Window switch LED conversion, now no power for switch lights

[drdave81]

I was changing all my switches over to LED per ScottyBoy's thread. I did the driver master switch last and went to hook it up no LEDs came on. Double checked that I soldered everything, looked good. Took a test light, with interior lights on, and no light between the brown wire and black wire. I didn't see a fuse that would indicate it's for the switch lights. Windows and power locks work fine yet, just no lights to the switch. All other switches on other doors light up fine. Any thoughts, am I missing something obvious here?

Perhaps the polarity of the LEDs?

Turns out the cheap LEDs I bought were a mix and match of the resistor being wired to the wrong side. Got them all wired up right and now they work. Lesson learned, don't buy cheap stuff lol.

As @Fless stated, LEDs have a specific electric current flow polarity, unlike incandescent bulbs. Unsolder the LED, reverse its connection leads, and temporarily re-connect using jumper wires. If the LED then lights, you've solved the issue, and re-solder the LED into the connection with the polarity that lights the LED.

Yeah I know the polarity of them, just turns out some of these were presoldered incorrectly. The first few were fine and I didn't check each one
