truck drives in 2wd but the 4wd service light is on. it still goes in to 4wd high and low dont know if its a computer problem or vaccum problem in the transfer case. if you have any info please post.

truck has hypertech programmer, headers, straight pipe exhaust, shift kit, leveling kit, and rebuilt trans dont know if any of these would affect it.
 
Disconnect the battery for 30 minutes and see if that takes care of it. If not your best off pulling codes to see what comes up.
