JKuhl Posted October 6, 2020 Share Posted October 6, 2020 My 06 CHN has quad lock rears. The powerdivider is air powered and works like it should, and the icon illuminates on the dash. My individual switches/buttons for locking each axles differential do not illuminate and the rears obviously do not lock. I'm not having luck finding relays or a fuse for them although the decal is pretty well worn away on the fuse and relay panel mounted on the firewall. Anyone happen to know where these switched are powered from?? Thanks.
