'89 Comanche Part-Time light stuck on

Hey Guys,

2 quick questions for you:

1.) As soon as I start this Jeep and get vacuum built up, the part-time light comes on and stays on. If I floor it, or disconnect vacuum from the underhood 4WD switch, it turns off. The underhood switch ALWAYS has engine vacuum at it, in 2WD or 4WD. Is it supposed to? When I first started working on it, the front axle disconnect was disconnected. As soon as I reconnected it, the light was on. The 4WD works normal, in 2WD, 4WD, and 4LO. Any ideas?

2.) The transfer case bezel shows a 4 wheel HI-LOCK, and a 4 wheel LO-LOCK. What is that? I can't find anyone who knows. It is just a standard Command-Trac T-case, is there something to these locks? Thanks!
