Have you checked the refrigerant charge? You do this with a set of gauges or with a single gauge that your local WalMart or autoparts store should carry. It is check on the LOW PRESSURE ONLY side of the system. That is on the passenger side near the drier (large cylinder close to the firewall). If a system is low on refrigerant, it will cause the compressor to cycle on and off. There is also a switch in the same area, on top of the drier or close to it that senses the amount of refrigerant in the system (pressure switch I think) that could be bad. I would at least purchase a gauge and check to see what it shows is in the system.
Are you saying that an electric fan was installed in place of the belt driven fan?
