Automotive Air Conditioning Information Forum

Hi,

I’ve noticed that my A/C blows cold air when I first turn it on, but after driving for a while it gradually gets warmer.

The airflow stays the same, just the temperature changes. It’s not completely hot, but definitely not as cold as at the start.

I’m still checking a few things, just sharing the situation here.

James, The first thing I would check is the amount of refrigerant in the system. It could be something else, but let's start there.

What is the make, model, year, and mileage of your vehicle?

Don't forget to check whether heated air from your heater is getting through too.
