This under-dash A/C system mounts securely to the bottom edge of the dash and is a simple installation. For an original, familiar appearance, this system has chrome ball louvers and a brushed aluminum face. The four-speed switch works the 3-speed blower motor with dual fan wheels, which will give about 260 CFM of airflow. The condenser assembly offers the best cooling capacity by utilizing an aluminum condenser assembly with a factory-style drier and mounting brackets. This A/C system is for use with 134-A refrigerant, which is not included. Only works with alternator equipped cars.
