A/C problem gets warm air after long high-speed drives?

So, the AC temp issue and the vent issue are separate problem, please start a new thread for the vent issue, we will handle the AC issue on this thread. Can I ask if you hear the radiator fan clutch kick in while driving (hot), if not this will be the issue with the AC, the pressures look okay on your gauges. Also, I would use a garden hose and blow out the cooling fins on the condenser and radiator. This video can help as well

Let me know :)

Hello, I have checked out the fan and it does appear to be working. No signs of overheating or any weird noise are coming from the fan. The fan can also spin when the engine is off with some resistance.

You may have an evaporator that is icing up, after the AC stops working and you park the car, does it leave a large water puddle under the car? Please go over this guide.
