Once the right side vents start blowing warmer, you know you are low on refrigerant and may have a leak. If you put some dye in the system and no leaks are visible on any lines, the evaporator is mot likely the problem. My evap failed twice, so I know
AUC WOULD NOT DO ANYTHING FOR AC. Solar sensor could cause ac issues.

Final stage again as long as the blower is working has nothing to do with it.

Sounds more like an incompetent mechanic than fraud

1. Do not argue with an idiot. He will drag you down to his level and beat you with experience.
2. Light travels faster than sound. This is why some people appear bright until you hear them speak.
