Radio and interior lights won't turn off...

[M1Gunner]

Excellent write up. I figured it would take way longer than 30 minutes!

Thanks!

Granted if someone is unfamiliar with taking the door panel off or unsecuring the door latch then it may take a little longer but it's still a some what quick fix.

Not sure if anyone else has had this issue but here's my problem and how I fixed it. I couldn't find anything online about this so hopefully this will help someone else out!

I drive a 2004 z71 Tahoe. I noticed that upon removing the key from the ignition then opening the driver door that the radio would continue playing music and the interior lights would not turn off. I would have to get out, close the door, open the door and then close it again for the anything to turn off. When I would open the driver door the interior lights would not come on. The door ajar warning wouldn't react... etc.

After looking over some wiring schematics I narrowed the root of the issue down to a component of drivers door latch assembly, the mini wedge switch. This door switch is an input to the BCM telling it that hey I'm open or hey I'm closed.

I removed the drivers door latch assembly which has three harness connectors that plug into it. The connector with the dark blue and grey/blk wiring is for the mini wedge switch. I disassembled the latch assembly and quickly realized the root of my issue.

Here is the complete latch assembly

Remove the metal strap from the top and the two small screws closest to the top

Nice write-up and great pics, dude. I've been dealing with this for about a month now and you may have just saved me $150. I really didn't want to buy a new latch! Perfect timing!

Thanks @ivin74 hope it does the trick!

I did the mod and my door lights are working again. Please be extremely gentle with removing the gear cover, i used a utility knife to cut thru the glue.

Thanks for the write up! I have been needing to fix this for a few months. I had already bought a used latch $50 on ebay before reading this so I cleaned and used that one. Now I got a spare. Oh well.

This should be in the tech section, maybe the admins can move it? Great write-up.

Just did this for my 2005 Yukon, however, it didnt help me. I still am getting the Drivers Door Ajar warning.
Looks like a RockAuto order for me!
Great write up and worth the time to just to make sure.
Thanks!

I turn off the engine remove the key and my radio will not turn off when opening the drivers door but if i walk back and open the drivers passenger door the radio will shut of as it should I will go your route and clean my contracts and see it that takes care of the issue. Thanks and good write up Sir!!!

Does anyone know if this procedure is similar for the rear doors also?

 

[Jason in DLH]

Will be trying this as the same thing is happening to me. Thanks for the info!

Give it a shot and let us know if it works.

Did the left rear door this afternoon. Worked out good.


Then I find out that these actuators are done by Dorman.

@M1Gunner, great post!
I know this is an older post but this just happened to me today on my 2012 Yukon....coldest day of the year! I go out to ck my car earlier and the battery is dead....dead, dead. Anyway I charged the battery, yes it's only 1 year old. So then the door latch got boggled up and so the door won't close. As I'm trying to figure that out, I work on it for several hours, can't get the latch to go back into the right position. I finally give up (it's dark out by now) I turn the car off and the gauge lights and radio stay on.d..I fiddle with it a bit and realize that's why the battery was dead/ I drove the Yukon a couple of days ago in the daylight, didn't realize when I did the radio and gauge lights didn't go off.
So, since tomorrow is a holiday and it's so fricking cold out I'll try to get into my mechanic on Tuesday or Wednesday. I don't feel like messing with it.
