Recently I was having an issue with my speedometer not working. I removed the unit and took it out and unplugged and then plugged back in. All the issues I had before seemed to be gone

THEN...

I noticed the speedometer and gas lights illuminate and everything was lighting up and working fine but now the interior console lights don’t work. The speedometer illumination lights, tachometer lights, AC and heater control lights and basically any light that’s on the center console the illumination lights don’t work. The steering wheel controls backlight doesn’t work either. However, when I do an IP test on the tachometer everything lights up and works on the speedometer pin and backlit numbers. I’ve checked every fuse and everything seems fine. Whatever controls the backlights for the tachometer, speedometer and centers console light illumination seems to be the issue cause i think it’s controlled by the same thing. When I had everything working I had hooked up a scanner to it, ever since then now the lights don’t come on. I highly doubt hooking up the scanner did any damage, but coincidentally speaking ever since I did that the illuminated lights on the center console don’t light up when the car is on.

please help! I’ve looked up everything possible and still no luck. Just frustrating cause once I get one thing working something else happens. Seems to have many electrical issues

any suggestions are appreciated!

I originally thought when the speedometer wasn’t working and I had engine codes that I needed a new ECU, but turns out just replacing the battery and resetting the speedometer cluster did the trick. Now I have another issue of no lights illuminated when the car is on. It isn’t an issue when it’s daytime but at night it’s dark and I can’t see anything
