Default Blowing Hot Air

sup. Oh how I love my villa I try to do everything to keep it perfect and I got a new problem I cant seem to figure out im guessing its a couple of things and I have to elminate them one by one.

Its a beautiful sunday about 60 degrees nice and sunny and im riding clean, feeling good, hit the fan button on the ECC turn it to about 62 and keep riding until I notice the air blowing out feels like 80 degrees. I try to turn the fan to coolest temp and still blows hot a** air its like driving in a sweat box. I turn the A/C on but that aint no better it works takes like 10 min to work but it blows comfortable air not freezing cold air like it should. I cant figure out what it could be got alot of ideas.

Water pump, radiator, airmix actuator, "Just get my A/C serviced", low coolant (change)?

Well since you did not turn on the AC it might be the actuator you mentioned.

What is the temp on the gauge usually??

From your original description I'd have to say the little door that allows hot air from the heater core into the system is stuck. I know WillWren has described how to fix this numerous times in the past. Hopefully he'll chime in to get you some details.
