Ways to Troubleshoot an Automobile Air Compressor 1Start the automobile and turn the air on. If there exists a scraping, tinny sound just when the compressor is turned on that goes away as soon as it is turned off and also the compressor is still good, the clutch requirements to be replaced. The clutch might be replaced without having discharging the A/C program if it really is accessible. Just take away the belt and leave the compressor mounted towards the engine.2Check the clutch operation if it does not come on. Apply power directly for the wire on the top front of the compressor. If it comes on diagnostics car tool, then there is an electrical problem to be traced. If it will not come on, replace the clutch.3Listen for any rather loud knocking noise because the compressor operates.

It the noise goes away when the air is turned off, the compressor is about to self destruct internally and needs to be replaced as soon as possible. Do not use the air till the compressor is replaced because the vanes inside the compressor are coming apart plus the more it is run the far more material it'll release in to the method, causing a blockage. This could get really high-priced if each of the parts require to become replaced inside the air conditioning method.4Hook up the gauges towards the A/C method and turn the air on. When the compressor doesn't come on, check the pressure on the gauges. The blue or low side needs to be around 75 to 80 pounds in an effort to operate the low side switch to kick the compressor on. When the pressure is below 75 pounds the technique requires to become charged as a way to get the switch to activate, permitting the compressor to perform. The low side switch is installed so that if the pressure (as inside a leak) drops, it shuts the compressor off, stopping harm to it. In the event the pressure is appropriate and in range then an electrical trouble is present.5Check the low side switch for energy with all the air on. If there is power, jump the connector and see in the event the compressor comes on.

If it does, the switch is poor. If there is absolutely no power, check the fuse for the air conditioning within the fuse relay box below the hood. Verify the relays by pulling them out and checking the terminals for power at two terminals. If there's energy at only 1 terminal, the problem is inside the cabin. If it has power at two locations, the relay is negative.6Check the gauges when the air comes on and doesn't awesome. The right readings will differ a little bit with all the outside temperature, but should really be close to 25 to 40 pounds on the low or blue side and 210 to 250 on the red or high side. If both sides are low plus the compressor is working, the program needs to become charged. In the event the high side is low as well as the low side is high, the compressor is no superior. In the event the high side is high along with the low side is close to typical Vehicle Diagnostic equipment, there's either a blockage inside the expansion valve or orifice tube, a radiator fan not working or a plugged up condenser.
