Most likely the evaporator core in the cab is icing up all that moisture in that Hawaiian atmosphere. Then the thermistor shuts down the compressor until the ice melts and the air can warm up the thermistor.

surfahjammer;

One cause is some A/Cs have a much colder output.

... When first started, an A/C system will dry the air in a sealed area by condensing the moisture on the evaporator core and letting I drip out the drain. But later when the area / evaporator is already cold if a fresh amount of moisture is introduced the A/C will freeze more readily.

... If the fresh air intake is open, or doors or windows get opened more warm moisture is available for freezing.

My old '66 Rambler would blow snow out the vents on a 110 degree day.

EDIT... Slower flowing air may help cause freeze-up.

 Have a good one and see you later… Don S..

It would be nice if our members would add their vehicle information to their signature (similar to mine) plus add their City and State .

A member in the same town might be willing to drop by and help you with a problem. Or drink all your beer! One took my wife!... J/K
