Hello. Is there any way to repair or replace the small square red LED lights on the J gate shifter that note each shifter position? I was able to unsolder and resolder new light bulbs in, and those work fine, but I have two burned out red LED lights at the "D" and "4" positions on the J gate. Can these be repaired/replaced, or is the only solution to find another circuit board where all the red lights work? I didn't want to start digging around before I asked the group. Thanks as usual.

 

I sent mine off to Module Masters, IIRC. They replaced all the lights on the shifter mechanism with LED. I don't trust myself with a soldering iron.

 

They're surface mount components, so it will test your eyesight & soldering skills...

Worth checking with a meter that they're really dead?

Mouser has a good few options, e.g. something like this:

Thanks, that looks like the LED, or at least very very close. I'll have to get the magnifying glass out and see exactly how those things are attached and if I can even get to them.

 

If you've not attempted this kind of repair before, it's worth practicing on some scrap electronics first, or just take the board to a repair place. Pretty much any electronics repairer can do it, even a mobile phone repair place might have the tools.

First though do what Michaelh suggested and check they are actually dead and that this isn't some other fault.

You could also very carefully measure the voltage across the working LEDs to see what spec your new ones need.

 

Thanks, this is good advice. I had a scrap circuit board that I ruined previously, and I was able to un-solder two known working LEDs from that and solder them onto the non-working locations on my "new" circuit board. They still don't work, so I probably didn't do it correctly, or, as you said, there is another fault in the circuitry itself. I'll look into an electronics shop, that's a great idea, although not sure how they can test it without it being attached to the car wiring.

 

You can test the LEDs on the board with it out of the car, with a multimeter. Set the meter to Ohms range and measure across the LED, note the reading and take the measurement again with the leads swapped. One direction should give a high resistance and the other a low resistance. If you get the same each direction, then the LED is probably dead. Find a youtube video for better instructions.

You also need to bear this in mind if replacing the LEDs - they only work one way around.

 

Thanks, I'll try that out.
