If the driver's window becomes unresponsive , or one window button "works on and then gets stuck," or the lock button disconnects ... the problem is most likely with the master window switch assembly, as it is the most frequently used part and is exposed to moisture/dust/wear and tear.
This part is a set of window and door lock buttons for GM vehicles, which installs in place of the old switch as a direct replacement.

- “Cera Glass Buttons 2012”

The basic idea: Instead of changing wires or disassembling the glass motor, start with the most common cause: the main group of buttons .

Frequently Asked Questions
Does this part fit a 2012 Tahoe?
Yes, it is compatible with the 2007–2014 Tahoe, and it is best confirmed by matching part number 20835552 or an alternative number found in the description.
Is it right or left?
This is the driver's door assembly (left) because it is the "Master" and has several control buttons.
My car is a 2016/2018/2021 model… Will it fit?
We do not accept returns without matching the part number/plug shape. Please send me your part number or a picture of your old part and I will match it for you before you purchase.
Do you need programming?
Often no, direct installation when the part number matches (Plug & Play).
My problem is that the glass sticks… Is this the reason?
One of the most common causes is a faulty main button assembly. If the problem persists after replacement, then we should check the fuses, motor, and wiring.
Does it also work with door locks?
Yes, the door lock/unlock buttons are included within the same unit (depending on the category and equipment).
