4wheel drive will not engage

There are three main things that could cause this. #1: in the passenger side kick panel is a module that controls the 4x4 and it should be clicking as you try to put it in 4x4.#2:There is a vacume activator switch on the transfer case located on the top on the drivers side.(If the module is clicking and trying to put it in 4x4 then I would just go to this activator switch).#3 If you replace the switch and it still dosn't go in to 4x4 there is a vacum diaphram under the battery tray that pulls the front end into 4x4.Check and make sure that there is vacum getting to the diaphram which is controled by the activator on the transfer case.If no vacume at the activator or diaphram check all the vacume hoses going into and out of the activator.If no vacume while vehicle is running suspect bad vacume line.You will need to remove the battery to test the diaphram under the battery tray.You will need to hook up some kind of battery to the cables with the battery out of the car to get it started in order to check for vacume at the diaphram.
