Martin, The reason they cycle the most is temperature. If you don't move enough warm air over the evaporator core in the car the low pressure switch will protect the system by shutting the compressor off. Here in Texas with 90+ degree weather we or should I say I don't have the problem. Also, Don't run it on maximum, and add a little outside air with the blower motor and run the car on Normal. Normally that will slow it down as long as it isn't low on freon. John Hervey http://www.specialtauto.com/ << My AC is a bit low on R12 and I didn't like how hard it was hammering the fan relay. I remembered seeing this article and realising that my Xantia runs its fans continuously when the AC is on, I wondered why the DeLorean's cycles continuously? Anyone? >>
