RE: Rear diff lock fixed.

Thanks guys for the quick info.

I was expecting to have to do something complicated like check the variable 
impedance of the super Fromitz valve, located in the most inaccessible spot 
underneath the car possible, while simultaneously checking the line 
pressure of the AC system.

In actuality, it took me longer to jack up the car with a floor jack then 
to unlock the diff lock.  I'll have to go back and check over the vacuum 
system, but It hasn't snowed here in 5 years (And that one time I managed 
to spin my Coupe GT driving too fast, luckily I stopped 1 foot before I hit 
an expensive telephone switching box, got pulled out and went about my way, 
only damage was a bent rear track arm, and I had a local welder reinforce 
it with a steel rod, car always handled better after this), so I should be 
safe for a while.
