4x4 not working!
i'm sure someone here has been through this but i can't find the same problem in here when i search. when i shift my transfercase into 4hi or 4lo it won't go into 4wheel drive. i know the transfercase works because in 4lo i get 2lo, just no front wheels turning. when the truck is running and not in 4x4 i removed the connector to the vacuum motor on the axle and the black hose gets a good vacuum. from what i know, this is how its supposed to be. when i shift it into 4x4 the red hose should have a vacuum and the black hose shouldn't if i'm correct, but niether hose has a vacuum. i'm thinking it may be the transfer case control switch. anyone ever replaced one of these? i can't really see in there to see how it comes out. also wondering if i have to get bent over at a dealership for this part or if i can get it at a parts store.
