Default 05 PTGT A/C 10a fuse blowing, bad high pressure switch or ??

Checked for grounding in both switch connections, both good.

Relay is good.

LP switch is good.

Fan does kit on when AC is switched on, but that blows the fuse.

The pump itself doesn't physically sound very good. Pretty sure the bearings are giving up.

So, can the bearings for the pulley be replaced without replacing the whole pump.
AND, am i correct on assuming the HP switch in the pump is bad and grounding out when switched on??

Want to be sure before dishing out the $$$

What is the number of the fuse that is blown. There is more than one fuse connected to the A/C system.

It's the small 10 amp fuse under the hood near the relays, don't know what number it is. Didn't see any other fuses anywhere else. I checked the box near the steering wheel. Didn't see any for ac there

Likely fuse #11 (10 amp) which protects the A/C compressor clutch (through a relay in the under-hood PDC)
