Window Switch LED Conversion (pics)
Following on from my IKE LED Conversion here is a DIY on how to change the window switches in your car to a different colour. This may have been done before, there may even be a DIY but i just did this as it was easy.

To remove the switches you need to remove the gaiter on your gear stick. Pinch it around the corners and lift it out to reveal the two screws holding the trim panel in place.


Remove the two screws at the back (closest to back of car) and lift it from here. There are 2 hinge like features at the front that as you lift will just lift out. Unclip the wires for your window switches and you end up with this.



The switch units simply unclip from the trim panel to give you this.

To remove the switch gubbins there are 3 little catches on each side to unclip. Shown here at the top of the unit. Just use a flat head screwdriver to pry it out.

This is what will come out.

Don't panic that the switch rockers have now gone 'limp', they are not broken this is fine. Also do not worry if a few bits fall out when you disassemble, this is also fine. The black plastic slider and grey rubber pads simply life up and off to reveal the LED and it's resistor. Note the orientation of the black plastic slider this has to go back the same way (won't go back wrong so you will know any way), the grey bit doesn't matter. Here is the LED.

Simply snip off or de-solder the existing LED and solder your new LED in its place. I used trial and error to get the anode and cathode (positive and negative) legs right as i couldn't tell which was which as the legs are already cut. Turn your cars lights on and just connect the switch to the wiring harness. If it lights up, bingo, if not swap it round.

Once that is done refitting is a reversal of removal.

***Tip - to put the switch back together rest both parts on their side. You can see on the side of the rocker (the bit you push with your finger) there is a grey plastic bit. Position this so that the bottom is level with the bottom of the switch housing (see pic). Being on its side the switches wont move while you slide the parts back together. This is where the orientation of the black plastic slider comes in. The bit that stands proud fits into the bottom of the rocker.***

The LEDs were just standard 3mm LEDs by the way.

Thanks man. I'm slowly doing different parts of the interior lol. Next up is the steering wheel, then the LCM, HVAC controls and then stereo.

Thanks for the feedback. Glad to see people think it's OK.

Looks good. May I ask what's wrong with the amber color?

Scott87 04-08-2010 06:58 PM

There was nothing 'wrong' with the amber colour. It worked OK but i just liked the idea of something a bit cleaner on the interior. I think once they are all white it will look even better. It had a lot to do with the fact i like to take things apart and put them back together and to make things unique. I don't know anyone near me who has a BMW with anything other than an orange interior :)

looks like good work...though i would never change to white...it looks like a honda now...but to each their own

Scott87 04-08-2010 07:13 PM

Haha i never even knew Hondas were white! I have in my tool kit red, blue, green, white, yellow, orange and..... ultra violet. I thought the UV would look cool, for about 5 minutes, at which point i may decide i don't like it. I want something different to the stock colour but dont know what would be best. Do you think i could pull off UV?
