My AC on my '00 SE was working intermittantly. The Thermal Control Amplifier (TCA) is buried in the dash requiring dash removal to replace. My wrench just hotwired across the TCA (which apparently keeps the evaporator coils from freezing up) and told me to shut down AC breifly if air stops coming out of the registers(freeze up) - with no harm to system. Have had no problems since ... Good luck!
