Please help with rattling noise
 

Hello all,

I am trying to understand a noise that is coming from my 2000 honda civic. There is a rattling noise best described as one that is like touching the tip of a pen on the moving blades of a plastic desk fan when it is powered on. It is only intermittent and goes away on its own after a minute or so, or if I turn off the fan using the A/C knob. However the rattling increases as I accelerate and decreases when decelerating, so it is not a consistent volume. This is the best I can do to describe it without taking a recording, and any help on what to check would be appreciated. I plan to see if there is something in the blower fan, but I am not sure if that is even the problem.

Thanks :)

How's your oil level?
Does it make this sound while turning?
Does it ever make the noise when the fans are off?

Thanks for the replies.
I just had a complete fluid replacement , oil change and other preventative maintenance done about a month ago. Today during driving, I have now ruled out the fan as being the problem, because there is no sound when the fan is on without the A/C being on. When I press the A/C button to turn it on, the sound starts for a few moments before going away, or until I turn off the fan. What could be the broken part? Also there is no sound when the fans are off. Thanks.

Well I took it to the mechanic and it has been diagnosed as a broken compressor. I am debating whether to buy the parts and do it myself (although i have no experience) or take it to the shop for labor. Any recommendations for a good compressor? I am thinking of getting this one:

Are there ones manufactured by Honda (OEM)?

If you don't have experience with A/C or car work, then you are best off paying a professional.

In brief, the job entails:

• Recovering of the refrigerant
• Removing compressor
• Flushing system of debris generated by failed compressor
• Installing new compressor with new oil and receiver/dryer
• Placing the system under a deep vacuum
• Leak testing system
• Recharging with proper volume of oil and weight of refrigerant
