I have 2011 Nissan Sentra. Yesterday the a/c worked fine. Today it blows only hot air (compressor not engaging). I checked the freon, it's good. I'm lost.


If your fuses are all ok, there is a good chance the climate control unit has failed (the piece with all of the dials and buttons).

My AC is not blowing cool air. Compressor clutch is not getting engaged. AC button is showing green light indicator though. I am suspecting clutch relay problem. where is air conditioning clutch relay in...


First of all check the freon pressure, if the pressure is low the compressor clutch will not turn on. The pressure should be between 30-40 PSI.

The AC clutch won't engage on my 2003 Hyundai Sonata SGX. It engages when i run a direct wire from the batter. I checked the voltage to the compressor through the wiring and it's about half a volt. ...


as with any electrical diagnosis you always want to check fuses and relays, but it sounds like 1 of 2 things......... you ethier really low on freon, causing it to cut off the clutch to save the compressor from damage due to lack of oil, (the lack of freon would indicate a leak in the system) Or your clutch switch is bad. resistance of .5 is normal, check the voltage from the harness, should be around 11.45 volts with engine running, if it s not then check your fuses, or relay also look for shorts in the harness along the path to the relay. if your checking the switch itself resistance should be around .5 like said earlier, but check a refrence manual to be absolute. but im sure its low freon or bad clutch switch.

2000 chevy truck 5.3 liter. air conditioner works 10-15 min then stops. clutch and clutch pressure switch good, freon level good, batt and alternator good??


After the clutch disengages ( when it's not suppose to )check the voltage on the + output terminal on the clutch relay, (inside the fuse box under the hood) if you have voltage there, check the voltage at the clutch, if you have voltage there too, its the clutch. The clutch gets worn and will engage when cool,but fails after heat builds up. Check this by tapping the face of the clutch with the ac on, if it's simply a worn clutch it will likely engage for a while.

Clutch won't engage on air conditioning compressor


The air gap may be too wide between the clutch disc and plate. It usually happens from wear. You can test this possibility by engaging the clutch electrically as you have done and then push on the disc slightly with the handle of a hammer or screwdriver. Be careful not to get your hand or fingers too close while the engine is running. Basically you are helping the magnetic field pull the disc in. I hope this helps.
