I was told there were 4 different transfer cases and not all of them have it on there. Could it be the module or the switch on the dash? Could it be something else?

The encounter motor is moving. It seems like the front axle is not locking. Do you know where the transfer switch is on the actuator?
Expert:  Tim's Auto Repair replied 6 years ago.

yes..

 

you need to check the vacuum actuator under the battery....remove the vacuum line,check to see if you have a vacuum when it is running and in 4wd,if you do,the problem may be the vacuum actuator,,,if not,the problem may be the vacuum switch on top of the transfer case[this has 3 vacuum lines to it]

thanks

I have been looking for the vaccum switch on top of the transfer case. I can't find it. I was told there were 4 different kinds of transfer cases. Is it possible that mine doesn't have a vacuum switch?
Expert:  Tim's Auto Repair replied 6 years ago.

yours should have the switch..this is what operates the actuator under the battery

thanks
