The problem is the disconnect only moves when the far end hose is off. I pull this end hose off and tried to blow in it. It seems stopped up. Is this suppose to be a vent hose? The 4x4 light does not work either.
the 3rd hose runs to the vacuum switch on the fire wall and is what turns the 4wd light on. kinda sounds like you've got vac on both ports instead of one at a time depending on which range you want. if that's the case, it's probably the vac switch on the t-case causing the problem.
