I'm on the same boat as you. Just replaced the thermostat in a 90 Lebaron as it was blowing cold air and when i went to replace it the thermostat it was installed upside down with the spring facing up. Thinking this was the problem, I installed the new thermostat with the spring facing down with a new gasket. Took it for a test drive and the car's heat gauge goes full. Anyone know anything about this problem? It's in the 3.0 Lebaron.
