RE: A/C not working
Do you have a set (high and low pressure)of gauges to aid in the diagnosis?
How did you determine it has a full charge?
Have you checked for codes?
What is the temp coming from the vents?
A/C systems have so many elements just posting a one line question makes it near impossible for anyone to help.

It is a normal part of how this system works.
The frequency may indicate a problem but if the compressor runs constantly that would indicate a problem also.

On some issues, specially with A/C & airbags, we are very reluctant to provide suggestions unless
