Did anyone by chance figure this out? Because I am having the exact same problem and any info would be greatly appreciated. Thanks

 

What year SS do you have ?
And by the “exact same problem” do you mean you’ve done the same diagnostics and replaced the same parts as the OP ?

 

Mine is an LS and yes same problem 3 windows wont work. I've replace the rap relay. All switches, window regulator. Trying to check grounds now, I have noticed that I'm only getting 5 volts to the window regulator and I don't understand where I'm losing the volts at.

 

Did you check fuse # 17 in the interior fuse panel?

Is the window lock activated?
FREE Owner Manual link in my sig.

 

Have check the both 30 amp fuses one inside the engine compartment and the one to the left of the passenger seat and also the window lock is not activated. I am getting a click from each window. When I'm trying to roll it down, it's like it's getting power, but it's not getting enough power.

 

You put this in the SS forum so I assumed you had a SS. I ask for the year in case we needed to check the wiring diagrams.
Again. What year is this LS ?

 

2009 according to the profile.

Sorry I'm new to this didn't mean to put it in the ss forum. It's a 2009.

 

Which window does work?
I suspect you think the switch supplies voltage to the motor. The windows are not analog.
The left windows ground under the driver seat; the right windows ground under the passenger seat.
Did any thing happen just before the problem started?
Here is a pdf of the wiring
