Hi all,

I'm hoping someone here has an idea or advice for what could potentially be happening with my 2013 C300.
This is my first time running into an issue like this. My AC went out today, and is now just blowing hot air, plus being much louder than before.
When I got into my car today, the following has happened:

1. Car wouldn’t turn on.. no ignition after turning key, not even cranking. (Cluster lights went all ON though)
2. Waited a minute and tried again.. car turned ON, but started to sound louder than usual.
3. Noticed that AC was just blowing hot air
4. When turning car off, the engine fan keeps running on very high for a couple seconds. (It didn’t do this before)

I checked battery voltage, shows 12.4V
Checked low pressure AC line with AC/Pro gauge.. needle was in the RED (very high pressure)
No fault lights or messages on cluster

I’m assuming the AC compressor might be dead, but honestly I'm not sure. Perhaps someone here has an idea what could be the issue.
Any feedback is appreciated.
Thanks!
