knocking noise when car is started
Yesterday when I started my 01 CL type-s it made this strange knocking noise which sounded like it was coming from under the glove box. After a couple of minutes the knocking stops. I have heard it a few times while driving and seems to be happening more often. I have no check eng lights or codes. It doesn't sound like an engine knocking but more like an emissions problem. Any Ideas?

this AM I started car and turned on defroster. soon as the windshield was clear I turned it back to auto air and then I heard the popping noise. So I repeated the above and got it to pop again. Any Ideas?

Possible air in your radiator? Im reaching here, but it's possible if there's air in your system if could pop as it goes through.

No that has nothing to do with it.
Maybe your blend door, or something with the climate system. You should take the glove box out & inspect the system. Take out your cabin filters & check those replace if needed. There's a DIY for that with pics & details in the FAQ.
