Fixing BMW E36 Window Switch Light . . . DIY!


I’ve been looking for a way to fix my windows switches. The switches work just fine, but the problem is that they don’t light up at night. So, I thought they would look great if I could fix them. I did a lot of search for information about how to do that, but all I could find is one solution that is to replace my switches. Of course that was an option, but I wanted to fix the problem myself because I thought it would be very easy and I would have a chance to spend more time with my beautiful babe (I hope my wife doesn’t hear this :p ). Anyway, This DIY (Do It Yourself) will definitely help you fix the window switch light problem. I hope you’ll find it useful.

First, you’ll need to pull the switch out of the center console. You can do that by simply removing the gear boot and pushing the switch from below. After that, unplug the light wires attached to the switch. Then, use a flat screwdriver to remove the button cover. It’s very easy, but you should be gentle with it in order not to break it. After that, you’ll be looking at the switch which should look similar to this:

This orange or amber light bulb is what needs to be replaced and that’s exactly what we’re going to do. To get access to that bulb, we need to remove the green plastic that is attached to the switch bottom. Using a flat screw driver, push these carefully to remove that piece.

And on the other side as well

Now that the green plastic piece is out of your way, you’ll be able to see the electronic board that is holding the switch buttons and the light bulb.

Push the board to remove the black plastic case as well. Be careful not to break anything.

Now, we have access to the board itself. This is the light bulb that needs to be replaced.

There’s a plastic piece that is used to hold the light bulb. You should remove that carefully while trying to get the bulb out. Remember to be gentle with it.

This is the light bulb that I’m going to use as a replacement for the original one. Unfortunately, I couldn’t get the part number for it. Anyway, the light bulb should be:

1. As small as possible in order to fit inside the white plastic base that we removed previously.

2. It should not have a strong illumination, otherwise, your switches will look very odd and they’ll start to heat.

3. These bulbs give a yellowish color. You may want to use your wife’s or girlfriend nail paint (red preferably) to change its color to amber (orange).

Using a soldering iron, you can put the new bulb instead of the old one. Don’t forget to put the plastic white base again before soldering the new bulb.

Put the board back inside the black plastic case.

Reattach the green plastic base to the switch.

Put everything back as it was when you disassembled the switch.

Now, connect the switch to your car and test it. Make sure everything is working fine. I know I didn’t paint the bulb using the red nail paint because it was my first attempt. After I saw the result which is shown in the last picture below, I decided to repeat the whole process again and paint it with red.

This is the result I got after using the yellow bulb without painting it. I’m sure you’ll like the switches more if you paint them.
