Break lights won't turn off
10

Asked by Guru6PH95 Mar 30, 2020 at 11:59 AM about the 2005 Dodge RAM 2500 ST LB 4WD

Question type: Maintenance & Repair

When I press the break petal, the breaks stay on after after ai release the petal.  
When I disconnect the battery, the break lights go off and stay off when I
reconnect the battery.  The break lights will also go off if I pull the left trailer
light fuse.  The lights will stay off  when I replace the fuse and stay off until I
press the break petal again.  Does the wire from the LT fuse to the trailer
receptical pass through through some kind of a relay that might be sticking?

Brake pedal switch is out of adjustment or is bad. Try adjusting it first.

I can manually depress the new break petal button and it still won't turn off the lights.

Then it's a wiring issue or a body control module issue. You'll need a scan tool with live data to see if the BCM is receiving a brake light signal from the switch/harness
