Ok so I think I have traced my problem down to my diode #48 under the hood fuse. So I jump the low pressure switch behind the motor and my ac clutch fuse pops I un hooked the ac compressorand it still pops. Does anyone have a part number for the diode or link I can get 1. Ford told me they have no idea which I dont make since.

There are two different types, the leg configuration,just verify your diode
legs match one of those.

O ok doesn't matter than I was looking for the 1 with 1.0 on it well that works thank you

If you're looking for 1.0 specific: https://www.oreillyauto.com/detail/b...0113xp/4414229

They're basically a 1AMP fuse that only allows current flow in one direction.


The black ones on eBay should be 1AMP, they're black, so the voltage
rating on those is higher, which is what you would need, not a gray one.

Why?
When the compressor clutch is disengaged, the magnetic field in the compressor coil collapses rapidly which induces back
EMF in the coil winding. This reverse current can reach over 250 volts depending on the windings in the coil. To prevent this
reverse over-volt condition from travelling "upstream" and damaging other parts, the clamping diode is arranged to "clamp" the
condition to the compressor coil.

Ok that .makes me wonder what my problem is than. So my ac clutch fuse pops #48 under the hood I have a 15amp fuse in there. So I unplugged the compressor and un plugged the low pressure switch behind the motor. When I jump the low pressure switch the fuse pops. I remove the relay and the fuse pops i cant figure out why.
