This may be related, my driver side brake light went out recently, only the driver side. My first fix was to swap bulbs, I got LEDs because I figured that would be an upgrade.
Put them in but that brake light still doesn't turn on, however it does light up when the truck first starts up just not when I press the brake pedal. I thought this was weird but then also noticed my driver side headlight blinker/running light does not light up at all either.
Are these related and/or perhaps its the light switch? I wanted to check on here before I ordered any parts and had to send them back.
