Clean all the windows from the inside and outside. A window-cleaning spray and glass-cleaning towel will do the job.

The inside of the windshield need a special effort, as any residue will obstruct your visibility.


How to get rid of musty smell from the air conditioner

1. During next oil change, ask your mechanic to check if the A/C drain tube is not clogged up. A mechanic can blow it with compressed air. An A/C drain tube is usually located on the passenger side of the firewall. You can find it following water drips under the car when the A/C is running.

Leaves on the cowl panel

2. Clean the debris from the cowl panel (under the wipers), as the air intake into the cabin flows through this area. Often a damp smell comes from wet leaves and other debris collected there.

3. Replace a cabin filter with a charcoal cabin filter. A cabin filter in your car is similar to a furnace filter in your house. It filters the air for the vehicle heating and air conditioning system. As any other filter, a cabin filter clogs up over time, as you can see in this photo.
Signs of a dirty cabin air filter include reduced air flow and bad smell from the vents. Dust, pollen and other contaminants trapped in the cabin filter can also cause problems if you or your passengers have allergies.
If your car is parked under trees or if you often drive on unpaved roads, your cabin filter clogs up much faster.

4. Before parking the car, turn the HVAC mode to "fresh" air. This will allow some fresh air inside the cabin.

A/C treatment spray

5. Once a year or two do the HVAC deodorizing service. Your mechanic can spray a special spray on the HVAC evaporator to kill off the bacteria and fungi living on the evaporator. Here we used the Air Conditioner Treatment from Wynn's that you simply spray into outside air intake vent (check the directions on the product).

Replacing the cabin filter

Changing cabin air filter step one

In most cars, the cabin filter is installed behind the glove box. For this car, Toyota provided the instructions in the owner's manual.

The first step as per the owner's manual is to turn the engine OFF; of course, we don't need it running. The next step, open the glove box, locate the damper and slide it off. Now, the manual says push in each side of the glove box to disconnect the claws. To pass these claws over the edges, you need to squeeze the glove box gently from each side.
