Why Has My Car Air Con System Stopped Working?

In order for an air conditioning system to work efficiently, it must produce the correct pressures on both the high side and the low side.

Any obstruction inside the air conditioning system can create excessive pressures on the high side and extremely low pressures on the low side.

When the pressures are not within specification, the air conditioning system will not cool efficiently, if at all.

Blockages can be detected by connected gauges to both the high and the low sides of the air conditioning system. Normally blockages are found in the condenser and the expansion device.

We recommend having your car air con serviced at least once a year. Here are some questions that you might want to ask your auto electrical provider:

• What happens if I continue to use my car’s A/C system, even though it’s not cooling properly?
• Water drips underneath my car when I use the A/C system. Is this normal?
• A musty odor comes out of the A/C vents at times. Can anything be done about this?
• My car’s A/C system seems to cool intermittently and I hear a clicking on and off from underneath the hood. What does this mean?

Excessively high or low pressures in AC system tubing will cause the system to malfunction

Automotive Electrical Designs have the right tools and technical expertise to test your car air con for any blockages and quickly repair any faults to ensure proper functionality and long-term efficiency of your vehicle air conditioning system.
