My AC blows warm air. Help PLEASE
My wife's car is a 2007 E350 Sedan. Since we live in San Diego, we rarely use the AC, until last couple days the weather turns hot. I turn on the AC and find out it blows only warm air. What could be wrong. Do you think I need to put more Freon to the car. Or maybe an AC switch is bad, or relay is bad?
Help Please.

Cars went long way in last 25 years when set of gauges could do most of AC troubleshooting.
Those cars have 8 or more sensors that are giving data to computer to run the cooling program. If you have a gauge already, you can try your luck with checking the REFRIGERANT pressure , but for the rest you need readable climatronic or SD.
Do you have REST button?
You must live close to the Ocean? I spend some time in Escondido and it was darn hot. Had to use AC even in January.
