The plastic tarp divider is completely gone. It helps keep dust and moisture out of your door windows and electronics. It was missing when you pulled your door off. I'm assuming it's been taken off before. Usually you can put them back on with The adhesive. that's still currently there.
Hello. Thank you for posting your question. Usually, it it the drivers side door switch that it goes bad. However, you can disconnect the one switch a the time to find the one with the problem (it is easy if you have a scanner to look at the body control module). Keep me posted.
Well I made a mess trying to do this and still can’t change the door jam switch. I have to attempt to get it back together enough to get it to a dealer.
