The Kia Optima, which is also known as the Kia K5, is a popular line of cars that are moderately sized. They are marketed internationally through multiple nameplates, but some drivers have encountered the following Kia Optima Fe A/C problems.
The Vents Aren’t Producing Air
If you notice that the Optima’s air conditioning isn’t pushing any air out of the vents, there are multiple issues that can cause it, which include:
- Damaged blower motor: This component is responsible for pushing air through vents, but if it malfunctions because of age or wear no air will come out.
- Blown fuse: A blown fuse means that no power can be provided to a blower motor which will stop air from traveling through vents.
- Bad relay: The relay is responsible for extracting miniature electric current then using it for regulating ventilation current, but won’t be able to do this if it’s faulty.
Air Conditioning Produces A Mildew Scent
If you detect the noxious scent of mildew after turning on your Kia Optima’s A/C, this means that bacterium has accumulated within the unit. This often occurs in vehicles that don’t use their A/C that much or which use it on the highest settings excessively which produce extra moisture which attracts mold, fungi, bacteria and various microorganisms. The solution to this problem is to replace the air filter and apply an anti-mildew solution to remove the unpleasant scent.
A/C is Initially Cold Then Becomes Hot
If your Kia’s air conditioning works normally at first but becomes extremely hot after operating the vehicle for a certain period of time, this means that you might have an expansion valve that has failed or is blocked. This stops refrigerant from getting to your evaporator and any moisture present will cause valve freezing. The solution to this problem is to have a technician test the system then remove the obstruction or replace the evaporator if it’s faulty.
A/C Makes Unusual Noises during Operation
Air conditioning noises are never a good sign, whether they come in the form of rattling, clicking, or banging. While it might be caused by leaves or road debris which is causing the blockage, it might also signal the malfunction of an essential component. For example, a worn bearing will generate a squealing or grinding sound, while rattling might signal the failure or a compressor clutch. Do not continue using the A/C after hearing these sounds as this will worsen the situation, and take it to a mechanic for inspection.
There is Water All Over The Floor
Water that appears on the floor of your vehicle seemingly out of nowhere is an indication of bacterial growth within the evaporator coil which can be found beneath the dashboard inside the heater box. This bacteria then combines with coil condensation, producing slime along with the air conditioning fins which culminates in a moldy scent, and this slime might also clog up your drain line and if the drain line uses rubber hosing which starts at the evaporator box and then extends along the floor, water resulting from condensation will fill up inside your heat box then start dripping onto the floor, usually on the side of the passenger. Drivers that notice this should immediately take their vehicle to get it serviced.
