Issues with Under Dash Air Conditioning
Under dash air conditioning comes from far more places than just under the dash. These automobile air conditioners are actually a large network of components, all of which work together to shoot cool air from under your dash. For the A/C to work, all those components must be in proper shape.
If something is going wrong with your under dash air conditioning, you'll want to diagnose the problem. Most likely, something is amiss with just one of your air conditioning parts, and it's your job to find out which. A dealer or body shop can do this for you, but they will charge a solid amount of money, and the job is not difficult for you to do on your own.
One problem you could have with your A/C is the power source. In general, the bulk of air conditioning networks have two sources of power, not just one. If you're looking for these power sources, you can most often find them in your car's fuse box.
Another A/C issue you might have is with electrical switches, which can malfunction. The purpose of an electrical switch is to control the current flowing through your A/C system. Most systems have at least two switches, and they must be functioning correctly in order for the A/C to work properly.
