If the pulley is seized and you don't want to replace it with a new or reman one, there may be a few options. One is bypass the compressor completely. follow how the belt travels around the pullies, and how it would run if you just don't put it around the compressor. IF the compressor interferes with the travel then you can't. So you may want to consider a used one from a junkyard. If the compressor does not interfere, and the travel direction of the belt is possible, take a string and wrap it around exactly how the belt will go and by pass the compressor. Measure the string and take the original belt to the part store and tell the you want a belt like that but only "what ever the length of the string is" long. Some cars do not offer A/C so there may be no listing for one that doesn't have a/c. If the compressor is seized, replacing the pulley may not be an option. buy a belt for one with no AC there is no way to bypass this i have tried although they sell a pulley called a help pulley for 30.00 i put it in mine works fine
Typical causes of a compressor not running are: low coolant, blown fuse in compressor circuit, bad compressor, bad temperature sensor.
Check for a blown fuse. Also check the wiring connections at the compressor.
If the compressor will not come on at all, it is not because the system needs charging. Check for a blown fuse, disconnected wire at the compressor, or a defective compressor clutch.
check to see if your fuse is blown.
Assuming you are asking about the ac compressor, there would be two possibilities, blown fuse or low on freon.
Coolant overflowing from a 2003 Cavalier overflow tube usually indicates a blown head gasket. Check the cylinders for proper compression to confirm a blown gasket.
Could be a blown fuse or low refrigerant charge
Blown fuse, low of refrigrant, defective compressor, or compressor clutch.
Blown Fuse, defective compressor clutch, or relay, low of refrigrant, bad compressor, etc.
Low refrigerant charge? Blown fuse?
It is best to, but they can be blown on with an air compressor.
When you trun on the AC two things should happen, Your Compressor Pulley should engage and your radiator fan should turn on. This can be a few problems. One of the most common problems is that your AC compressor pulley is not engaging, this pulley had 3 small circles on it. When you activate your *AC* option, the compressor pulley should engage with the pulley that the belt is on. If not then you will not get AC, only your fan. Now does your AC feel fine when your moving but then suddenly warms up as you stop? If this happens then your condenser fan (or radiator fan) is not running. This is because heat is not being blown off the freon and it will not be very cold or cold at all when it enters your AC evaporator (where the air is cooled). In this case you should leave the AC off or else it can put the compressor under excess high pressure and can cause it to fail prematurely. The last problem is that you might simply be low on freon. If this is the case, make sure to have your AC checked for leaks before being recharged. Dave.
Bulb is most likely blown
Low refrigerant? Blown fuse? Bad compressor?
If a Chevy Cavalier cigarette lighter doesn't work, check the fuse. The fuse may be blown and will need replaced.
Check for a blown fuse. If fuse is OK, see if the wiring at the compressor is OK. Clutch may also be defective. If the compressor comes on and off intermediately, it is low of refrigerant.
blown engine, out of gas janitorial duties.
It COULD be a blown fuse. Check the fuse panel. It COULD by a blown flasher unit. If the fuse is OK, change the flasher.
you may have a blown head gasket or a cracked block
Do you mean the compressor? If its not coming on either its seized or the a/c relay is blown.
Maybe the compressor clutch is not being sent power from the switch in the cab. I'd yank the panel out and have a look at the switch. FriPilot
If the compressor is not coming on at all it could be that you are low of refrigerant and just need to add some more.
check engine oil for water and check radiator for oil
Remove the head and replace the gasket. No other way to fix it.
Blown Head Gasket or Bad Cylinder Head
