help with auto window lowering (or whatever it's called!)

Recommended Posts

Sorry if this has been addressed somewhere and I could not find it.

 

I'll try to describe best i can.  my driver side "auto window lowering" feature (where it lowers 1/4 inch or so when the door is open) is behaving badly but only when opening the door from the outside handle; opening from inside works fine every time. here's what i know and all observations are made while opening from the outside handle:

1) no fault codes whatsoever;  6mo old battery and still tests fine;  i tried the manual-described "reset procedure" twice to no avail.
2) if i pull up handle slightly as if planning to open the door but not actually engaging the latch, the window cracks open in anticipation, as per usual/how the feature is supposed to work.
3) if i pull up handle just enough for door to open, the window cracks open and stays cracked until i shut the door, whereby the window will go back up to full closed per usual.
4) if i pull up on the handle full and open the door "normally" (see 4a below), that's where the issue is: the window cracks open but immediately goes back up despite door still being open.  the only variance to this is:
4a) if i pull up full on the handle but slowly open the door a few inches before opening the rest of the way normally, the window will stay cracked until door is shut, as it should
5) if window goes back up despite door being open as in #4 above, i can touch/toggle the actual door latch mechanism slightly which will prompt the window to crack open per usual and where it will stay until i shut the door.
6) the driver door latch mechanism in the open-door position looks slightly different than the passenger side. the drivers side lower portion of the latch (the little tooth/nub part that points upward) is more upward and visible than it is on the pass side which has that lower nub flush with the door. regardless of this, when i touch the latch slightly as in #5 above, the latch still doesn't have to look the same as passenger side despite the window now working as it should.

i feel that it's some kind of mechanical issue (i.e. which prevents a correct signal and/or preemptively sends an incorrect signal) rather than an electrical one because:  no fault codes, only one door is affected (the one mostly used and abused), and i can repeat the symptoms at will - i can do steps 4, 4a, or 5 above with exactly the same results.  every time.

 

maybe a cable that connects the outside handle to the microswitch?  or, how does the ECU know the door is open?  is it the latch?  

 

ideas?

Had the same issue. Door microswitch faulty and had to be exchanged. Search "door microswitch" in forums - and you´ll find at least this thread;

Driver Door Window not staying down while door is open

Allegedly; if You are good at soldering, you can fix it yourself.

thanks found some good stuff.  have no idea how i missed it the first time.  altho, is there only one microswitch per door?  if so, then why only the outside handle acting up?  i would think something wrong with the handle as opposed to the switch.  (i.e. maybe a short in the sensor between handle and switch, etc)

Each door handle (internal and external) has a micro switch. In your case the internal door handle (and the micro switch) is working fine.
