How do i clean the air conditioning in my 2006 vw passat?

To clean the air conditioning in your 2006 VW Passat, start by replacing the cabin air filter, which can often get clogged with dust and debris. Next, use an A/C cleaning spray designed for automotive use; follow the instructions on the product to apply it through the air intake vents. Additionally, running the A/C on the highest setting for a few minutes can help circulate the cleaner and remove any lingering odors. Finally, ensure that the system is free of leaks and that refrigerant levels are adequate for optimal performance.
