DIY recharging kits tell you to recharge through the low pressure port while the compressor is engaged. But if the system is low on refrigerant, the clutch will never engage. This is a catch 22.
How To Manually Engage AC Compressor Clutch: The Easiest Methods
Knowing how to manually engage AC compressor clutch will help you skip a visit to the mechanic. Plus, you should also know how to examine the clutch to find out if it is faulty or not.
Set all air conditioning controls to the MAX before kicking off the engine. Check the front side of the clutch to examine its condition. Also, find out whether the clutch and the pulley are spinning. If only the pulley is rotating, the compressor clutch is having an issue, which could be stemming from several sources – a blown fuse, bad clutch oil, low-pressure lockout, or an open wire in the oil.
Before starting the next step of diagnosis, you should know that a low-pressure switch can create problems with the compressor clutch’s relay in some car models. The system’s computer keeps the relay grounded but it can go on and off due to the bad switch. A careful inspection of the system and its components will help you to pinpoint the source of trouble.
In this step, you have to detach the connector cable from clutch oil. Keep it safely away from all other components. Use a digital voltmeter to measure the ground and voltage of the battery at the detached connector cable.
What is the most common reason for an air conditioning compressor not to engage? Low level of refrigerant. When the coolant level in the system goes down, the low-pressure switch does not allow the compressor to rotate.
How to manually engage AC compressor clutch when the system is low on antifreeze? Easy. Just adding refrigerant will solve this problem. If your car is compatible with R134a type of refrigerant, attaching a can to the system will override the low-pressure switch and restore the normal function of the compressor clutch.
Unplug the single wire connector on the front side of the compressor. Take the fused jumper wire and connect its one end to that side of the wire connector that was connected to the compressor.
Attach the other end of the jumper wire to the positive terminal of the battery. It will supply the battery voltage to the compressor clutch, allowing it to engage manually. There is no need to switch on the air conditioning system for this method to work.
Jumping the relay is actually very easy. The method shown in this video is for a 4-prong relay, but if you have a 5-prong relay, the method is still applicable, it's just that you might have to find the diagram for the relay. Be sure to jump the copper side, not the gold side. Using a paper clip is easier, simpler and more convenient but we suggest using an insulated wire in order to avoid potential fire hazard and short circuit. Don't leave it connected too long to try and recharge the system, you risk serious and even catastrophic compressor damage.
Even though the demonstration is on a 2010 Honda Civic, they should be similar to other Honda and Acura vehicles such as Accord, CRV, Element, Pilot, Odyssey and other models, domestic and imports.
