When I turn on the ac unit, I sometimes get a low pitched squeaky or cliking noise. It will come and go at times and sometimes it comes when turning the steering wheel. Anyone have any ideas? Also, when I first strat the car in the morning the air bag light comes on and stays on until the car warms up ( about 10 minutes). Any ideas?

Thanks,

I have the same squeaky noise from the AC (I mostly hear it when its cold though, from the heating system, but it is when the temp system is on).. Don't have the airbag light issue though... I'd like to know what this squeak is about myself.
