    You can remove your spare tire and you will see your power antenna. unplug the power connector and cycle the key again. If you don't hear it then is your power antenna for sure.

    Have someone stand in the front of the car and cycle the key, see if they can hear the grinding noise in the front. If they do then is possible that it is the gear in the headlight motor. There is the 180 fix or you can replace the gear with the brass gear kit.

    crap i didnt pay attention to the camaro part. if you have a standart antenna then I cant think of any other motor back there. The only other think that i can think is noise from the rear end or your fuel pump making noise but I never heard of the pump making that kinda of noise except the whinning noise.
