take a photo, sounds like it could be the vacuum pump.

If it runs constantly, you probably have a leak somewhere.

take a pic tho

It controls anything the normal vacuum pump would- like the vent/defrost position for heat and ac. Also controls the ESOF mechanism for the 4x4s that are equipped as such.

Yeah, its the vacuum pump. I'm not the best at explaining this, but if you'll notice on a gasser motor all the vacuum lines used to run brakes, etc. are run to the intake where they get that vacuum. On a diesel it doesn't work that way which results in needing a supplemental pump to operate various things.
