my 95 tahoe will not engage into 4x4. when i shift the floor lever into 4Low or High nothing happens. there was/is no noise when this happens. it seems as though the problems is related to the actual shift mechanism and not to the transfer case. has anyone out there encountered such a problem, or have any suggestions.
I cant remember when the 4x4 engage changed from the heated to the vacuum deal. I bet its that. I'll look under my '92 and find the plug again. Mines still the heated version. They can burn out and the vacumm engage can also die. Sounds like thats what you have.
Check the actuator on the front axle; it is an elec. part with two wires running into it. It engages your hubs when you shift into 4x4. Also check a plug on top of your transfercase.
I had a new transmission put in and the guys bent the plug on top of the transfercase that also gave me a problem with the 4x4 engaging.
