i took my dash apart this week end but i did not see anyway to remove the gauge face to replace the bulb. also it does not have a socket in the back for that.

i havn't had time to tear down yet it gets dark before i leave work and it's a 45 min drive home after that
i'll look for a socket(i hope it's that simple)
it's not detrimental but it's my ride and that makes it important to me
it's still on on the shifter it's self so i don't think it's a wiring concern
