He find it strange initially, but he manage to find out that it is pressure related. I immediately recognize that Prelude air-cond will not turn on under 2 conditions:
- Refrigerant pressure too low
- Refrigerant pressure too high
On this Saturday, Eddy released some refrigerant to reduce the pressure, and the air-cond works again.
This does not last until next day Sunday. At afternoon, I drove the car to farmers market for grocery. The air-cond stop working after 15 min. I released some refrigerant again. As expected, the air cond able to start after that. I'm glad that I gain this knowledge, as this is not mention in Honda Prelude technical repair manual at all. The manual only said if pressure too high, it will damage the condenser. Eddy believe it is the thermostat switch failure
