2019 GLC 350e AC not cold. Codes: P06A0, B2294, P2610
I have a 2019 GLC 350e with over 76k miles on it. Started up the car yesterday morning, heard a subtle clunking noice from the engine compartment that lasted a few seconds. It sounded like a clutch or something trying to engage but then stopped. Next thing I notice is that the air from the AC is blowing warm air. I continued my half hour commute to work on the highway all while turning the AC system on and off periodically to see if the cold air would start. No change. Drove home after work in the same condition. This morning I start up the car to go to work again and this time the check engine light comes on the dash. Did not have this light yesterday. Stopped by Autozone to use their OBD reader and these are the 3 codes I got:
P2610 - ECM/PCM Engine Off Timer Performance.
P06A0 - The actuation of the refrigerant compressor has an electrical fault.
B2294 - The electric motor of the electric refrigerant compressor is blocked.
Started up the engine tonight with the hood open to figure out what it could be. I even attempted to add R134a to the low side port but there was so much back pressure when I tried to attach the refrigerant nozzle to the port I had to assume there wasn't an issue with low freon.
I read something on another forum that implied it may actually be the 12V battery dying that may be wreaking havoc on the electricals. Can anyone help shed some light on my situation? Thanks in advance.

DEFINITELY check your battery! These cars will have lots of malfunctions and trigger codes with low battery voltage. Don’t just check it with a multimeter. Either load test the battery, or check it with a conductance battery tester like MB does.
Good Luck!
