To be honest, there isn't a lot of room in there to put in an LED on each of the 3 switches. I had the switch apart, the driver's door is an electronic carbon type switch( LED is a surface mount ), where the 3 others are mechanical switches and they take more physical space. I'm still going to try and stuff 3 LEDs in there somehow when I have time to attempt this. I ordered the smallest LEDs I could find.
As promised. I finally got the 3mm 12V LEDs today so decided to try stuffing them in the switch. Here is somewhat of a step by step. The switch assembly just pops out starting at the bottom with 3 connectors that also pop out easily by depressing a push tab. Power window switch is held in place with clips and easily comes out. Once you have the switch in your hands pull the rear door lock enable switch cover straight out.
One philips screw holds the back cover and six plastic clips 3 on each side.
You end up with this, be careful not to lose any parts when separating the 2 halves.
These LEDs aren't quite the same color and at 12 volts are really too bright and would be a distraction and annoying so I decided to place them in series so they would run at 4+ volts which should be bright enough to light the icons. Then I encountered my first obstacle, even these 3mm LEDs were too big and too round to fit in there so I decided to file them down to size so they would fit. Here you see an original and a modified version. Should have had a dark background but hopefully you can see that they are now flat and the lens has been also filed down.
These switches almost look like they were made to accommodate these LEDs
So wired the first one in...
Then the second with a test try with 6.5 volts each and still to bright.
Next all 3 LEDs are physically mounted and ready to be wired.
Wired the negative of the front passenger side switch to ground E- on connector.
Then ran a red wire from positve of LED FPS to negative of RDS LED, then jumpered the positive of the RDS LED to the RPS negative of it's corresponding LED, then the positive of said LED to B2+ on connector.
Now it was time to test the circuit in the Trax.
Well that all works, now to assemble the 2 halves and see if the LEDs do not obstruct any movement of the switches.
I snapped everything together and I have to admit it looks pretty good and the fact that the driver's switch is a different color is kind of a plus because it points you to it first. Tell me what you guys think... This whole job took me less than 1 hour ( It took me longer to do the write-up ) and I believe it is well worth it in my honest opinion and far exceeds my expectations. I'm happy with the result./forum/images/TraxForum/smilies/tango_face_glasses.png
I probably own the only 2016 Trax with all four switches lit-up.....
I was looking at this one from Digi-Key. It is a 3mm Turquoise colored LED but it is rated 3.5V and is very bright. I would need to connect them in series like you did and then add a resistor of 180 to 390 ohms in series with that to adjust the brightness and to drop the voltage to a safe level.
I am guessing that turquoise is pretty close to the color that is already there?
You will still have the only 2016 since mine is a 2018. I have not yet checked to see if the window switch is laid out the same as yours.
My 2016 Buick Encore has all of the buttons lit. I will check for interchangeability and report back. Part numbers are different but maybe connector pin out is the same. The internet hunt is on for information, lets see what I can find. Picture is of my 2016 Encore, Icons have a bluish tint like the Trax but my cell camera did a white balance before taking the picture. Ordered a switch last night in case they are compatible. If not I'll have a spare for the Encore.
2016 Trax power window switch GM#95188244
2016 Encore power window switch GM#13305373 ( BLACK )???
2016 Encore power window switch GM#13305374 ( COCOA )
Update: The connectors and connectivity are totally different, bummer but I will still take the new switch apart to see how it is lit up from inside and I will post pictures. Sorry for bringing your hopes up!
Received the Encore power window switch today. It has 4 carbon type switches similar to the driver's side switch on the Trax. All LEDs are surface mounted on the circuit board with no mechanical switches.
