Hiya friends.
Probably should read Vacuum solenoid/actuator line tracing.

Tracing vacuum lines from my dash control **** to the different solenoids or actuators under the dash.
Help identifying which line goes to what and for what. Make sense?

Red vac line goes to upper actuator in drivers side footwell. What does this one control?
Yellow and blue go to the lower actuator in drivers footwell. What does this one control?

Have no idea on the white and black. If they go to one or two actuators? Annnd what do those two control?

Hope this makes sense?
Could use a little schooling. Trying to learn the system a little bit.
Went to the junkyard today to tear into a couple of trucks.....it's how I learn what is what before testing into my rig and usually half the work I'd done for me at the J/y.

Thank you for the guidance as I track down a vacuum leak.

These lines are for the heater/vents/A/C and switch between floor/dash/defrost vents and fresh or recirculating air. Line colors/functions are the same for manual & digital controls

 

Yep, understand that Travis but which line controls which is the question.

 

Deflects air flow between panel and defrost.
Deflects air flow between floor and panel.
White controls outside air vs. recirculate.
Black is the vacuum source.
