A/C problems

from an old post by Oldmaster: With the air conditioning season rapidly approaching, there will be many posts here asking for advice. Here is a site that explains A/C operation, diagnosis, repair, evacuating, and charging procedures: http://www.polarbearinc.com/Trouble1.htm. It is extremely thorough and very detailed. When the air conditioning system in your vehicle is operating properly, it can be your best friend. When it needs attention, it can be your worst enemy. Using improper procedures can cause poor A/C performance, destroy components in the system, harm the environment, and it can seriously injure or KILL you! If you do not have the proper equipment, are not familiar with your system, or the procedures involved with diagnosing and repairing it, or you are just not comfortable working on the system, take it to a professional.
