re: Question for OT mechanics

Quick short term fix, take a small allen wrench and a rag. Uncap the high side ac valve(bigger of the two ports) and stick the allen wrench on top of the pin then put the rag over the wrench. Depress the pin two or three times. This bleeds it. My SIL has a '10. The coil is freezing up causing the pressure to rise and as a byproduct puts a strain on the belt. If that fixes your issue then do this for the long term fix:
The problem I found with a 2008 model is the a/c works fine until it has ran for a while in hot weather. Found the thermistor temp sensor bad. It was allowing the evap core to freeze up and stop working until it thawed out. Easy fix, drop the glove box down and look up to the left top of the box. It pops straight out with a screw driver. Ford motor craft part # yh-1504. Ford # xw4z-19c734-ba. It's a 10 minute fix that will save you a lot of time and money.

Usually when overcharged you will hear the A/C compressor clutch turning on/off rapidly. It overpressures,turns off and does over and over.

You do realize this exists... Right?

Does sense of humor fluid exist?

Does any steering system have an actually secondary coolant filled system? There are PS systems with aux radiators for cooling the hydraulic fluid but never seen one with actual coolant.
To the OP if it is a 2012 it has electric PS and unless their is some weird electrical gremlin that I can't quit work out in my head the two are not connected. Not sure I trust your mechanic at this point. Without knowing the high side pressure/low side pressure and the temp it is hard to diagnose the issue.
The fact the issue started well after the last AC service leads away from too much refrigerant, those symptoms would be immediate UNLESS it wasn't hot enough (ambient temp) to notice. If there is just an unusually high pressure on the high side it could be issues with your cooling fan(s). That normally shows a distinct difference in parked AC temp vs AC temp when moving.
My suggestion is to find a different mech.

I would begin by checking the belt. If it is aged and slipping then the a/c and power steering would both be effected.
