Knocking/Pinging Sound --> Very Concerning
Hey guys, want to get your opinions on this.
When I started my car this morning (garaged every night) my defroster and AC light started blinking. No air was coming out no matter what setting it was at. I tried auto and manual where I control the strength of the AC, nothing, no air. This is actually the second time that this occurred. First when I bought the car and the second time being now. Usually it went away after I left the car off for a few hours or so. I started driving to work and I realized there was this knocking sound somewhere. I originally thought they were doing construction next to me and that it might be the sound of a hammer but when I turned around, there was nothing. I ended up pulling into a neighborhood to see what was going in. The sound was def coming from my car. It was like the sound of a raindrop hitting a hollow roof. I got out my car and noticed that the sound could even be heard outside. It was loudest about 1 foot left of my gas tank. Could this sound be my ac/defroster acting up or something more serious?

Oddly enough, the sound went away right now when i went to go start my car. The AC is working fine again too.
Good thing I have this on camera. Not sure what to do in this situation, whether I should still go to the dealership. |

If the ac isn't working, it could be a failed compressor. Problem is that that is on the left side of the engine. There's nothing mechanical near the fuel tank that would make that noise AFAIK.
I would have it flat-bedded to the dealer, as it sounds serious and possibly engine-related. |
