Iso Vac Diagram

[mdwatson]

Trying to find a diagram for the complete vac lines for a stock 86 2.5L with no a/c. I'm having problems figuring out the lines that go in/out the fire wall. Vents are stuck on defrost only and I have no vacuum going to the ball canister at front bumper. Pretty sure my problem is the vac line going into firewall isn't hooked up correctly.

You may have a broken or disconnected vac line behind the dash. With the engine running, stick your head into the passenger footwell, move the selector on the heater controls and listen for a hiss. If you hear anything You can use a piece of vacuum hose as a stethoscope to locate it.

If no vacuum gets to the ball, none gets to the heater controls either!

Think I might have it hooked up correctly now. Have vacuum to the ball now but the vents still aren't working. I assume I have a problem under the dash too.

heater control possibly unplugged?

Pink/purple pipe to heater control valve. Black one to heater controls.

 

Ball is in the passenger side front bumpeer and has a line running to it from the intake manifold and the other provides vacuum to the black line to the heater control.

 

I just move the ball to the engine compartment.
