Somthing to do with the AC.
If it's a creaking noise then it is most likely that your compressor is broken.
A/C compressor? A/C compressor?
The A/C system compressor operates when in the defrost mode. If the noise is also heard when running the A?C it is more than likely a problem with the compressor/pulley.
Compressor is unbalanced as the rpm's drop.
You should be able to hear the compressor Overtime the compressor will get noticeably louder. This doesn't necessarily mean that it's failing or should you be alarmed. If you are concerned I would suggest that you take it in and get it checked out.
start by checking a/c compressor.
why does my 1996 ford tarus wagon make noise when i turn key in ignition
Was the proper amount fo oil installed in the compressor and accumulator when they were replaced? That is the reason ,I, as a repair shop owner will NOT use a remanufactured compressor.
the a/c compressor cluth is bad. should make a grinding noise when not on and goes away when it is on.
The clutch assemble is shot...
If you want to remove the Ac compressor completly, you can pick up a bypass pully and bracket at Murray's or Pepboys for around 25 bucks. It just bolts implace of the compressor and reuses the stock belt. You might have a worn bearing on the compressor shaft which could cause the grinding noise. Make sure that it's the AC compressor that is grinding, they can be quite costly. Hope this helps.
Without the year, make or model of your vehicle it could be a bad compressor and or a bad compressor clutch.............
Maybe a bearing in the compressor
Definately. Have it looked at by a professional.
is the humming coming from the front end of the vehicle? i have a 1996 explorer with the same issue. yes the noise come from the front but not all the time seems to make the humming noise when it gets hot
Probably, sense Toyota's sound loud and like vacuums anyway...
To prevent icing up, the AC compressor only turns on when the "low side" pressure is above a certain set-point. Once enough refrigerant has been pumped out of the low side, the compressor shuts off momentarily. When it comes back on it may make some "random noise".
Where is the noise coming from? If its from the fenders or wheels is a much different problem than if its coming from the transaxle.
Inspect the steering components, suspension, and brakes.
The compressor, along with several other parts make up the ac system. The most common part to go bad and need replacing is the compressor.
Make sure its the ac compressor making noise. The idler pulley and belt tensioner can make alot of noise, also. If you haven't replaced those, I'd start with that as it's a fairly inexpensive fix. If the noise doesn't go away, no harm done because those components should be changed every so often anyway. (belt tensioners lose spring tension over time). If you're sure it's the ac comp., the compressor bearings are probably going bad and you'll need a new one. I have a '99 Jimmy and the comp. started leaking oil from the front seal a few months ago. Still blows could air, but recently started making noise. I'll be replacing it real soon.
Most of the time around 90 percent this will mean that the a/c compressor is bad internally.........
check the override switch and make sure that it did not get switched off if it is on you will more than likely need to replace the compressor
