Engages and disengages the compressor clutch as needed.
It's a cycling clutch compressor. It disengages to keep system pressure where it should be. When it reaches the high point, it disengages. Then it engages again when it reaches the predetermined low point.
Sounds like either a defective relay or relay wired incorrectly switch the wires over.sounds like wires are on backwards
It's supposed to. You have a cycling clutch compressor. When system pressure reaches a predetermined high, a sensor disengages the compressor clutch, and engages it back on when system pressure drops to a predetermined low point. What you're experiencing is normal operation.
solenid switch engages and disengages the bendix on the starter
If the AC pulley is locking up when the ac compressor clutch engages, it's not a clutch problem, it's a compressor problem. But yes, the AC clutch can usually be replaced separately. The problem is, if the clutch is worn out the compressor is probably worn out as well. It usually isn't that much more to replace the whole thing.
Because it engages/disengages the rotating power of the engine from the transmission.
Sounds like you need to rebleed, and set your master cylinder for your clutch, Assuming you have a hydrolic clutch
There is a button on the left hand side of the gearshift just below the handle which engages and disengages the overdrive.
Maybe a bad or loose wire on the compressor? Check the wiring real good for loose or dirty connections. Look for any cracks or breaks too. It's also possible that it's just a little low on coolant and it's a coincidence that you opened the hood and the compressor disengaged. Check the connection to the low pressure sensor and make sure you have enough refrigerant.
It engages and disengages the lock that starts the vehicle. There are 2 parts to the switch. The ignition switch and the lock assembly.
The AC clutch is on the front of the compressor where the belt rides. When power is applied to the clutch it engages to turn the compressor. It is basically a magnet a/c compressor clutch is the ound thing on the front of the compressor with pulley wheel attached. this clutch is an electro magnetic clutch that when electricity is supplied, engages so as the a/c compressor is driven ,which can then pump freon thru the ac system
My guess is that a vacuum line was disturbed that engages or disengages the 4wd.
Well, that depends on exactly how it's fluctuating. If it drops when the compressor clutch is disengaged and builds back up when the compressor clutch engages, that's normal operation.
Tighten the belt. The belt drive the AC compressor. On some cars the compressor engages when the defrost is on to remove moisture from the air before it's heated for the defrosters.
The Air conditioning compressor is likely seized. There is a clutch in the pulley that engages the compressor when the A/C is turned on. You can easily check the compressor (with engine off make sure the pulley has had time to cool off as it will be very hot) Try to turn the most center part of the pulley. If you cannot turn it by hand the compressor is seized. The smoke was MOST likely from the serpentine belt rubbing on the seized pulley when the A/C compressor was engaged. Please note that the same belt drives the power steering pump. This belt will be destroyed from the heat and must be replaced to prevent a possible steering failure.
It's called short cycling. The most common cause is low freon. Take it to a mechanic for diagnosis.
On most of the newer transmissions a electric selonoid is what engages and disengages overdrive and if you havent noticed there is a button on the end of the shift lever on the steering column also there is a fuse have you checked to see if it is blown.
Either a bad pressure switch, a bad pigtail or a restricted receiver drier and block valve.......
The A/C compressor is clutch driven, when electricity is applied to a coil, it engages the clutch. Most likely the coil shorted out in the A/C clutch on the front of the compressor.
The transmission shifts through gears as your engine rpm increases and your transfer case engages and disengages your jeep in and out of 4 wheel drive. Your transfer case also has gears for 4x4 high or low.
The A/C compressor puts an extra load on the engine when it engages. This is most likely the engine hesitation you are experiencing.
Vehicle could have a solenoid type switch to increase idle to compensate for load on engine caused by A/C compressor
There is a relay on the top of the compressor that allows the clutch to engage. Check to see if it is bad by removing the relay and use a wire as a jumper while the car is running to see if the clutch engages. If the clutch engages once the jumper is in place then the relay is bad it cost under twenty dollars to replace.
Sounds like too low an idle, dirty throttle body, dirty idle air control valve, or vacuum leak, could also be pcv valve. This will also occur when a compressor is attempting to lock up... www.acpartshouse.com
