A/C Problems Demystified

June 30th, 2016

Believe it or not, the A/C system in your vehicle is fairly simple in principle and design. Like your refrigerator, it operates on a cycle of compression and expansion of a gas, known as refrigerant. The compressor turns the gas into a liquid, and as the gas evaporates it provides cooling. Like your refrigerator, its main components are: 
 
  • Compressor
  • Condenser 
  • Receiver/dryer
  • Thermostatic expansion valve
  • Evaporator
  • Refrigerant

Flats vs Blowouts

If you get a blowout, you'll know about it right away. Sometimes the tire can fail dramatically, with a bang as loud as a shotgun going off. Other times, it might just be a loss of air and a sudden change in your car's handling, followed by vibration, noise and a pull to one side. If it's a front tire that fails, your car might be a real handful to drive until you can get to a stop.

In either case, your first job is to pull off the road as quickly (but safely!) as you can. Don't jam on the brakes or make any sudden m ...[more]
