Is the noise present only when the A/C is on, or with it off, and only the fan blower on.
Only with the A/C on. If I turn the A/C (compressor) off and leave the fan on, the sound goes away. It tracks the A/C 100%.Is the noise present only when the A/C is on, or with it off, and only the fan blower on.
I have this too when I go around turns fast.I have a similar rattle. It didn't exist originally, but showed up after ~2 years. I figure something dropped into the nearly inaccessible area below the fuse box and rattles along the floor pan.
This sounds right. I was just working in the sill area and may have moved something around. Also, the sound is very uncentralized -- it could be emanating from the length of the sill.It is coming from the side of the car. There is a line that runs along the passenger side of the side sill that is now vibrating enough to hit the side sill. Take out your side scoop and put a piece of hose around the line and it should stop the noise.
