got a message stating "A/C off due to high engine temperature".

Hello, engine temperature being too high is typically caused by sticking thermostat or perhaps engine cooling fans that are not doing the job needed to cool down an engine when the vehicle is not moving quickly creating more airflow naturally. Check for fan operation and lack of debris restricting air flow around the radiator. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
