Default AC Problem

07Z06

AC cycles off randomly and comes back on randomly.

Doesn't matter if its part throttle or half throttle. There is no continuity or trend to the cycling.

The control panel and all controls work fine, or "appear" to be working fine.

Any insight?

Thanks,
Jeff

More information is necessary. What cycles off, the blower or the compressor. Does the cool air cycle on and off? Low R134 can cause the compressor to cycle. Too much R134 can cause a problem also. Good luck.

The most likely cause is a slow R134 leak. Sometimes you can add a little and it will work OK. It will not work if you have to much R134 also.
