can anyone tell me what the normal AC high and low side pressure readings should be when checking with a set of guages? My A/C cycles on and off and the last time I checked the low side only with a freon fill kit it showed there was enough freon in the system. still does not blow cold and as I said the compressor cycles frequently.

 

There really is no way to tell you that, all depends on ambiant temp.

The system is designed to hold a certain weight of coolant, so your system needs to be evacuated and then refilled with proper weight of coolant. Add too much and you will be popping hoses or worse. Can be dangerous too, there is no high side fitting either.
