My a/c compressor keeps cycling on and off but has a full charge.I was told that the fan motor in front of the radiator is not working,so this causes the compressor clutch to work much more coming on and going off rapidly?Is this my problem or what? Any help with this matter would be greatly appreciatted.

Who the hell knows for sure? Your going to have go thru the diagnostic checks to find out for sure. Pull the bumper or grill, whatever you have to to get to the fan, and check it to see if it's getting power, and signal, when it's supposed to. It sounds like you may need to take it to a qualified repair shop. If you can do electrical diagnostics, you can probably figure it out for yourself. If not, pay a pro.
