Okay so I have a 2003 GMC Sonoma ZR2 , my tail lights and brake lights do not work however my reverse light does and my third brake light at the top does.
then my headlights work and the turn signals come in but do not flash same with hazards they do not flash.
I have removed and cleaned all my grounds front and back of the truck
I have checked all fuses with a test light and upon checking them I realized when I remove my PARKLP 20A fuse from under the hood the turn signals and hazards will then blink but they allow the gauge cluster lights to blink as well and then once the PARKLP 20A fuse is put back they then go solid again , all other fuses are good , I also replaced my flasher relay behind my glove box
I can’t figure out how to fix these problems I hope someone has some direction for me ahaha
