Your ac clutch will not engage what can you do to find what is wrong?

First, check the electric system, fuses, circuit breaker, and connection to the clutch assy. Chances are your refrigerant level is low and the low pressure cut out switch is preventing the clutch from engaging in order to protect the compressor. You can jump across the terminals at the overload fuse to check operation of the clutch but only for a short period of time in case your system is low on refrig/oil. Evacuate and recharge the system.

Ac switch 2002 Pontiac has three prongs which two do you jump to get clutch engage?
Dont jump them, its not a switch, its a transducer and you could wreck your pcm by jumping the wrong one. Run a power wire directly to your compressor to get the clutch to engage. If it doent engage then, it is your clutch. Remember to first check refridgerant level and fuses/relays. Good luck.
Ac clutch wont stay engaged?
low freon
How do you know if AC relay is bad?
Turn on ac and watch clutch on front of ac compressor. If clutch doesn't engage then AC relay is bad. Or you can follow the schematic on the side of the relay and use a volt meter to test it.
Why would the AC clutch not engage in a 1996 Honda Civic?
You could have air in the lines
What happens if the electrical connector is not connected to the ac compressor?
The a/c clutch will not engage and the compressor will not come on.............
Why wont AC clutch engage on 1998 escort ZX2?
Most Likely Low With Freon.
No Ac 2001 Chevy Malibu?
check fuse or ac relay in under hood fuse box.. if out of coolant ac clutch will not engage,this is a safety feature!!
What causes a 1999 Jeep Cherokee to start vibrating only when the AC is on after the AC blew cold air then warm air before a pop was heard?
Check the belt and pulleys. Make sure the AC pulley turns. When the AC is turned on, the clutch should engage to the pulley and the AC compressor should turn, and yes, it can cause the engine to vibrate a little. If the clutch doesn't try to engage, there could be some problems with the AC, but first try to find out what caused the noise, and determine if the AC compressor is turning.
What is wrong if the AC on a '98 Dodge Caravan won't operate unless you tap the AC clutch relay?
That sounds like a sticking clutch relay.
If the AC compressor clutch does not kick in and the relay and fuse are ok what could be the problem?
The clutch receives it's signal to engage from a pressure switch in the system. If there is insufficient refrigerant in the system the pressure switch will not close resulting in no power at the compressor clutch to make it engage.
How can you check all possible fuses and relays that would cause the AC clutch not to engage on a 1993 Buick LeSabre?
First, the clutch won't engage if the refrigerant level is low. Start there. Next, check the sensor at the receiver/dryer.
How do you test the ac compressor?
You should be able to hear it engage-there is a clutch. If not, check the hot wire when someone turns on with a test light. If it has juice & does not engage, you may have a problem.
