Vacuum would have been my first guess on the idle issue...
If the ac being on produces so much of a load to almost kill the motor... have you checked your batt/alt?
Also, with the fuse blowing I would check that circuit. Is the fuse for the compressor or the blower?
If it's the blower, then your blower could be bad. Might also have a short somewhere in the wiring.
There's a reason you're blowing that fuse. Only advice I can give you is try different things related
to your problem until you find it. I wish I could give some better advice, but this is all I can think of.
Would've responded sooner, but I was hoping someone a little more knowledgeable would respond first.
GL man...
