AC air not very cold coming out inside car
After it warms up the air coming from ac isn't cold at all. It's like regular air. Is
there some switch that doesn't let hot water from radiator gp through heater
You might be low on refrigerant or it all leaked out. Does the compressor cycle on and off when the AC is on? Open the hood as the car is idling to see.
If the compressor clutch is not turning at all when the vehicle is at idle and AC on max, you could have a leak and the system is low on refrigerant. If the compressor appears to be working properly then your problem could be at the blend door. Try warming up the vehicle to temperature and switching to "heat". If the air coming out is hot, then switch to cold and see if you can hear the blend door move. If the air stays hot, the problem is within the dash.
