AC Blowing only Hot Air
Hey everyone,
My 99 E320 is only blowing hot air during the day when the weather is hotter outside. In the mornings and the evenings when its around 70 or so the AC will be working well. I've recently had my AC system vacuumed and checked for leaks. Everything regarding that came out well. I have ran my diagnostic as well and the only error code I received was related to a defective sun sensor.
Anyone have any idea about what could be wrong here?

Your car is W210, what on US models is equipped with climatronic that will allow you to do full troubleshooting without taking "sausage guy" word for what it is.
Follow the endless instructions and come back with 1 set of sensors readings done on cold morning before engine start and 2nd readings after starting the engine on hot afternoon.
