How to Fix Your Car's Air Conditioner
A faulty automotive air conditioner can be one of the more difficult issues to diagnose and repair. The first thing you should look for are signs of leaking or an Air Conditioner compressor that does not engage. If the air conditioning system requires substantial repairs, you may not have the equipment necessary to conduct those repairs at home. If it is low on refrigerant, however, you can recharge it using a recharge kit you can purchase at a local auto parts store.
1. Identifying the Issue
⑴Start the vehicle and turn on the air conditioner.
⑵Look to see if the A/C compressor is running.
⑶Check the wiring leading to the A/C compressor.
⑷Look for leaks in the air conditioning system.
2. Preparing to Add Refrigerant
⑴Purchase the correct type of refrigerant for your vehicle.
⑵Check a thermometer for the ambient temperature.
⑶Locate the low-side service port for the air conditioning.
⑷Use a rag to clean the area around the service port.
⑸Attach the charging hose to the low side service port.
3. Refilling the Refrigerant
⑴Turn the valve until you puncture the seal on the can.
⑵Hold the can upright.
⑶Look for leaks.
⑷Remove the charging hose and store the can somewhere cool.
