Most likely the compressor. It could also be the valve in the system too, when refrigerant gets low. What sort of noise is it???
Running too lean.
A leaking manifold seal on the intake will cause a popping noise on the 1996 Honda Accord. This can heard most clearly on days when the weather is cold because the seals tend to shrink.
If that's the extent of the complaint, check the serpentine belt and tensioner.
If the Honda Accord makes a groaning noise when reversing the can be caused by bad hub bearings. Hub bearings are what allow the car's wheels to spin, if gone bad they can cause wheels to come fully off the vehicle.
Power Steering pump my have a leak...
What would cause a grinding noise after a tire is replaced and the brakes are not worn?
If it starts but doesn't stay running after you release the key from the start position, it means your ignition switch is bad. Not a huge expense.
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.
Though there are several possibilities, by far the most common reason for that is a loose or glazed belt in the engine compartment.
Sounds like you might have a Constant Velocity Joint (CV joint) going bad.
a firecracker
