I bought a 99 cherokee back in feb the 4wd part time light on the dash does not come on when I put it in 4wd so today I tore the dash apart and took the cluster out and the bulb is not burnt out but I switched it out anyways just to make sure then I tested it by putting it in 4wd still nothing, so im confused is there something I am missing? I would like to get this to work and you guys are genius lol so help would be great thank you
