Are you sure there is not a damper installed in the duct?
My system has dampers on all ducts located near the furnace at the main
plenum. Look for a small handle sticking out he side of the duct(s).

I'd try the local tool rental shops for a camera. Or take a look
online. There are cheap cameras you can hook to a notebook PC. You
might be able to use one of those connected to a snake with a
penlight, etc.

If it's a small duct, It's also possible that with multiple 90 turns
and a long run, the duct isn't blocked, it just can't carry much air.
