Within this short auto repair post, his experience is shared by a master automotive technician, derived from working on air conditioners in Florida for the past few decades. As it is to a consumer that understands the worth of being advised in regards to dealing with car repair shops this free information could be equally useful for the doit – yourselfer. Read on for free auto A/C help once the atmosphere is blowing warm on ONE side.

Usually cars that blow cold on one phase of the dashboard and warm on the opposite side, are commonly furnished with a dual zone climate control system. Dual zone systems enable respective temperatures to be adjusted by the driver and front passenger for their comfort levels. There are only two common factors behind a temperature difference when both sides are set in the settings, lets cover the very first one.

Low Refrigerant

Automotive air conditioners which use 134A, generally carry a modest amount of refrigerant compared to older autos that use R12. Truck and auto air conditioners now are a lot better than their old counter parts. The reality that 134A less freon is used by systems, means that a flow can more immediately change the operation of an HVAC (Heating Ventilation & Air Conditioning) system. As a result of composition of double AC apparatus, low refrigerant is the leading cause of extreme temperature difference from one phase of the dashboard to another. Even well seasoned car mechanics might be amazed to discover that as little as 4 to 8 oz undercharged of 134A can make such a big difference. The temperature in the left vent to the correct vent can vary 10 to 20 degrees. The simplest thing to try would be to recharge the unit with all the factory specified quantity, remove all freon and top off the machine or better yet. In many cases following the appropriate charge of Freon is really in the automobile, the temp will blow equally as cold like it should on BOTH sides!

HVAC Door Problem

Double zones furnishing different temperatures from ports on each side of the dashboard is attained by using little doors inside the HVAC housing. By controlling the doors, the temperature of the atmosphere to the right and left could be adjusted to the desired comfort level. Often the motor (or actuator) that controls the doorway for either side can neglect or the doorway itself can stop and break the temp. from being adjusted. Diagnosing this difficulty is more complicated and will become a subject for a different post. Thank you for reading.
