I started having this issue when my middle instrument cluster would act fine until I'd turn my headlights on. then some will go down as if they were powered down while temperature gauge would show me that the engine is overheated. As soon as I turn the lights off everything goes back to normal. Is this some sort of a known issue? In any case, I was hoping someone possibly had it in past and has a resolution for it.

Sounds like a shorted wire somewhere

It ended up being a crappy connection on the contacts of the plug. Just fixed it by cleaning and greasing the pins with waterproof lube.
