During warmer weather you may begin to notice a trail of liquid on the pavement underneath your recently parked car. On closer inspection, youâ€™ll discover water released as harmless condensation dripping from the air conditionerâ€™s cooling coils. Identifying an actual AC leak can be difficult as the refrigerant found in your car is released only as a colorless and odorless gas. Hereâ€™s how to identify air conditioning system problems, including a leaking air conditioner, and the steps required to fix them.
Identify and Fix Problems
When your carâ€™s AC system needs attention and has potentially stopped working, take the following threeÂ steps in order to get to the bottom of things:
1. Check the fuse box. Something as simple as a blown fuse can shut down your AC system. Locate the appropriate fuse associated with the AC system, and if itâ€™s blown you can replace it. As long as cold air is flowing after that, then youâ€™re good to go.
2. Examine the vents and cabin filter. Determine whether the air vents are open and unclogged, as shut or blocked vents will impede air flow. Another possible impediment is the cabin air filter. Locate, clean or replace the filter if itâ€™s clogged.
3. Look under the hood. Examine the AC system for signs of damage. Any part associated with that system can cause it to stop working. These include: a malfunctioning switch, a burnt out relay, a failed compressor, a damaged cooling fan, a clogged tube, frayed wires or problems with the condenser or evaporator. For most people, diagnosis and repairs are best left to the professionals. Take your car to a service technician if you donâ€™t have the tools, talent or time to get the job done.
If youâ€™re not comfortable working with your carâ€™s AC system or if the problem is more complex than outlined here, then take your car to a service technician. Your mechanic will add a special dye to get more information on your leaking air conditioner. When illuminated by an ultraviolet light, AC leaks can more easily be found and the proper repairs can be made.
