Global windows working on front only

[wercsje1]

I finally got the global windows to work on my 2021 Max XLT. However they only work on the front windows. I know the back one should be going down as well at least according to some of the dealership videos that show this function working when global windows is activated. Has anybody had any luck programming the back windows?

What dealership videos? Don’t think you have the ability to turn it on for the rears. I honestly can’t even remember if it works for our limited, it is 2 hours away, otherwise I would check. My 21 150 it only does the front.

If you watch all windows go down. Our 2019 Chevy 1500 did this with allwindows, cooled out the inside really quick, nice feature. If it only does the fronts then no big deal.

I only could get the fronts to work on my 202A ‘19 XLT as well. Maybe the limited/Platinums have a module we don’t. My reasoning for living with front only.

That video is a Platinum…so yeah, probably not going to work on your XLT.

The XLT’s don’t have one touch up or down windows in the rear. The upper trim levels do. I think this is what prevents the feature from working on the rear windows. If memory serves me correctly, the XLT’s have different rear door modules, rear door harnesses, rear window motors, and rear door window switches. The drivers door window switch is also different. There could be other differences.

I believe you are 100% correct.

My 2021 XLT w/202A does have one touch front windows, but apparently do not have the global open windows option. Wonder if assembly date of 7/2021 has anything to do with it...??? Would love for this option to work.

Yes, you have to have the one-touch windows for all 4 windows for the global feature to work on all 4 windows.

If you have One Touch up/down, those can be programmed using FORSCAN to global open/close. You have to use FORSCAN to add the option if you don’t see the option in Sync.
