well not exactly the light, but the illuminated logo for the seat heater doesnt light up at night. is the fuse right underneath the button or is it in the fuse box? thanks.

 

not 100% sure-but I think there is a light blub under it. The driver's side on my tsx has been out for a few years.

 

like nj said, it's probably the bulb. common problem on our TL's...

gotta replace the bulb. i would replace ALL the bulbs while you're in there...so that you don't have to rip apart your console multiple times a year.
