Can't figure out what to replace to make air work. Also my snowflake and re-circulation button blinks three times and turns itself off.

Hello, I'm Danny.

Just question first. Do you notice when the engine is running if the A/C compressor on the engine is engaging/cycling? Hope to hear back from you soon and thanks for using 2CarPros.

Well my nephew is saying it isn't he's saying the belt isn't turning the pulley that's he's calling the compressor, but the system is blowing hard air from the vents. But I don't hear my truck kick in and idle in any different way like he says it should. It actually sounds as if the air is blowing extremely hard and fast than it should. I could be wrong.

His suggestion is the belt is not turning to the compressor.

Hello again.

Can you have your nephew pop the hood and with the engine running, A/C set to max settings. Verify if the A/C compressor clutch on the engine is cycling?
