While I was out this afternoon, I turned on my A/C and a few seconds later, this loud knocking noise was coming from the passenger side dash. I turned it off and the noise stopped. When I turned it back on it started, so I went through all the modes and when I cam back to the dash vents it stopped and has been working fine since. Has anyone experienced this? If so what was going on?,lol. Thanks.

 

probably a blower motor....as long as its blowing strong you are good to go.

 

Oh ok, I see. Yea, the air was coming out fine, it was just the noise it was making. Thanks for the info
