Full time Light Flickering

[XJ_Matt]

It is flickering sometimes i dont know why and 4wd wont enable the front axle sometimes. Anyone have a diagram of factory front disco axle 4wd vacuum on cd they can post up. Thanks!

flickering light and problem with 4wd could be a cracked or broken vacuum line between the transfer case and the axle disconnect.
