Where are and which fuses are A/C (compressor) related?

The truck A/C air was gradually warming, took it in for a recharge and told it was blowing cold. When I picked it up the air was barely cool and it seemed like the compressor wasn't on. When the A/C is blasting I can feel the truck shaking slightly when stopped at a light. Took it back, put it on th machine, not overfilled, balanced properly and they say the compressor must be rotten on the inside and $1700 for the entire job.

I plugged in the scanner at home and no codes.

Is there a datastream that I should check?

I plan on taking it in to my mechanic next week to diagnose but was hoping to check the basics myself hoping it's something simple.

Thanks in advance for everyone's help.

 

Fuse #12 in Fuse Box F3 .

Fuses #78 & 91 in Fuse Box F33.

 

Thank you.

 

are these AC fuse locations applicable to 2007 ML320 too?
