At the top of to door openeing, on the wall is a horizontal bar with
two coil springs. At the end of the bar are two pulleys with cable
that go to the bottom of the door. I think this is a counter-weighting
mechanism to enable easy lifting of the door. The right-hand spring
seems broken. The cable on the right is slack, the cable on the left
is very tight.

When the torsion spring broke, it apparently jammed somewhere. *You'll

I doubt that's the reason, the door should be able to be move up with
one or both cables slacked.
The OP didn't describe the size or material of the door, but it's likely
just too heavy for him to lift by himself. He should get a few strong
friends and give it a try.
My single width garage door exerted a downforce of about 250 pounds when
almost closed and resting a scale with both cables disconnected. I
probably could have lifted it by myself but didn't want to risk a
hernia. (I made that weight measurement to determine what strength
expansion springs to buy when one of them bust. No color coding on the
original springs.)

I always forget to mention something crucial to my problem, don't
I?
It is a double-sided garage door made of wood with foru windows along
the top. The door is quite old, if it is as old as the house, it is
upwards of 25 years old. We were actually thinking of replacing it,
since it is starting to rot through at the bottom.
I checked and the rollers seem free in their tracks and the cables
don't seem jammed anywhere.
If the door weighs 250 lbs, then that would explain why I can't open
it. My one neighbor recently moved out and the other one is disabled,
so I can't count on them. I've found a guy on CraisgsList that said
the'd come out for $99. Hope he's good.
