Anthony,

Before you go out and buy a new Mode Door I would verify it is in fact the
door itself that is "binding" for one reason or another.

I have a 1987 New Yorker which has a similar system. I am not sure, but it
may in fact be identical to the 90-93 Imperials. Even if it isn't, it's the
same theoretical design. Electronically controlled temp and mode doors
driven by actuator motors prompted by the digital in-dash "head" unit.

In my case, the problem turned out to be the actuator motor and not the
door. In the New Yorker at least, the motor itself is far easier to replace
than the door itself. YMMV with the Imperial. However, even getting to the
motor itself is a whole LOT of NO FUN.  I can't imagine had I needed to
replace the door itself. Alan is making no exaggerations here.

Your first step should be to run the self-test Alan referred to. Post back
if you get any error codes. I can decipher most of the error codes for you.
Good luck
