4wd

[Koolkev1]

Pretty sure 4wd vacuum switch on top of transfer case is bad...there is a male switch that receives 4 vacuum hoses. There is one strong vacuum line going into the switch, but nothing coming out of the hoses going to actuator. Vacuum tubes going along frame to actuator and actuator itself was new last year.

My question is, am i thinking correctly? Am I missing something? And how difficult is it to change the switch?

Thanks in advance!!
