So today I woke up and I was bored. I'm really spontaneous so I drove to Radio Shack and picked up some LEDs so I could finally have all my window switches light up. At like 45 bucks a pop 6 switches was not at option (yes that's right, 1 of them is new, go me.) LEDs in hand I returned home to fun.
I removed the old LEDs (which apeared to be LEDs atleast) and put in my new ones. Hop in the car, hoping it will light. No such luck. Hmm interesting. Oh crap, a diode only lets current flow one way through it... eureka! Not quite.
Flipped it around no luck. Hmm what's going on. Grabbed one that I had put it and popped it into the socket just for old times sake. Light.... brighter light..... brighter.... dimmer..... (oh shit) pop, spark, "owe my arm!" Ok, so I got it in there right..... now what happened. The switch that came out didn't have a resistor in it......
Upon further inspection I was completely wrong. Two of my switches had been replaced with newer ones. Ones with an LED and a resistor.... Those weren't the ones that I opened first. The original ones used a tiny lightbulb with an actual filament. Weird. So I keep plugging and figure out the current to each socket in the car is 12.24-12.28 volts. Well that's way to much for those poor little LEDs, hence the resistor.
Measure the resistance on the resistor.... 750 ohms, ok good I'll head back to radio shack. 6:30 on sunday afternoon.... They're closed. Well tomorrow is another day and I'll finish it up.
For those of you thinking about doing this here's what you'll need.
Small little LEDs that look like the ones burnt out in your window switches.
750 ohm resistors for each LED (assuming you have all mini lightbulbs, if you already have a resistor just reuse it)
PATIENCE (and a steady hand)
Here's also some more of what I learned about the window system. I have no idea what everyone on the driver's express down switch is or how I'll do it. Figure that out later.
The switches in the rear (4 door model) are wired to the ones in the center counsol by the driver. Meaning that in order for the rear switch to work, the corresponding switch must be in place in the center counsol.
LEDs smells terrible when they pop/ burn out
I'll post some pictures and more info. Probably a DIY for others wanting to try this. Sorry for the ramble
