Question type: Maintenance & Repair

ok guys I have a 2014 Z71 LT the door ajar
light came on for drivers rear door I took it
apart cleaned door latch (contact
cleaner/dielectric grease lithium grease)
put it all back together light went of but still
have no control to dome light when door is
opened and now the window on same
door will not work and also passenger front
window will not work I'm sure this is an
electrical/switch/relay issue can anyone
point me at a starting point dealer says it's
needs a door latch and a new wiring
harness in that door which I might would
bite on but they didn't take it apart I'm
assuming they diagnosed by computer?
But now with the new issues I'm unsure
any help would be greatly appreciated
since truck is 4000 miles out of warranty
and dealer wants 900 to fix just dome/latch

check the wire harness that goes through the body to the door it will be a black accordian boot.pull the boot back and look for any troubled wires.

Thanks I'll check that later.does all the power run thru the drivers foot switch to all windows? Just asking because it's the drivers rear door with latch and window issue and then the passenger front door with just window issue.


our chevy truck just hit 40,000 miles and the same thing is happening on the dash board the drivers side rear door shows open and dome light won't go off even when the door is closed firmly

sounds like a lock actuator issue.


What was the out come of this? My 2014 just stared doing the same thing. Door says it's open and rear window doesn't work. Sounds like this should have been a recall.

Does anyone have an solution for this. I just tore the door apart and changed the for the latch. No luck.

I have a 2014 Silverado as well with the same issue. Checked all the fuses, but no luck....still searching for an answer.

Had the same issue with my ‘14 Sierra, dash indicated that “Rear driver’s side door adjar” even though securely shut. I narrowed the issue down to a wire that had come loose from the harness inside rubber boot. It was a solid black wire that broke fee from the plug where the harness plugs into the body of the truck. Pull the rubber boot free from truck body to expose the plug of the wiring harness, there should be a hinged clip that flips up (purple on my truck) flip it up and the harness should pull freely from truck body. The wire in question was the second one up from the bottom, I believe it is one of the wires that supply power to the window motor, it is a heavier gauge than the one above it and had completely broke fee of harness. I was able to jam it back into place for now. This solved the issue with the dash indicator and dome Lights staying on as well as the window in that door now works. I plan on soldering it back into place when I get home. It is a relatively easy fix if you are handy with a soldering iron.
