Hello everyone, I tried searching for certain images which would answer my questions, but unfortunately I could not find. If any links can be posted which will guide me in the right direction, even in terms of replacement, I would appreciate it. I'm trying to determine which interior lights have burnt out on my truck (if they exist) and will tackle replacement (OEM halogen, not LED). 1. Gear selector bulb (this I know exists, but stopped working). I think I have a good handle on replacing this one. 2. On the drivers window switch, the window lock button does not illuminate (all others on this panel light up), I assume I have a dead bulb on this particular switch. 3. Are all the buttons on the steering wheel supposed to light up? (I have voice command / NAV). 4. Headlight switch, only the one small light on the dial lights up, are the other symbols around the dial supposed to light up? I believe that's all I was curious about with respect to interior illumination. Thank you in advance.
