How to change a Mercedes w202 cabin air filter..What should be a 2 minute routine maintenance item can become a mess...your Mercedes cabin air filter should be changed regularly to extend the life of your fan blower motor,and maintain proper airflow into the cabin..after around 80-90k km this cabin air filter is seriously blocked up and causing strain on the fan blower motor..Mercedes w202 c230 shown,but other Mercedes are similar and equally important to change/check regularly follow me on twitter / fupabox
