A/C Clutch, blend actuator fuse #24 keeps blowin

I recently purchased a 2001 Excursion limited 2wd. A/C fuse #24 keeps blowing. it will blow as soon as the key is turned on, no matter what position the HVAC function switch is in (even off).

Disconnected the AC clutch coil (blown fuse), disconnected the blend door actuator (blown fuse), disconnected the plug on the back of the interior HVAC controls where the whi/vio wire runs in (no blown fuse). At this time, I have the plugs all reconnected with the whi/vio wire removed from the plug and taped off until I can figure more out.

Out of frustration, I put a 30 amp fuse in and it didn't blow. After 5 seconds I felt the wire in the engine where the connectors are and it was warm near the high side sensor? (tan/grn wire and red/yellow in it, closest to A/C clutch plug). would a bad sensor really blow the fuse? is it my function switch in the dash?

I'm losing my mind. I also jumped the A/C compressor and it clicked in like it is supposed to without blowing an in-line fuse so I'm pretty sure it isn't the culprit.

I really need some help.

Thanks.

Might have found the culprit

After much searching for four days, I somehow didn't see the fact that the A/C Clutch Diode had slightly melted. I will replace it tomorrow and hopefully that will solve the problem.

The fuse doesn't blow (even with the messed up diode) when I unplug the AC Compressor Clutch and the A/C compressor pressure switch.

I'm hoping that someone can maybe help me figure out what is wrong.
Do diodes get weak and fail over time? Is something else wrong that is causing the diode to fry and in turn the fuse to fail? I really need some help on this one cause I'm baffled.

Thanks in advance.

Problem Solved

New diode installed, air blows cold and fuse doesn't blow.
