Half dash lights not working

[SUBURBAN5]

But to test that. You would have to put some good bulbs in and see if it works or not

I know LEDs can play some electrical tricks

I was wondering the same thing. I’ll pull it out again tomorrow and see what all I can find. It’s just odd that half works and half doesn’t. Neither do the turn signal lights but are fine outside the vehicle.

Test it and see. Keep us posted. I've been wanting to LED swap my cluster but have other stuff pop up..

I've never done this swap, but keep in mind that LEDs are polarity sensitive.
A regular light bulb will light no matter what side gets positive or negative, an LED will only light one way. If one doesn't come on try switching it around, most dash lights I've seen will plug in two ways 180 degrees apart.

This. When LED bulbs don't work, always flip it 180 degrees. 99% of the time, it will work.

You cannot use an LED bulb for the ABS indicator. It actually throws a code on the ABS module for the indicator circuit lol. An LED should work for the Airbag indicator, but do you have the passenger airbag switch on? If it's off, that indicator will stay on.

I haven’t had a chance to mess with this yet today. I do not have a passenger airbag.

Flipped bulbs today. Turn signals now illuminate but that was the only change. I did notice that my headlight switch stays illuminated 100% of the time. I don’t remember that happening previously. I’m thinking maybe the switch itself has failed.

I could of sworn the headlight switch stayed on 24/7 but somebody on here said it turns on whenever you turn on the switch. Mine is original and the light finally went out years ago.... need a new one lol

My headlight switch is illuminated 100% of the time. It's been that way the 6 years I've owned it.
