04 navigator is blowing ac fuse 11, ac coil shorted, 3 different coils, can ac compress short the coils
Tested from fuse 11, relays, replaced ac relay, ac diode, multi-function relay, test from ac relay to compress, test said replace ac coils, after 3 coils, 1 was ford, 2 were auto parts store. I've pretty much tested every thing, I even run a wire with inline fuse to compressor and ground to compress, can a ac compressor ruin the coils or is the ford ac coil built different than other brand of coils. I think the compressor or the ac coil is the problem. the coil still worked but blew the inline fuse in about three min.

How did you hook up the inline fuse to compressor and ground to compress ? Ground what ? Right at the clutch coil ? You have to be hooking it up wrong . The compressor can't cause the clutch coil to short or blow the fuse , even if the compressor were seized up . An before that would have the serpentine belt would burn up , squealing noise. applying B+ voltage in the relay socket ,pin 30 to pin 87 will engage the compressor clutch . If the fuse blows the wiring from the relay to the compressor clutch is shorted to ground . Look for rubbed through wiring harness .
