AC only works sometimes, when it doesnt want to blow towards the passangers it blows on my windshield
Make sure the vents are open. Also make sure you turn on the passenger side a/c button.
sounds like the control in the dash is going out preventing the drivers side from working and the passengers side wont be working for long. take it to a shop that knows how to properly diagnose electrical issues.
Sometimes i hit a bump and it starts blowing towards the driver and passenger but when it is not working properly it blows towards the windshield.
