If I recall, in 1994, they used a steel cable to move the vent doors. It could be kinked or the vent door could be jammed. I would start by getting under the dash and following the cable to the vent door it operates. See if it can be moved manually if you disconnect the cable. If not, that is the problem. If it moves easily, then check the cable itself.
