Hey there, so this is a little long post just to explain and hopefully ya'll can teach me a thing or 2 since I'm young and wanna learn to fix this myself.
Ok so it all started when I hit the brakes, the parking lights (and dash night lights) would come on. Also when the lights were turned on by me, cruise control would not set (as if car though I was on the brakes) and the ESC OFF light would comme up after 5 mins of driving. So checked the fuses they look good. Then I checked my tail light brake bulbs. Took them all out, issue went away. Had one that was different bottom plate and the filament kinda look broken a bit in it. Plug them back in another way, now my bottom right brake light (which is that different and chinesium one) would always be on. So I figured I ordered a whole new set of bulbs and I went with LEDs to be more modern and now the only issues I have is the third brake light has like only 6 led that are always lit on and now my cruise control never sets and same issue for the ESC OFF light which now also happen even when lights are off.
So now my question is, what the [censored] is up. Is it because I got LED and should I try the OEM bulbs and see or at this point it's definitely a grounding issue?
And if it is a ground issue. How do I start diagnosing? I know how to check if the ground is bad with multimeter, but how do I start learning to find where the ground in the car are, and which one should I find and etc.
Hopefully you have any inputs would really appreciate it thanks!
Here's a video of how the brake lights are acting now, look at the third brake light.
