On my 2000 Ford Expedition the A/C clutch will not cycle on and off. With the outside temperature @ 75 deg. the low side shows 40 psi. and the high side reads around 160 psi. From those reading I think the charge is ok in the system. So with the control inside the truck on a/c only shouldn't the compressor clutch cycle on and off? I know if the controls inside is set to Max then the a/c clutch should stay engaged all the time. Is there a switch in the system to tell it to cycle on and off. If so where is it located and how do I replace it............Thanks in advance for the help...........Gary
