my 1992 rangers ac has always worked for me with no problems. I dont drive it hardly at all but the other day i got in it and turned the ac on and i could hear a slight clicking noise every 5-10 seconds, but the compressor clutch will never turn on. It has freon and the red light lights up when i press in the **** on the ac panel. What could be the problem here?
