The heater control lights went out

My heater control lights were out when I got my car. I was wondering how I can fix them and what I would need to do so. Just for clarification, this is what mine look like.
Thanks.

My first car!

P.S I fixed it haha.

i know i wondered what it would take to replace my 2010's unit, found the whole unit on ebay for $20. i figured if the lights went out, i'd just replace the whole thing. seems very easy on my year, unsure about yours. i wouldn't think it would be too difficult to get to.

edit:i just looked for yours on ebay...replacing the lights with LED might be the easiest/cheapest. however if you start with one set of lights going to LED you may find the slippery slope of wanting them all LED lol.

Where should I get them? Could I buy that whole piece with LEDs and just plug and play? Or is that not a thing? Haha

There are no mass produced LED hvac controls that I know of.
Not sure if anyone on here does the LED conversion as a service.
I did it on mine but have never done it for anyone else.
On NAIOA, which was the big impala forum back in the day, BBEngineer did a ton of them and he has some cool pics on his website, but he doesn't do them anymore.
For LEDs I get them at superbrightleds.com.

I think I used 5mm blue thru hole 360 degree but 180 degree will work as well. Don't forget the resistors as well. I used 1/4 watt 560 ohm resistors.

I hate to admit it, but I've never tinkered with LEDs for dash applications. How does dimming work with them (versus the stock bulbs)? I'm pretty sure they can be dimmed , but my fear is that, when some of the other dash lights are just right, the LEDs will be too dim or too bright.

BTW, I've replaced bulbs in the radio, instrument cluster and AC controls, but I used all stock type bulbs (incandescent). And that project turned out nicely.

Knowing that LEDs behave like diodes whereas incandescent bulbs are more like resistors, my first instinct is that controlling the various brightness levels might could get frustrating.

The LEDs hardly dim at all, that's the bummer. I did my whole dash at once so I didn't have to worry about different levels. That will be the problem with only doing one part, it definitely won't be even.
I haven't felt the need to dim my LEDs at night though. It's perfect for me.

Thank you very much might have some one install them since I don't know much on how to connect resistors

Not hard really.
Solder negative leg of led into negative hole in board.
Solder one end of resistor (doesn't matter which end) onto positive leg of led.
Solder the other end of the resistor on the board.
Done.
