I had the trifecta issue almost for 2 months and in the end it was a bad alternator. Stereo and a/c would cut off for about 30 seconds and after clearing the error codes, a short drive later the 3 lights were back on again.
Make sure you're getting a good charge from your battery and alternator.

Good luck!
