There are 3 light bulbs that control the lighting on the shift base and are easily repaired by you at home or you can send me the parts and I will repair them for you for the cost of parts and shipping. I placed a discussion thread here about the items I am offering this repair service for:
View the shifter with the lights on so you can get a feel for how many bulbs are out and which location it is, viewing the below will assist in determining which one or ones are faulty. Bulbs required are 4mm sized "wheat" style with an approximate output of 100Ma. The blue covering on the bulbs tend to melt to the original bulb so getting replacements of those might be a good idea too.
1. Remove the shifter handle, then simply pull up on the shifter base to loosen it from the retaining clips and remove the electrical connector. Here is a photo of the bottom of the shift base:
2. You can also see the 3 white colored 1/4 turn plastic fasteners that hold the lamps. Take a flat tip screwdriver, insert into the slot on the white plastic bulb holder and turn 1/4 to release, turn the shifter upside down and tap it a little to get the bulb out. Just so you can see how it works, I opened up the covers to show the plastic pathways that direct the light from one bulb to multiple areas but you DO NOT have to take this apart to get to the bulbs, shown for education only.
3. The bulbs in this area are "wheat" style 4.7 MM 100 Ma and have a blue color corrective cover to make the light more white. The blue cover can be removed and reused but some are burnt onto the bulb from the heat so you might want to get replacements beforehand. It gets very hot, even the white plastic shows brown heat wear. The legs of the new lights simply go through two small holes on the bottom of the white base and solder on. Just unsolder the old ones and resolder the new ones in and trim off the excess leads.
4. I bought my parts from EBay but you can buy these bulbs and covers from many other vendors that sell lighting products.
5. Install is reverse of removal. Only thing to watch out for is when you reinstall the shift place, make sure the black plastic slider for the shifter is positioned properly forward and aft so that it slides properly and does not get bound up or breaks.
