2002 Jeep Grand Cherokee AC Problem -- Simple Fix!

My 2002 Jeep Grand Cherokee began to blow cold air out the defrost vent *only* -- regardless of where the routing knob was positioned.
A trip to the dealer resulted in the same bad news as reported on another AC/Heat problem thread -- 10 hours removing dash and over 600 dollars.
The Tech there tought of something *before* he disassembled anything.
He found that a vacuum line had come loose from the intake manifold --and this vacuum line controls both the AC air routing system AND cruise control.
My son has a newer Jeep GC --- similar problem (and no working cruise control) --- and guess what?
Reconnecting the line put everything back to normal.
This line is on the driver side at the rear of the engine.
