Default AC clutch pulling too many amps?

The #8 Fuse-10A Engine Management Fuse Box that supplies 12V to the clutch via the relay. Keeps needing to be replace . This fuse supplies only the Ac Comp. Clutch. When the fuse is good the air is cold and quiet and will run for about 10-20 mins then goes out. I did change out the relay but no luck. It may be the clutch pulling too many amps. I am going to look in to this. The Ac Comp is quiet that why I am thinking clutch. Do you think that code would be on the ac for this? Has this happen to any one else.

Well I had some time today to look at the car. I started off by putting another 10 amp fuse in today. The a.c ran cold you can see that I had my meter on and it was pulling around 3.1 to 3.4 amps. at idle. Next I raised the idle to about 2500 rpm. Then the fuse popped again in my meter, showing a dead short. Then I put another fuses in and it poped right away (like 4 popped one after another) . I took a shot in the dark and pushed on the four level pressure switch. After that it stopped blowing fuses. Now this may or may not be causeing my problems but I'll keep you up dated. I'm posting some pictures for a friend who likes pictures.

thanks

I have read about a few issues with that pressure switch.

From what I understand once the A/C is turned on the 4 way pressure switch sends a signal that tells the compressor it is ok to engages and the cooling fans are turn on. If the compressor is engaging and the fuse blows after when the engine is at a higher RPM I am thinking it might be the radiator fan or the radiator fan control relay module. This might cause the delay in the fuse blowing. Please post what you find.

I hope this helps!
