I was reading the topic "94 Explorer A/C Clutch not operating" posted in
late May; I have a similar problem on a '94 and concluded that the system
was likely low on refrigerant based on voltage readings at the pressure
switch.
The problem I have is compounded. When operating in defrost mode last fall
the AC clutch or compressor seized causing the belt to burn up on the
pulley, I immediately disconnected the connector to disengage the clutch
before the belt was completely ruined.

My question is: Could the system being low on refrigerant cause the
compressor to lock up or do I also have a bad clutch or compressor in
addition to low refrigerant. I'd like to have some idea of the problem
before going in for repair since this is likely to be an expensive
repair.
Thanks in advance for any help.

If your compressor locked, it's toast. Best go have it fixed, and
convert the system to R134A

I thought the 94s already had R134a. Mine did.

My bad. I have a 92, and mine didn't. I suppose it begs the question
what year they changed to R134A.

1994 was the year (IIRC) that the vast majority of mfgrs went to
R134a; after the end of December 1995, R12 was illegal to manufacture
in the US (and most other places).
