Title: 4X4 indicator light
Post by: farmallgray on November 04, 2008, 09:32:25 am

My 4WD dash light isn't working. The bulb is ok. My truck is a 79 K20 with TH400 and NP203 t-case.
Where is the switch located, and are they known to go bad?

Access from the top by taking the boot off, or from the bottom easiest?
