The Subaru AC clutch not engaging is a common problem. It occurs when the compressor pulley driveshaft becomes misaligned with the crankshaft, preventing it from fully engaging and allowing air conditioning to cool your car. The cause of this misalignment can be due to wear on certain components, such as the belt tensioner or idler pulleys, which can become worn over time.
In some cases, incorrect installation of these components may also be an issue. Diagnosing this issue requires checking for proper alignment between these parts and replacing any worn components before attempting to re-engage the compressor clutch. Additionally, ensuring that all connections are secure and free from obstruction will help ensure proper engagement of the compressor clutch in order for your vehicle’s cooling system to function properly.
If you own a Subaru and have been experiencing issues with the air conditioning clutch not engaging, it’s important to take action right away. Not only is this an annoyance in hot climates, but it can also cause further problems if left unchecked. In some cases, the issue may be as simple as needing more refrigerant or replacing a faulty switch, but other times more complex repairs are needed.
If you’re having trouble getting your AC system up and running again, make sure to contact a certified technician to diagnose and repair the problem for optimal performance.

What Would Cause an Ac Clutch to Not Engage?
An AC clutch is a critical component of an air conditioning system, and if it fails to engage, the entire system may become less effective or even fail completely. The most common cause for an AC clutch not engaging is when the compressor’s internal pressure falls too low. This can be caused by any number of issues including a clogged filter, dirty condenser coils, insufficient refrigerant levels, or age-related wear on the compressor itself.
In some cases, faulty wiring or electrical components can also be at fault; such as corroded terminals in the connector plug between the engine and compressor. A qualified technician should always perform a comprehensive diagnostic evaluation to determine what has caused your AC clutch not to engage before attempting any repairs.
How Do You Force an Ac Compressor Clutch to Engage?
To force an AC compressor clutch to engage, there are a few steps that need to be taken. First, make sure the power is on and the refrigerant pressure is correct. Then check for any possible electrical issues such as loose or damaged wiring connections or a faulty relay switch.
Next, remove the drive belt from the pulley and inspect it for signs of wear and tear. If everything looks okay, then use a multimeter to test the AC compressor clutch circuit for continuity between terminals C1 and C2 – if there is no continuity then this indicates an open circuit which will require further investigation. Finally, replace any faulty parts identified during testing before attempting to force engagement by rotating the pulley with either your hands or with an appropriate tool such as a socket wrench.
How Do I Know If My Subaru Ac Compressor is Bad?
If you own a Subaru and are wondering if your AC compressor is bad, there are several signs that can help you determine whether or not it needs to be replaced. One of the most common symptoms is when your air conditioner fails to blow cool air. Moreover, if the cabin temperature does not change with the adjustment of the thermostat, then this could indicate an issue with the AC compressor as well.
Additionally, strange noises coming from underneath your hood may also be indicative of a failing AC compressor and should be investigated further. Finally, if one notices any oil leakage under their car near where their AC unit is located, then this may point to an imminent failure in their system’s components as well. If these warning signs are present in your Subaru vehicle’s A/C system, it would be wise to have it inspected by a qualified mechanic right away in order to identify any potential issues before they become worse and require extensive repair work or replacement parts.
How Do You Know If Your Ac Clutch Relay is Bad?
To determine if your AC clutch relay is bad, there are several tests you can perform. First and foremost, check the fuse box to see if the proper fuse is inserted and in good condition. If it’s not, replace it with an identical one from a trusted auto parts store.
Secondly, apply 12 volts of direct current (DC) to the two terminals on the relay using an automotive jumper cable or any device that can provide DC voltage. This should cause a clicking sound from within the relay which indicates that it is working properly. If no sound comes out then you probably have a faulty AC clutch relay and need to replace it with an exact replacement part for your car make and model.
Lastly, use a multimeter or other electrical testing device to measure resistance between both terminals of the AC compressor clutch when its engaged; this should be around 10 ohms which tells you that everything is normal and working correctly. If not then again you may need to change out your old AC clutch relay with a new one as soon as possible so your air conditioning system will start working again!
