Car AC problem: The car AC is only cold when driving.

When Its idle, the car temp gauge starts increasing and the AC goes out ( fan still blows, just not cold).
WTF
Start driving, temp goes down and it starts working again.
Should I just not stop at stop signs and red lights?

Sounds like a lack of airflow through your condenser at idle. Check to make sure your cooling fans are running while the ac is on and the compressor is engaged.
Also look behind your grille and make sure the condenser it not covered with bugs and grass.

Condenser fan.
Shop quoted me $800 to fix. I ordered on Amazon with overnight shipping for ~$150 and replaced in 45 minutes.

You probably have 2 electric fans blowing on your radiator. 1 or both is out. Pop your hood and look.

Water pump bad or blockage in lines preventing coolant from circulating in engine?

How can you tell if an electric fan is bad?

Watch it and see if it starts turning. They operate on a thermostat switch. When engine temps rise above a certain point, they kick on. If the engine is hot and they’re not running, then that’s the issue.
When you’re driving you get enough air flow to cool it (for now while it’s not a zillion degrees outside).

I would guess fan and lack of cooling air flow as mentioned above. Could possibly be belt slipping on compressor also. Had this problem after getting a detail done on my truck. They sprayed that greasy shiny shite under the hood and had the belt slipping at idle but once moving the rpm made up for the slip.

New car? Maybe the car's turning off.

You haven't given us enough information to diagnose the vehicle.
I might would start with the belt. It could be slipping, which would cause your water pump and ac compressor to have issues. Otherwise, these issues might be separate problems.
Definitely make sure that your condenser and radiator aren't covered with bullshite.
Losing any water?
Ac compressor cycling?
Low side and high side pressures would be great if you can hook up some gauges.

You probably need new condensor fans
And you probably are driving a Honda.

Maybe bad fan clutch (if you have a fan with one). Sounds similar to what you describe.
