If you do not use, or do not need, nor intend to use a/c for a while, go to your mechanic and ask to have the a/c pump removed, and install a replacement pully and bypass belt. You can always add a/c back later if you want or need to. Otherwise, like in the previous answer, sounds like the bearings are froze up and this fix will should be cheaper than replacing the a/c pump.

It sounds like the bearings in the compressor are shot. Try to remove the drive belt from the pulley and see if you can spin it by hand. Even if you can there still may be a problem with either the bearings or race. You would probably have to replace the compressor. Good luck

SOURCE: 2000 Montero Sport A/C doesn't work

The problem is there is a leak in the 134-a refrigerant system and the level of refrigerant is low so, the low pressure sensor is reading too of a low pressure in turn causeing the low pressure switch to turn the power off leading to the compressor.

SOURCE: on a 2003 mitsubishi montero sport w/ 3.0 v6 a/c belt squeals

Your belt is loose (and it just needs tightening) or it is worn and needs to be replaced. It may look ok but they glaze over; all the little ridges get shinny and slip.

SOURCE: AC COMPRESSOR

Get the gas pressure checked, if it is low the power is disabled to prevent damage (the gas carries the lube oil so no gas-no oil) you can buy cans and adaptors to top up yourself, the often have the correct oil and a dye to find leaks.

SOURCE: I have a squeaking sound

once the belt become loose it slips and its friction surfaces become damaged .. even if its then tightened properly it may still slip .. an old damaged belt should be replaced and tensioned properly ... its common for older type belts to slip and make noise .. it is not as common in later cars since they often have automatic belt tension and improved belts .. any slipping is a sign of some other problem ... one frequently seen problem on some cars is a pulley that is spring loaded to keep the belt properly tightened .. the pivot on the pulley freezes up and no longer maintains proper tension .. those pulleys can sometimes be re lubed but often are hopelessly frozen and need replaced ... also other pulleys and the alternator bearings can start to make a squeaking noise when the sealed bearings lose there lube .. you can put a drop of oil on each bearing to see if one quiets the sound ..

Where is my a.c. compressor replay fuse at for a 2000 montero


It is doubtful the fuse is an issue, check the refrigerant charge in the AC system, if it is low the compressor will not engage. You can jump the low pressure switch to turn on the compressor, that will verify the electrics are all ok. The switch is located in the low pressure AC line from the compressor on the engine, it is the larger of the 2 lines coming from the AC compressor.

How to turn off air compressor on 1999 ford expedition


  • Under the hood in the relay panel will be a relay for the compressor. When you locate the relay box look on the underside of the lid for the legend (layout) of the relays. Pulling that relay will stop the compressor from turning on.
  • You can also just unhook the connector on the compressor and secure it to stop the compressor from turning on.
  • If you need the compressor clutch to not turn at all, like if the bearings are bad, then you need to buy a smaller belt to bypass the compressor all together.

  • Hope this helps and thank you for using FixYa.

Can i run a 2003 montero sport without the ac belt?


You can run any car without a belt around the AC compressor, BUT it is likely to cause the compressor to freeze up you do it for to long. So if your AC compressor is operational, I wouldn't recommend it.

it means that your crankshaft pulley comes out and the crankshaft key must have gone off thats why it shreds the belt due to misalignment. you need to pull down the complete belts, cooling fan to pull down the pulley using a puller to investigate the problem.

The AC unti is driven by a belt coming from the crankshaft. The belt is attached to the ac compressor which has a clutch unit that is suppose to let the compresser pully spin freely. by the sounds of your problem you might need a new pully/clutch for your ac compressor

2006 ford fusion ac problem


As a Ford dealer tech I found this was always caused by the AC compressor cycling switch, it shuts the compressor off when it reaches about 30 PSI, this prevents freeze up and saves fuel, when the system press rises again to about 42 PSI it turns the compressor back on and so on, change the switch, it is located in the low pressure line from the compressor, that is the one that gets cold.
