Window Lock Is Not Working Properly?

[johnsonjf]

Hey guys thanks for taking a look at my post. I have a 2007 NBS Silverado 1500 ext cab with a little over 2,000 miles on it. When I turn on the window lock, it will lock the back two windows but not the front passenger window. Is this a feature or is something wrong with my window lock? If it is a feature is there any way I can reprogram it to lock all the windows? Any suggestions are appreciated!

Below is taken out of the owners manual. It appears that they are operating to specs. I did not find any bulletins to change the function.

 

 

 

Window Lockout

(Window Lockout): If your crew cab or extended cab vehicle has power windows, the driver's door power window switch has a lockout feature. The lockout switch is located in front of the window switches. This feature prevents the rear windows from operating, except from the driver's position. Press the switch to engage or disengage the lockout feature. An indicator light on the switch will come on when the lockout feature is engaged, and will go off when disengaged.
