Silverado Door Ajar issue 

Glad it was helpful!

You bet. Glad it was helpful.

Not 100% but I think it’s a different part number.

Does your dome light come on when you truly open the door? If not, I know my truck has an override button to disable it. Yours might be set to not have dome light on which is why it isn’t happening. I believe it’s all integrated in that same switch. And yeah it’s spendy.

@@West1134 I think I did disable it on the light control when it first started. So yeah, I'm fairly sure that's where my power draw is coming from. Brand new battery dead within 2-3 days. The alternator works fine. Something is causing the drain. I'm fairly sure it's that switch

Yeah mine was setting off the alarm or leaving the dome light on which was causing a drain. That part resolved all the issues.

@@West1134 Thanks for letting me know what I'm in for.

@West1134 I'm not much of a car guy so this video is extremely helpful, thanks. If I don't care if the car locks or not (which I don't) can I just unplug the latch or does that send something to the BCM that will continue this problem? Thanks again!

Problem is fixed. I had replaced my master window switch a while back with a cheaper Chinese one because the button pad was worn and that's when it started. There were a couple of other issues with the switch. Everything works great now. I will still buy cheaper parts because I saved $140 trouble shooting with the cheap door lock actuator and the Chinese window switch that had crappy electronics I managed to salvage the button pad from and got my old window switch working good again.

@@chewy98ta28 I have an 07 Classic Silverado. I added power folding mirrors but the right mirror adjust had been broken for a while and it did not operate the power mirrors. I bought a Chinese master window switch. It operates the mirrors fine but the truck thinks the drivers door is ajar. I though perhaps I jammed the latch during door panel installation so I ordered another and installed it. The problem is still there-Driver's door ajar. Do I need to try another manufacturer for the master window switch?

@@TheModelmaker123 I ended up putting my original MPS back in but I took the contact pad out of the Chinese MPS first and put it in my original and that took care of the door ajar issue and the buttons work fine except the door lock switch but I just lock it with my key FOB.

I don’t think this module would affect the symptoms you have. It did make my doors lock/unlock at times because the sensor was failing while I was driving (ie you shift into park and it locks the doors) but nothing to do with the windows.

I would think so yes. To my understanding these sensors relay the msg back to a body control module (BCM) which then interprets that to set off the alarm etc. My suggestion would be to find a wiring diagram and see if you can trace where the BCM is and test. Another possible avenue is a low battery. I’ve read tons on low voltage creating all sorts of gremlins! Get your batteries tested as a good first and easy troubleshooting step.

@@West1134 thank you

Honestly no clue on this one. My guess is if the latch mechanism isn’t registering with the BCM then maybe. But aftermarket alarms are their own can of worms.

@@West1134 yeah I want to think it’s a faulty security system but I remember testing to see if the factory one would go off and it didn’t, but the lights will still turn on when a door opens so I’m really confused on what’s going on

Yup!

I prob could’ve as the dome light would come on. However, since I drive my truck infrequently I keep it on a battery tender.

Link?

I didn’t find when I was looking the ability to buy just that actuator. I must have not used the appropriate search terms. Thanks for linking that!!

Yes. My issue was the door courtesy light stayed on plus when it would work I’d lock the truck then the part would fail again and set off the alarm since the truck (falsely) “sensed” the door was opening. Part resolved all issues.
