Brake lights.

 

If the switch is good, there will be 12v coming out of it..
You say it is new, therefore it is likely good.
Therefore if 12v goes to the switch, 12v will go through the switch when the brake pedal is pushed.
This assumes the switch is properly installed and the brake pedal arm does not touch the switch when the pedal is pushed.

 

The break light switch is installed right yes there is power going into the switch but not come out when you press the pedal I plan on getting another new switch tomorrow

 

YOU have the under the truck bed next to the bumper of the wiring module .....corroded of the connectors ..
yes the forums are on the back lights ..
the brake switch of that pedal inspect it .. did the ABS codes ..

 

James, all I'm saying is

• if there is power going to the switch
• and if the switch is good
• and if the switch linkage is properly adjusted.

then 12 volts will come out of the switch when the brake pedal is pushed.

 

Like they used to say in boot camp, new doesn't mean good.

 

DId you try changing the bulbs or was that already a thought?

 

the 2006 GM and older is the light bulbs very good of the lamps .. GM is newer of the LED lamps is the damaged ...
