Hi guys, I’m new here and hoping you guys can point me towards the right direction. I recently bought a 99 tahoe and noticed that the gear indicator bulbs only turn on while in PRN. Completely off during D321. I originally thought the bulbs could be out but then I started thinking there might be other factors involved that tell the bulbs to turn on… I’m starting to think it might be something else, since it’s D321 and not just a 1 or 2 bulbs out. Unless this is a very common issue. I’m also wondering if the gear switch on the transmission could be the culprit… any help or thoughts are appreciated.
