I recently bought this car and knew about the problem but figured no big deal about it until recently. The A/C works but only on settings 0,1, and 2. Once turned to 3 and 4 the A/C shuts off. I believe it does the same with the heater. The cooling problem would be that the temp guage is showing the car to be overheating when it is at a stand still. I had the coolant flushed and replaced by the mechanic, as well as the thermostat and the housing for the thermostat. It cools fine when driving but when idle i must put the car in neutral and rev the engine as the temp goes back to normal slowly but surely. If anyone can help with either of the 2 problems I'd appreciate it.
