Magnetic clutch relay

Its controlled by the air con ecu

Check for low Freon....Pressure Switch in the Acumalator is what latches the Compressor Clutch Relay ....Low side line should sweat all the way back to the compressor when full....Never apply voltage to Clutch or other components as This system is pressurized and explosion and frostbite hazard exist....Always wear safety glasses as well.........The system will have to be evacuated to change the afore mentioned pressure switch....Be careful.........

Most aircon system in any car usually has a sensor relay that the compressor will not continuously run if the thermostat are worn out ,if the clutch pack magnet wiring are grounded or worn out,if freon are low ,to find out which one is the problem go check the single wire connected to the clutch magnet right in front of the compressor where pulley and belt are located ,if you don't have a tester to find our that power are present all the time while. Using the aircon,you can bypass and hook another wire on it and hook it in the positive side of the battery ,while running the engine and aircon visually check the clutch magnet of the compressor if it will pop up ,if yes you have a worn out compressor magnet.

If the Freon is low then the a/c clutch will not cut on.There should be a fuse box under the hood and the relay will be in it.

The compressor magnetic clutch is located and attached to the front of the AC compressor and the engine drive belt goes over it

aircon gas needs topping up.

I would replace the item that is cheaper

Where is the a/c relay

Check in the Fuse Block, under hood, generally called A/C Clutch relay, also have an A/C fuse.

Keep us updated.

check for power at compressor clutch if power and earth there is ok new compressor required. no power there check relay and fuses swap air cond relay with another one that looks the same in under bonnet fuse and relay box
