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.
This is a bad or ...going bad....Mode door actuator. I would recommend you take it to a GM dealer and let them fix it correctly...Cadillacs are not for your average tech to work on...you need someone that has seen and done this before. Remember in this car both the computer and the driver can control the flow of air...the computer determines it if you set the system to "auto" and for that to work...the cabin temp sensors need to be working properly.
