Why Is My Cars A/C  Blowing Warm Air     The most common cause Is a low refrigerant charge.  This happens due to a leak in the system.  None of the A/C components will work correct without the proper refrigerant level.  A faulty condenser can cause excessive pressure and disable the A/C compressor.  Causes of restricted air flow through condenser may be from a fender bender, or road debris.  Another common cause is a A/C compressor fault.  A compressor is the heart of the system.  It can not operate with an electrical fault.  Compressor issues tend to happen after long periods of activity.   To find out what's going on in your A/C System you can schedule an A/C Service with us at Rochas Automotive.
