What to do if your Auto air conditioning stops working

 If your car's Auto A/C system stops working, you may be facing a frustrating and expensive fix. Auto air conditioning repair Austin service typically costs between $200 and $500 . Before embarking on that journey or before forking out that kind of cash, take these steps to diagnose the issue yourself.

Check the electrical power

First off, check if there is power getting to the system. If no power is present at the AC compressor connector the cause may be as easy as a blown fuse . The quick way to test this would be to simply swap out fuses until you find one that causes AC power to flow again. They are typically labelled something along the lines of ' AC' or 'Rear AC'. Use caution when removing fuses, make sure they are the appropriate amperage for your vehicle. It is usually printed on the inside of the fuse or on top of it.

Check for low refrigerant

If you have power but no compressor action there could be an issue with the refrigerant system . You can check this yourself by inspecting both ends of all four hoses that lead into the evaporator coil , these are located under the hood in front of each wheel well. Two will connect to a canister containing either R134a refrigerant or regular 134a refrigerant depending on your car's year/make/model, one hose will connect to a vacuum switch, and another two will connect to valves/rier . If any of these hoses are disconnected or punctured, that will explain the lack of compressor action. The fix for this is to recharge the refrigerant system. Please note that if you are uncomfortable performing any of these steps yourself, you should contact a professional. They will have the proper equipment and experience to safely handle your situation .

Check for clogs

The condenser works by pushing warm air away from the engine through its fins using airflow provided by coolant flowing through smaller tubes connected to it called 'radiator/condenser hoses'. If any radiator/condenser hose is damaged or blocked it would prevent this airflow from occurring properly. The Fix here is very much dependent on what exactly blocked off the hose , so you may need to enlist the help of a professional.



Check the blower motor resistor

If all these steps fail, you may have to replace your blower motor resistor which is located under the glove box . This part controls high-speed fan speed at various levels of cabin temperature requirements. If it's blown, then you'll have only two speeds to choose from - 'high' or 'very high'. Replacing this part requires removal of the glove box and the dashboard. Again, if you are uncomfortable doing this yourself please consult a professional.

Wait for help!

If none of these things seem to be causing the issue go ahead and call for assistance .
