Magnetic Clutch Relay location ?

If its low on Freon it will not click on . It has a low pressure switch shut off . Or control panel not sending current down stream to clutch

aircon gas needs topping up.

Stand by the gas tank while someone turns the key to ON. Listen for the fuel pump to come on for a second or two as it should. It will only come on for about two seconds to pressurize the fuel system, then shut off and only come on again when the engine is cranked. If you hear it, then the pump is working. Hence, you would smell gas after cranking the car a bit. If no sound from the pump, look for the relay in the power distribution box under the hood. The box's cover should have a diagram for fuel pump location. Or your owner's manual might show it.

Look under the car when it stops and after the engine is turned off, do you see a lot of water dripping under the car on the passenger side? If so the AC evaporator core is freezing up and the pressure switch is defective. If scenario this is not the case then you may have either a sticking compressor magnetic clutch relay or the magnetic clutch closing coil is shorted when it is hot.

Check the MAGNETiCiC CLUTCH on that compressor! Just pull out the the power connector and directly put it on the (+) terminal, u will hear a clicking sound, thats the magnetic clutch engaging! If u didn't hear anything, magnetic clutch is busted and needs to replace it, if there is available part near ur place! U need an A/C technician to do the job!
Taah!

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

Keep us updated.

You have to start by testing the pressure in the system. If it was cycling a lot and then quit it sounds like you developed a leak somewhere and once it fell below the low pressure switch it will not come on.

The system works with a high and low pressure switch that will cut out if the pressure is too high or low. When the system looses pressure it will fall below the low while running, turning off the compressor, When the compressor is off the high side and low side equalize out bringing the stationary pressure above the low limit, turning the system on again. This cycle will repeat until there is not enough pressure when equalized to turn the system back on.

If the pressure is good, go next to the relay, it should be located on the fire wall. if the relay is right, then you need to determine if it is high or low pressure switch shutting it off. IF it is the high, you probably have a restriction in the system, You could also have a problem with the compressor. With the car not running manually turn the clutch and see how much play, smell the area and smell if there is a burnt odor, then try to turn the armature that goes into the compressor. see if it is frozen.

is there a vent shutoff ? You will probably have to search under the dash for a leak in the duct work.......???

hello,hoping your freon is full,check your fuse for air con system,maybe your pressure sensor in your dry tank is defective, check your aircon relay in back of your battery,pull out,check if have burn smell,before you replaces the relay try to check first the resistance of your magnetic clutch,ty

Replace your magnetic clutch relay.
