You may have burned it up. AC compressors need oil initially.
Usually the compressors require additional lubrication during the installation. The warranty on compressors usually require the replacement of the dryer (Accumulator), orfice tube, and flushing the system. This will eliminate debrie and contaminates from damaged compressor in which was replaced. The compressor may be checked for the grinding noise by the following procedure. Disconnect the battery ground. Remove drive belt from clutch. Place wrench on nut in center of clutch and rotate slowly clockwise. If the shaft doesn't rotate smoothly there is likely damage inside the compressor cylinders and pistons. If the compressor checks OK, check other components while the drive belt is disconnected. For example, The pulley on the alternator, idler pulley, and water pump should not have any end play. The AC compressor puts a heavier load on the drive belt and may cause other components to make noise. The only other possibility that comes to mind is that the compressor clutch bearing is bad or the clutch is slipping. ! Good luck!
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.
The ac could be causing the problem. Turn the ac off, and watch the compressor clutch to see if it is not engaged. If it is then the compressor or clutch could be bogging the engine down.
It depends on where the grinding noise is coming from. Most of the time the grinding is coming from the brakes and the brake pads need to be replaced. If they've been grinding for a while, the rotors will need to be resurfaced or replaced. Other possibilities for grinding are worn axle bearings, or a problem with the clutch. If the clutch goes out, there will be a grinding noise when you try to shift gears.
if its locked, it has a serious problem and probably needs replaced
The problem could be the relay that goes to the compressor this could be faulted out causing the compressor to run constantly. However if this isn't the case then a quick check of the fuse may also resolve the problem.
sounds like elec problem, meaning power engaged and is in "on" mode or bearing shot if you mean by hand
not enough collant . water valve in heater hose could not be shutting off and letting hot water flow through the heater core. compressor not staying engaged.
I am having the same problem, if you figure it out before me let me know!! ryanthaking@yahoo.com. Thanks.
Same problem and question, compressor locked up. Battery won't keep a charge. Does the belt send charge to battery?
Ihad the same problem on my 1997 Tahoe last year and i just replaced the brakes and also the springs and the piece that pushes the pads out (i forgot the name of that part)
If the clutch is engaged & turning, there should be no problem getting freon into the system, unless the orifice tube is plugged.
Teeth grinding can be a problem, since it removes the protection on your teeth. There are available treatment options that can repair the damage. There is also treatment to get you to stop grinding your teeth.
