It Just Stopped Blowing Cold!

There’s nothing worse than getting into a hot car in the middle of the summertime, turn on the a/c and the only thing coming out of the vents is hot air. The A/C is not working. For whatever reason, it also only seems to happen at the most inconvenient times!

There is only one reason why you’re A/C system should work and that is you turning it on. There are multiple components to the refrigerant system and the electronics that control it; at any given time, one or more of the components can fail. The result is a hot car interior.

Some items that might cause you’re A/C system to malfunction are:

  • The amount of refrigerant in the system has become too low causing the A/C Compressor to stop operating. This is generally caused by extended use without service or a leak in the system.
  • The drive belt that turns the A/C Compressor is loose or broken.
  • The engine is operating at too high of a temperature. Engine cooling fans failing, antifreeze leaks, failing water pump or thermostat can cause an engine to run too hot. The Onboard Computer will shut off the A/C to lessen the burden on the engine.
  • The push button or “knob” control panel in the dash has an electrical failure.
  • The car battery and or alternator is starting to fail or has failed.
  • Lastly, if the refrigerant system has been “over-charged” , the pressure switch can shut off the compressor.

Again, these are just a few examples or possible causes for failure, many more than this exist. Until you get you vehicle to a licensed Automotive Technician, preferably one that specializes in your make of car, you cannot know what my need to be repaired or simply serviced. The cure could be as little as $150.00 verses $1500.00 or more. Don’t wait, have it checked out when unusual symptoms first appear. The longer you wait, the more expensive it may become.
