[89Suburban]

I just noticed you popped in a link, thank you 89Suburban.

Good luck buddy.

Hello. I did not get too far yesterday, family/kid stuff. I did roll around under the right/rear side looking for a ground cable/wire. Couldn't fine one. I will look closer today. Wes, thanks for the clarification of the word "dirty" in an electrical schematic, I did not know that.

Free Tip Saturday: if you want to "tag" someone, either quote that person's post (like I did here), or use the "@" symbol and start typing the user's name. Then pick the correct one from the picklist of users. Finish typing your message.

If you don't do either one of those, your target won't be a sure hit.

Thank you. Test here.

FYI! Last night, I had one of my kids sit next to door, it is making a little noise in the RR door.

So there is power!? Jammed or worn out motor?

 

[201125004x4Sub]

OK. So today, my other kid did not hear a sound next to window motor (w/panel off).

I don’t know if I am doing this right, but I got no light, w/ignition on, trying this pin and the one next to it.

Any other tests I should do before door panel goes back?

I also tested the power on & the RR door switch.


thank you

What year are we working on, or did I miss that? Some of these within the same body style have somewhat different electrical systems.

Have the appropriate fuse(s) been verified as having power going through it?

 

[201125004x4Sub]

OK, I need to add a signature. It is a:

2011 Chevy Suburban, 2500, 4x4, LT.



I forgot, in my initial post, I said I had a lil' electrical b lackout when I went out to start it the other day. I did check the battery cables (look brand new) and the ground was a tad loose. I tightened it. I as assuming the window is a different thing.

Thank you.

I found a couple videos on this. ! read (Reliable sources? - Don't know.)

circuit board needs checking for crud?

This one says there is a circuit breaker on kick panel w/a fuse for passenger side windows. Can't be that one though, I think, because FR window works fine. About 1/2 way down, specifies 2008-2014 sub.

It wouldn't light up moving the switch back and forth?

 

[201125004x4Sub]

It would not. Checking driver switch now, because it is an easy test.

thank you

See if this helps,

Did you look at page 35 and 37 on this link?

 

[201125004x4Sub]

So clean under driver Switch.

Did not take apart, no dried soda or gunk.

 

[201125004x4Sub]

89Burb, great link. Inside incoming harness for switch. I did get power for going up. No power for going down.

Here is another link for another one. I am looking around page 641.

[201125004x4Sub]

Thanx!
OK, I think pg. 642 is right for RR and 641 is LR.

What the heck is that a drawing of? I see the ”BCM” for Body Control Module.”

 

[201125004x4Sub]

Just watched this video on BCM replacement on a 2007. Do I need to go to a dealer? I don't have a non-Apple computer.

 

[201125004x4Sub]

Enough for today, plugs & door panel r back on.

Thanx so much for the help today 89Suburban, you really helped me track it down!


BCM question here. If my BCM hasthis problem, can a dealer just reflash it and all will work? Or do I need to buy another one?

Thank you.

 

[89Suburban]

I'm surprised to see this issue on such a low mileage truck. The BCM stuff is above my education level.

 

[201125004x4Sub]

Beyond me too.
Thank you.
