that wasn't working, then the door wouldn't stay shut.
