I added LEDs and a new head unit for my radio as well as took the center consul out and painted it. Once I put it all back together my speedometer RPM temperature and fuel gauges did not work as well as my warning lights. I tried all fuses dimmer switch unplugged head unit among many others I’m at a loss.

Have you tried putting the halogen bulbs back in and not the LED? I have seen LED lights cause all sorts of different issues.

If you take a look at this wiring diagram below most all these systems run through the body control unit and if you have LED lights it can through off the resistance readings through this unit and it will cause it to act crazy in other areas.

I would swap in the original lamps and see if these issues clear up. If they do then you will need to find LEDs that have built in resistors that match the resistance you original bulbs have, or add resistors to the circuit so that the control unit doesn't know it has LEDs installed.
