define constantly kicking on and off. Because it is normal for it to turn on and off at a regular interval. Heat is applied after the air is cooled so the fact that you have the heat on is irrelevant.

A/C cycling frequency is regulated by the low pressure cycling switch. Generally speaking, R134A systems like yours do tend to cycle more frequently than the old R12 systems. If the cycling is a lot more frequent than you remember on this vehicle, have the charge rechecked. It may be underfilled.



AC compressor operation allowed:
Max AC
AC
Vent/Floor
Floor/Defrost
Defrost

AC compressor operation not allowed:
Vent only
Floor only
Off

As shown above, A/C compressor logic is dictated by the mode switch position, not by the temperature selected on the dial. Beyond that, compressor clutch engagement can be disallowed by the Low Pressure Cycling switch, High Pressure Safety Switch or the PCM when in power mode.
