It is under the hood on the accumulator.
It is on the acumulator.
On the top of the drier at the passenger side firewall Wrong the pressure switch is on the ac line under te air cleaner assl. There OS no drier on the fire wall it is before the switch .
Possibly the pressure cycling switch.
The ac pressure cycling switch is designed to engage or dissengage the clutch to keep the proper pressure in the system.
The most likely cause is the system is low on refrigerant. The second would be a defective pressure cycling switch.
Its on the a/c accumulator located on the drivers side better seen from under the vehicle.......
the relays are on the engine side firewall. The compressor relay signal comes from the main computer through the pressure cycling switch or switches.
The system has pressure on it but the switch can be screwed off. A schrader valve prevents the loss of refrigerant. Install the new one after you have put some Air conditioning oil on the O ring seal.
Check the low side pressure switch, the pigtail, the compressor clutch itself and then check to see if you still have an air gap between the hub and the clutch when the system is turned off.........
Engages and disengages the compressor clutch as needed.
The low pressure cycling switch is on the low pressure line coming from the compressor. Most of the time, it will be located on the reciever/dryer. It will have two wires coming from it. The low pressure line is the bigger line of the two.
Under the hood, passengers side next to the firewall on the suction hose....
