I have been reading a lot on diff forums about a prob i am having with my trooper,4x4 light is on, batt light is on, and brake light is on, also the A/C and heat dont work. I am finding a lot of owners of 1996 troops are having the same probs, My alt tested out fine and have a new battery and new batt terminals, doesn't appear to be anything wrong with alt harness.I know for sure that i have one bad A/C relay, but that is the only problem i can find
