4wd Interior Switch not working

[gitnmybelly]

not sure if this is the correct place to post this.

My 4X4 switch in the cab doesnt seem to engage the 4wd. does anyone have any suggestions on what i can check or possibly fix in order to get it to work again.

thanx

what happens when you turn the switch? lights on the dash? ac blows from defrost?

mine has a vac leak so my auto hubs dont engage but the tc still shifts when i turn the switch

the lights will go on. but the 4wd doesnt engage. and no the defrost doesnt blow.
