    The other day of when I was coming home from work the AC went out and started blowing hot air. The following morning I started up my car and noticed there was a rattling coming from the engine compartment. Any idea what may be causing this noise or why no AC.

    Here is a video:

    Poor fuel can be the cause, too much water in the gas will cause this. Also these are known to do this on cold mornings or after a few days of sitting even on a hot day.
