I have a 2002 Rodeo with 3.2 V-6, 4x4 and while driving the 4x4 randomly tries to engage without pressing the 4x4 dash button. After reading several threads I decided to check the vacuum lines at the axle and I discovered that I have only 1 vacuum line on the motor, not 2 like the worthless Haynes manual shows. I finally removed the motor after locating the wiring connector, which again was nowhere close to what the pictures in the manual shows, and removed the plastic cover. This motor does not have any vacuum switches inside, it's all electric.
What is going on its this thing? Why only 1 vacuum line? How do I test the motor now to see if it's working? The wiring is 4 wires, blue, green,white and black. I'm guessing the 4x4 dash switch just changes the polarity to reverse the motor, but because my 4 wire colors don't match the wiring diagram I am not sure which wires to power for testing.
What is also strange about this is that the transfer case motor should not be working at all, one of the magnets inside the motor came unglued from the housing and it is not engaged.
Is the 2003 model year different and I possibly have an early 2003 model even though the VIN indicates 2002 model year?
