The wiring to the AC clutch is good. There is no fuse in #7 spot, but # 9 for "relays" is a ten amp and good. The problem lies, as I stated at the outset, that there is no ground to the COIL side of the AC relay. (Slot # 39 in the fuse block for the AC relay is hot. Slot 31 becomes hot when the relay plulls in, and energizes the clutch. Slot # 19 is hot when the key is on, and slot 21 is the ground side of the relay coil and apparently is controlled by the blower switch inside and? Else.) When I add a ground to the coil side of the relay, (slot # 21), the clutch pulls in and the AC cools, but the coolling fan does not come on, and head pressue goes too high, (Over 300#) so the ground side of the relay apparently controls, not only the relay, but also the operation of the cooling fan, (There is only one--both for the radiator, and the
ac condenser.), When the engine temp is low. Thanks Again for all your trouble.
