A/C clutch won’t engage.
System charged, replaced 10A fuse and relay. Still nothing.
Jumped relay pins in fuse box at 30 and 87a, clutch doesn’t engage.
Unplugged connector at AC, when those above jumped no power measured in connector plug.

Connected jumper direct to AC from battery, clutch engages.

Soooo….
Jumped the Low pressure switch, no change....left it jumped and jumped the High PS...no change, still no power to the AC plug when 30 and 87a jumped.
Further testing shows that there’s no power going across either jumped switch, as well as the AC connector plug…..
Tried all tests with ignition switch on, and off, and AC dash switch on and off…still nothing.

Saw a vid about an 06' Explorer that had a fuse in the inside fuse panel that was also associated to the AC...he stated that there was no identification in the manual about it?????
