Climate control the a/c temp gets warm after some time, ever the air also doesn't blow at lower temp.

Is the temp gauge running in the middle or is it lower? If the gauge is lower than normal you need to replace the thermostat. Could also be low on coolant so check coolant level. Could have a problem with the climate system but check the first 2 items first.

You should have dual zone climate control,
Check your menu for climate and lower the passenger temp.

Temp gauge should read about 1/2 way if the vehicle engine is at proper operating temp. If it is lower it is why you have luke warm heat. If the temp is ok get the climate control system scanned for faults.

Could be one of several things. Your car has automatic climate control that takes air temp and coolant temp into consideration in controlling the heater components.
The heater blower will not come on until the heater warms up. So the engine thermostat could be faulty and the engine is taking a longer time to warm up.
The electronic controller adjusts blower speed. And the blower motor could be going bad.
You may have to get a shop to take a look at it - someone with the books and tools to test the system.

replace the climate control module
for that sort of money , you will be wasting cash unless you get everything from the junk yard

could be an air lock in the heater rad, back flush with a hose to clear.

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

Start the vehcle and let it warm up then set all the controls to heater? Then turn off the car. Use the remote start to start the vehicle and check the controls are still set to heat mode.

It sounds like the blower resistor is shot. Just change out the resistor and that should take care of it.

Its just a vent damper plate not operating, it's like a gate which controls the flow of air,,usually they are operated by vacuum, or cables.
Service center time, unless you are handy with your own repairs.
