AC is working when it feels like it wants to. My first thought was the relay. Swaped it with the wiper relay and still not working.

My next thought is the pressure switches. Is there a way to jumber either the hi or low pressure switch to determine which might be the issue?

Since it works sometimes I do not think that it is a freon issue, although I will be check that soon with gauges.

Anyone have any other thoughts of what I should try or anything else to troubleshoot?

Thanks
