Air Condition Problems

Hello all, long time viewer first time poster.

I own a 97 z28 and I'm having some AC problems. When I turn my AC on max it will sometimes take about 5-10 min. before I can here the compressor cycle on. After I here that click it will blow out ice cold air but may only last for about 30 seconds and then it shuts off. It seems to be random between the times it cycles on and off, sometimes it will stay on the whole time i'm driving, I have no idea what the problem could be.

Please help, my warranty is up at the end of the month.

have the high / low side pressure switch checked...

sounds like that is the problem...
