Headlight knob backlighting gone

89Suburban · Apr 23, 2023

Some reason I lost the backlighting on my headlight and interior/fog light switches by not in the 4WD switch.

This really messed with my head last night driving in the dark I keep thinking my lights weren’t on.

Anybody have this happen and know the fix? Just a new switch?

I don't know how the circuits are in those. But, with that many bulbs being off, I don't think it's the bulbs. Have you pulled the switch out and checked the basics?

The bulbs are soldered to a board inside, just get another off Amazon. That's what I did anyway.

Well forget Amazon, too expensive, RA is $30.

Yes I did the basic research. And gave it a love tap / fist bump like you said. No dice. Pre-R&R exercise so I can replace it in a jiffy. Wish me luck.

I bought the same exact one in Jan this year. Feels slightly different, but works fine. I paid $22.90 w/ prime. Started return, but then canceled return.

The only issue I ran into is that it didn't appear to work right away. When went to change it back to OEM the next day so could return, it was working. no issues since. Perhaps ecu needed to be cycled?

Yeah I read that in the reviews.

Success.

The color doesn't match the other one. Was it like that with the old switch?

I honestly don't remember. I guess the old one had to be white because I don't remember the mismatch for sure. But I am fine with it being blue.
