Question about 1992 Plymouth Acclaim
Check the two tubes entering the firewall that lead to the heater core. If both get hot, then the inside blend door is not actuating correctly. If the heater core tubes are cold, then the heater core is blocked up.
Have the car's cooling system backflushed or replace the heater core in order to fix the problem.
