Looking for help! When the ignition is in gauged my brake lights are always on. I have changed out brake light switch twice, replaced control board in right rear quarter panel, as well as new tail lights. Any ideas?
 
Is the 3rd brake light on also and what year

I have had the same led tail lights previously for 6ish years.
 
When did it start happening?
 
2 weeks ago , had my water pump replaced and mechanic pointed it out.
 
So nothing was added to your truck say alarm, radio or programmer etc...

My guess is check pedal brake switch & wiring to wherever it goes which I think is body computer.
Where did you buy switch? Is it OEM part or Dorman etc?
 
Aftermarket radio with backup camera added many years ago. OEM switch replaced twice incase new one was bad order.
 
Try unplugging the tail light one bulb at a time.

They can go bad I have leds too. Let us know what happens, it is a good idea to check the wiring by the switch make sure there is not a short.
