I have recently noted that when I start my car with my AC button on or off, I am getting a "CLunk noise". I hear it more often with the AC on. It feels like if there was someone under the car and hitting the engine with a rubber mallet.
Is this common when starting the engine on the CL-S or CL?

Has anybody experienced that noise that Iam describing?

Some what unusual for a new car with less than 2k miles on the clock.

Probably the AC clutch disengaging so less power is required to start the car.

01 CL-S San Marino Red/Black, K&N drop in, no nav, rear wing, otherwise stock thus far, has an appetite for Bavarian cars.

 

Could be the ac clutch or more likely the active engine mount adjusting. It seems to a normal sound- I hear it on a lot of the cars.

This started recently. I noticed it at the first couple of times the noise went away when i turned the ac on. But now it seems the noise goes away when it feels like it. Sometimes it even makes the noise while driving out of the blue. I put my hand behind the dash (around the radio area on the passenger side) and i feel something moving. It's clicking away with the ac blower i think. I felt a little metal bar and a plastic piece attached to it. I try holding the bar and it seems to stop for a bit. Any ideas?
