'04 Corolla, 175K A/C system had never been touched before this problem happened. A/C clutch will not engage when it's hot outside. Early in the morning or late at night (when it's not so hot) the clutch WILL engage and I get cold air for about 5 or 10 minutes, then nothing until the next early morning or late night. Do you think this is a worn clutch stator (electro-magnetic coil)? I had the system evacuated and recharged with the correct amount of fresh 134a and also replaced the VERY expensive A/C clutch relay. Thanks for the help.
