I start the car and it takes forever for the cold air to come out of vents. Once it does it stays pike this all day, super cold. Fan on as it should blower works like it should. Strange

Hello, have you checked the refrigerant pressures? If you do not have a manifold gauge set, I would not bother using the simple low-side gauges you get from the store. A manifold set can be relatively inexpensive but maybe not worth the investment depending on your use. Sometimes an evacuation & recharge A/C service will improve the performance, which is essentially an oil change for the system. It sounds like to me the compressor may be having a hard time getting the lubrication it needs.

It sounds like a possible Blend Door or compressor engagement issue.

Your climate control system uses electric actuators to move “blend doors” that direct airflow through the evaporator (cold side) or heater core (hot side). If one is sticking or moving slowly, it may take a while before air is directed through the evaporator, which causes the cold-air delay.

Sometimes the compressor clutch or control valve engages late. If the clutch isn’t engaging immediately, the system won’t circulate refrigerant to cool the evaporator until it finally kicks in. This could be a weak clutch coil, failing refrigerant control valve, or electronic delay from the ECM. If refrigerant is slightly low, the system may take longer to build enough pressure difference for the evaporator to produce cold air. Once running, it stabilizes and works fine.

Here are a few quick checks you can do:

When you start the car and turn A/C on, listen under the hood. Does the compressor clutch click on right away, or does it wait a while? Check if the airflow is immediately strong but warm, or if it feels like it ramps up colder gradually.

Scan the car with a good OBD2 scanner that reads climate module codes, sometimes there are hidden codes even if no warning light is on.

The two most common fail points in this scenario would be the refrigerant control valve in the compressor sticking, or blend door actuator lagging.

Hope this helps.

From what you described it could be low on Freon or over charged, both can cause it to not cool quickly. An A/C pressure check can help determine if it has this issue. We need to check the high and low side pressures when it first starts and then again when after it's cold.

If you can get a manifold gauge set to look at both high and low side pressures, this will help me better determine where to proceed.
