RE: Shift indicator light?
There should be a light.
Remove the side panel on the driver's side of the centre console. There is one screw towards the front, at the top of the panel. Pull the panel out with a twisting action then pull it backwards. Remove the tie strap and clips from the heater unit. Remove the bulb holder and bulb.
Reinstall in the reverse order.
