Many of todays newer cars are equipped with a cabin air filter that the vehicle owner is not even aware of, if this filter clogs up it will reduce air flow into the passenger area and result in reduce heating and air conditioning efficiency, a common question is, how often should cabin filters be replaced? Car manufacturer recommendations vary, but in general the cabin filter should be replaced at least once a year or every 12,000 to 15,000 miles. If you drive in very dusty areas or if you experience an unpleasant odor you may need to replace the cabin filter sooner. If the filter is not changed it becomes saturated with air-borne contaminates. This can lead to poor air conditioning performance and restrict airflow through your ventilation system.

What's that smell? This has become an increasingly common complaint. It seems that this type of complaint is coming from owners of late model cars and almost always cars with R-134 systems.
This is not a new problem; it's been around ever since there have been air conditioners in cars. But if this is an age-old problem, why is it becoming more common? Before we can figure out how to get rid of that smell, we have to understand what's causing it. The origin of the smell is caused by fungus, bacteria and other microbes growing in and around the evaporator of the air conditioning system.

There are a couple of simple things that will help reduce the problem. One is to keep a spray can of Lysol in the car and spray it into the air intake one a week. That will keep the problem under control. Another is to shut the air conditioning off about a mile or so before you get to where you're going and allow the evaporator to dry out. While this is not the easiest way to combat the problem, it is the least expensive.. The moisture-laden environment in and around the evaporator is very conducive to the growth of these organisms

Water on passenger floor of any vehicle usually indicates a clogged drain tube from the heater core/evaporator housing. This tube normally extends through the fire wall into the engine compartment. If the drain tube becomes clogged, the water removed from the air passing through the evaporator will back up and run into the passenger compartment. This is usually a quick and easy fix with a short piece of wire that can be used to clean out the drain tube. If the water has a slippery feeling and is greenish in colour you have a different problem, and the heater core is more than likely leaking.
