Hi all, first post here, looking for some help!

The cable to my temperature control broke and while pulling the control panel off of the left side of the dash, most of the vacuum lines that attatch to the control panel came off.  I cannot figure out how they go back on.  All I can get out of my environmental system is heater air, I can't get the air to come out of the vents if it is set to just vent air, and I can't get the defroster air to come on when set to defrost.  The only place air will come out is through the heater outlets at the bottom, no matter what position the switch is set to.  I've tried trial and error for hours, with the engine running and without, and I can't figure it out.  There is no good diagram in the service manual.  Winter is fast approaching, so if anyone has some advice, I would really appreciate it!

Thanks!
