My 2000 Isuzu Trooper AC blows cold for about 15 to 20 minutes and then it will start blowing warm after, need to turn OFF the switch (on dashboard) for about 3 to 5 minutes and then turn it ON before it will start blowing cold air again, this happens during outside temperature is hot. (It seldom happens during morning when the temp is still low) I already replaced the high pressure switch (dryer), thermostat, expansion valve, had the evaporator cleaned/serviced, found no leaks, freon is Ok and also changed the serpentine belt. I replaced the compressor clutch just almost 2 years ago. What might be the problem?
