line on the right goes to and threw the firewall,one on the left is the broke one


line comes off the intake , tees off the one in the pic is the one I can find, the other one goes to and threw the firewall.after the first tee there is another one that goes to the transfer case with the vent line.i looked for the other half of the broke one but no luck.

Goes through with the a/c lines if I remember.

threw the fire wall? i have one that goes threw by itself with a rubber gromit around it.your saying this broken one goes threw to the cab with the ac lines?

One is source vacuum for the HVAC controls, the other goes to a vacuum reservoir in the valley there with the windshield wiper stuff.

i found it going threw with the ac lines.i fixed the line but it didnot cycle from defrost to vent or floor i pulled the hose off the control that opens the door to vent ,stuck my tounge to it and it sucks a little ,how much suction should it have ?anything else i can check?

Quite a bit, actually. You probably still have a leak somewhere.
