norris style

hey guys i have a 1998 dodge ram 5.9 360
there is a vacuum leak somewhere i have no clue where it is
my 4x4 is not engaging and my heater and ac go to defrost when i push the gas. please help i need to find this as it is snowing where i like and i have a pregnant wife that i may need to drive in crazy weather to the hospital i need the 4x4

is there a easy way to find it or is there a certain one that controls both of these? is there a map??








thanks mark
