Exclamation AC Compressor fuse/relay location?

Hello im new here and only created this account just so I can fix what I think is a minor issue that I seem I cannot fix. Its a 2011 4matic ml350 w164 and recently the AC was not blowing cold. Found out that the clutch for the AC compressor broke off and I recently just replaced it. I had my friends at jiffy lube recharge it with refrigerant and waited the next day to see if any refrigerant leaked. No refrigerant leaked but for some reason my AC still won't blow cold. (my brother owns the jiffy lube so I know there isn't any shady business) I then thought maybe a fuse or a relay could have blown when the clutch broke off the ac compressor. I checked the manual and found the location of the fuse #124 in the engine compartment which states a 7.5 AMP for power steering/ AC compressor. I then saw that this location does not have a fuse and its only a insert for one prong fuse? I circled it in red inside the picture, hope someone can help direct me to the right location?

Please update your profile to include the year, and the model 350 Gas or 4matic and where you live.

After doing that post your full vin#. There are different diagrams for A/C codes 580 & 581.

You’ve circled a location for addition of an option. There will be a usual dual prong fuse and a wiring harness associated with that option. It seems highly unlikely that the fuse holder and wiring would have been removed, so I’d conclude your vehicle never had the option at this location. There is of course no such thing as a single contact fuse.

Guys,
Did all W164s have clutchless (variable displacement) compressors?
