I just ended up buying a 2015 3.6R Legacy and a few days into having it, the shifter bulb burned out. Now my warranty only covers the power train for free and everything else has a $100 deductible which I would rather not pay to get a bulb replaced.

 

Anybody have any ideas on how to replace that bulb? I'm assuming it's a separate bulb since P, R, N all light up.

Assuming it's an actual bulb and not an LED, best bet is to verify the bulb is actually dead. M-D means what, manual-Drive? If it's some sort of newer manual-shift auto or something, and the switch is in the console, maybe check if it's sticking. A previous owner might have had a coffee spill or something, or maybe a connector is loose, etc.
