Why won’t my car’s air conditioning turn on?
The following are some of the most typical reasons why air doesn’t exit your car’s vents: If your air intake is blocked, air from the outside either doesn’t enter at all or doesn’t circulate effectively. The ventilation system has a blown fuse. electrical problems, like a faulty relay.
Disconnect Clutch Oil Cable
High/low oil pressure switches, which guard against the compressor being harmed by unfavorable operating conditions, were one of the factors we covered in our discussion of what can cause the clutch to not engage properly. Disconnect the compressor’s connecting cable from other components to see if it has malfunctioned or not. Measure the battery voltage and the ground by attaching a voltammeter to the connector. You should examine the AC relay and fuse if there are no readings.
Make Sure Compressor Have Sufficient Oil
Checking for a specific level of oil in the AC compressor is one of the requirements before engaging the clutch manually. The glass display within the compressor makes this clear. Make sure it is above the red line to determine the correct level. Add more oil if necessary, following the specifications listed in the user handbook.
Set the Amount of Refrigerant
A specific volume of refrigerant that complies with the manufacturer’s specifications should be present in the AC compressor. The internal compressor elements are put under the ideal load, preventing damage. Utilize the pressure gauge that is mounted on the AC’s high pressure and low pressure rails to measure the refrigerant. It is compared to the suggested value and then balanced.
Jump Start the Clutch
After doing the aforementioned checks, you must be able to manually engage the clutch. Unplug the single wire connector on the front side of the compressor, and then connect a jumper wire to the wire you just disconnected from the compressor. The other end of the jumper will assist in starting the compressor manually if you connect it to the positive wire of the automobile battery.
