Q. Last fall my air conditioner did not seem to be very effective, I thought I would wait until spring to have it replaced. What usually causes the air conditioner to blow just cool air?
A. Many things can cause an air conditioner to just blow cool, not cold, air. Typically it is a sign that the system is low on refrigerant. However other causes could be a blockage in the system filter (orifice tube), a faulty pressure switch, a cooling fan problem. Some vehicles are equipped with a separate fan just for the air conditioner. It could be something as simple as debris in front of or between the radiator and condenser. Your regular technician should be able to inspect your air conditioner system and solve your problem.
Q. When I use my air conditioner I get a very strong musty odor. Is there anything that can be done to eliminate this smell?
A. This is a common problem that customers complain about in many different types of vehicles. The first component to check is the air conditioner drain. This eliminates condensation that forms when the air conditioner is used. If the drain is clear, there is a procedure that can be performed to disinfect the air conditioner's evaporator and help eliminate this odor.
