So I got some surface mount LED's to change the color from orange to blue & white for my car's interior lights. So I took out the volume control/track up and down/mode control on the steering wheel and very gently disassembled it to practice on and to see how it looked before I did the tach or HVAC. I had my friend who is very good with soldering take out the far right LED (far right in comparision to the place where the power clips in/above the resistor or diode) and solder in my new blue surface mount LED. I know I have all the right parts so thats no problem, but now for some reason even thought I took our just one LED and replaced it, the other two LED's dont light up. Any ideas? Thanks for any help!

 

are they all in the right direction? thats the only thing I can think of. I did all mine in my tC and a gen1 and gen2 xB and haave not had anything like that come up.

 

Yes all in the right direction, but I only replaced one so why don't the other two which I never touched not light up?

 

they're possibly in series, and u might have a bad LED, try a different one?

 

they are indeed in series...
if one doesn't light up.. all 3 won't...

and considering the one he touched was the one that was messed with... i'm thinking it's because he didn't do that one correctly.

 

De soldered the one LED and re-did it as best as we could and it worked! Looks great and can't wait to finish the rest. Thanks for the help Squall!!!
