Why does my Jeep Liberty clutch not engage?
The AC clutch on my Jeep Liberty 2006 won’t engage. Here is what I have checked so far. When I jump the AC relay I am able to engage the compressor and get cold air, pressure at rest is about 105 pounds at 60 degree F. When the compressor is running it drops to 35 psi.
Why is the a / C compressor not engaging in my Jeep?
I can easily turn the compressor by hand so it doesn’t seem to be seized. I removed the A/C clutch relay and tried using a jumper wire to engage the clutch/compressor but with the 5 prongs on the relay I wasnt sure which ones to jump together.
Why does the a / C compressor clutch not engage even?
The a/c compressor clutch will not engage even when I jump the low pressure switch thats mounted on the top of the accumulator (dryer). Is there another method such as direct from the battery? There are two wires goin into the compressor instead of one so I am unsure of how.
Why is my a / C CLUTCH not working on my Dakota?
When it is intermittent, it is probably more wiring or sensor related. Those intermittent problems are always nice to solve. Don’t read too much into it, I just replaced an A/C compressor on a 4.7l dakota last week that took a couple trips of the customer running over here when it was acting up so I could actually see the problem.

What to do when Clutch won’t engage?
So you need to use a paper clip to bypass the relay switch and force the clutch to engage. You can then recharge the freon and re install the relay switch and it will sense more pressure and the clutch will engage by itself. Loading…
What to do if your Subaru clutch is not working?
Check the condition of the hose from the brake fluid reservoir to the clutch master cylinder and look for any fluid leakage. Also check for leaks in the fittings surrounding the master cylinder and the hose from the master cylinder to the slave cylinder.

Why does my Subaru Legacy clutch make noise?
Noise could also mean the clutch disc is going bad with a broken spring or a bad rubber diaphragm. The clutch would also need replacement in this case. If the bearings are going bad and causing the noise, the clutch must be disassembled to replace them.
What happens when you change the clutch on a Subaru?
A dragging clutch won’t allow you to disengage it to change gears; a slipping clutch disengages easily, but won’t re-engage right when you ask for a new gear. Instead of smoothly shifting into the next gear, you may hear a whining or sliding noise as the engine revs high. Even though the engine is racing, you won’t get much acceleration.
What happens when the AC clutch does not work?
An automobile can have numerous serious problems and a dysfunctional AC compressor clutch is one of them. When this component does not work properly, the engine does not get the cold air flow – leading to some major complications. Knowing how to manually engage AC compressor clutch will help you skip a visit to the mechanic.
How can I test my Subaru Legacy clutch?
Test the master cylinder by pushing down the clutch pedal while someone else watches the level of the brake fluid reservoir. If the level of brake fluid rises with the clutch depressed, the cylinder is faulty.
What to do about clutch master cylinder in Jeep Liberty?
Bleed all air from the master cylinder. Test drive the vehicle. During an oil change, the mechanic should check the amount of brake fluid. If you feel a change in the way the clutch pedal feels (softer pedal) when stepping on it, you should have a mechanic inspect the clutch master cylinder and hose.
How does an AC compressor clutch receive power?
AC compressor clutches receive power in a number of ways. They can activate through a relay that’s energized directly by a proper condition of the low and high pressure switches. Or, the relay can be operated by the PCM which has interpreted the condition of the low and high pressure sensors.
What happens when the clutch pedal is depressed?
When the clutch pedal is depressed, the fluid is transferred from the clutch master cylinder to the slave cylinder, which provides the pressure needed to engage the clutch. If the clutch master cylinder is leaking, it won’t hold the proper amount of brake fluid, and there won’t be enough pressure from the fluid to engage the clutch.

What kind of transmission does a Jeep Liberty have?
There are two versions of the Liberty. The KJ series which was produced from 2002 to 2004, and the KK series introduced in 2005 to the present. There are four wheel drive models and two wheel drive models. Two types of transmissions are available for the Jeep Liberty, a five speed manual transmission, and a 4 speed automatic.
What causes gears to chatter in Jeep Liberty?
Insufficient gear oil due to a leak can cause the gears to chatter. Check the transmission oil seal or vehicle speed sensor O-ring. Drive the vehicle and check for gear slippage, noise or no drive in forward or reverse gears. Lack of automatic transmission fluid can cause these issues.
When did the Jeep Liberty KJ come out?
There are two versions of the Liberty. The KJ series which was produced from 2002 to 2004, and the KK series introduced in 2005 to the present. There are four wheel drive models and two wheel drive models.
Why does my AC compressor clutch not engage?
Why AC clutch won’t engage If the clutch doesn’t engage, the problem could be a blown fuse, an open in the wire to the clutch coil, a bad clutch coil, a poor ground, or a low pressure lockout. AC compressor clutches receive power in a number of ways.
How is the compressor clutch relay turned on and off?
In some vehicles the compressor clutch relay is turned on and off by the low pressure switch and the evaporator temperature sensor. In a computer controlled system, the compressor clutch relay is grounded by the computer. If the fuse is good, disconnect the electrical connector from the compressor clutch coil.
Why is my a / C CLUTCH not working on my Jeep?
I checked the fuse and relay in the PDC, jumped the low pressure switch, and confirmed 12-13 v. @ the compressor clutch. Is it safe to say the a/c clutch is my culprit? Should I try energizing it direct from the battery to confirm or…???? Any help or suggestions from the WJ Gurus here is greatly appreciated.

Why is the pulley on my AC compressor not working?
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.

Where are the fuses located in a Jeep Liberty?
The electrical power distribution center is located in the engine compartment near the battery. This power center houses plug-in “Cartridge” fuses that replace in-line fusible links.
What happens when I jump the AC relay?
When I jump the AC relay I am able to engage the compressor and get cold air, pressure at rest is about 105 pounds at 60 degree F. When the compressor is running it drops to 35 psi. I can’t check the high pressure side because I don’t have a gauge for it. If I jump the low pressure switch nothing happens.
Why does my car clutch not engage when low on refrigerant?
That’s why car makers install a low pressure switch–to prevent the compressor from running if the system is low on refrigerant. 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.
Why is my air conditioning not working on my Jeep Liberty?
Dana Dowling/Demand Media The air conditioning system in your Jeep Liberty compresses a refrigerant and blows the resulting cold air into the passenger cabin. When this system is not working properly, it can be because the pressure in the AC lines is too low, or because the compressor has failed.
Where is the air conditioning line on a Jeep Liberty?
The air conditioning lines will be steel lines running on the left side of the engine bay. The low pressure line on your Liberty is marked with a blue valve cap on the line. Unscrew the blue valve cap and screw on the air conditioning pressure gauge. Turn the knob on the pressure gauge counterclockwise to allow pressure into the gauge.
