correct.

 

okay so i check the vac line one was kinked so i changed it now im pretty sure 4wd works bc i took it into a empty lot and cut the wheel and the tires skipped (did not to this for long bc i did not want to break anything). But the light still doesn't come one. Is there a switch i can replace?

 

Switch is on the inboard side of the CAD housing. There is a two-wire electrical connector on it. It just unscrews from the housing.

You can test the switch by removing it, plugging it back in to the electrical connector, and then pushing in the plunger, and see if the light in the dash comes on. If it does, the switch is good, and the actuator probably isn't moving far enough to engage it.
