Thanks, guys! I was too lazy (Old and Fat, and sweaty, actually) to climb around that hot compartment and trace it out. This forum sure brings out the "Screw it, I'll just post it" in me, at times.
I WAS tracing the vacuum lines to try and find out why my heater wasn't working and the Mrs. asked me what it was. I don't like to lie to (unless I HAVE to.)
Oh, BTW, the heater temp. control cable was stuck and the previous owners forced it and appear to have either broken the plastic housing in the module, or the little blue locking tab that goes into the module to hold the cable sheath.
I'll try and lube the cable up and then try and figure out a way to re-attach it to the module so I can control the cold/hot mixture of the heater. Even though it was 102 today, cold weather is coming and I hate being cold more than being hot. Such is life.
One more thing...
