Headlight knob backlighting gone

[89Suburban]

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.

The mismatch would drive me crazy but glad you got her fixed

I didn't know there were even different colors and when I ordered it I saw no mention in the description or the reviews about it. So fk it 20 bucks I'll deal with it.

My interior all blue like your headlight switch.. Never saw my 4WD switch..

 

[89Suburban]

Dissected the switch and took some pics for you friends. As you can see the original switch had the blue backlighting as well.

Thank you 89sub!

Was hoping to make my upfitter switches blue, but my old park assist/traction control buttons use a surface mount LED..

 

[Doubeleive]

it's apparently common for the backlights to go out on the headlight switch mine failed as well, I suspect your 4wd switch has lost the blue covers inside

Nice job, man. Looks like those lights may be replaceable based on what we see on the back of the board. Would just require some soldering back to the board if a feller was interested in repairing the OEM switch. Cool dissection

It’s pretty easy to resolder blue LEDs in. I did -almost all of mine in my NBS.. another half finished project I need to wrap up.. I bought kits from Ebay, which contain the correct LEDs and some instructions.
