99 with a 2.5, ax5, np231. The part time light dosn't turn on when I engage the 4x4. I know the 4x4 works so it's either the bulb or the switch on the t-case. Any idea's? and if so, how hard is it to get the the bulb? The switch is easy but I've never had to change a dash bulb in it yet. Any idea's would help.
