1. Use a vacuum cleaner or compressed air to remove dirt
from inside the A/C unit.
2. Blow compressed air through the evaporator fins from
blower side (A) first. Direct the air straight into the
evaporator to prevent fin damage. A nozzle extension
makes this procedure easier.
3. Repeat Step 2, page 308 at the side (B) opposite the
