NBS LED A/C Control help?
I tried to attempt the LED switch a long time ago and had a problem with my A/C. It would never light up. Today I took it apart and moved the top rightmost led and boom, two of them lit. I re-soldered it and now it works normally, but the rest of the LED lights will not light up. It seems that the way this circuit board is built that they are chained together. Does anyone know which bulb I should try and fix next to make the chain continue or have any tips on how to figure it out?

Also check your solder joints close, if you moved one and it worked then sounds like you didn't solder it well enough, either that or the bulb itself is bad and if that's the case others may be bad.

While the 5050 chip can be used in single color applications, i have found the 5050 LEDs to be better for the RGB and the 3528 SMD LEDs in high density better for single color applications.
So basically just take the strip and cut out 5-6 leds and make a half moon circle the best you can, and find a way to attach them so they stay as tight to the board as you can get them, it’ll make the light disperse better and avoid having hotspots. For the center sliders, I used white 3528’s and just fit them inside the slider and made shields out of black hard plastic so I didn’t have the white bleeding into the other sides.
IIRC I tapped into my trucks parking light relay and ran a fused line directly out of the module and cluster. So I didn’t have to worry about burning up power to the leds. I forget how I made my dimmer switch still function though. I still have my full range of dimming for all the interior lights. I’ll have to check out how i did that again

x2. If you go the manual soldering route, make sure you plug in the unit while it’s still apart, and use a multimeter to find which posts are +/- and clearly mark them. Then use a 12v source to see which orientation your led needs to be and bend the postive leg on the led (or flag it somehow). It’ll save you a lot of time
