Loud noise w/A-C and acceleration


#1

I have a 2004 Mazda 3. I just had it inspected and cabin air filter replaced. Now, my car makes a loud noise when the a/c is on and I’m accelerating. The noise sounds like a fan is vibrating /something is blocking it or like a motor is rev-ing that shouldn’t be. There definitely is something wrong that wasn’t there before the filter/s replaced. I watched a Youtube video on it… a real pain to replace them, but it looked like the fithad to be pretty tight… Could the filters have been installed incorrectly or some part not put back together correctly? I’m going to take it back to the shop…just like to be informed before I go…thanks

Could be, yes. Take it back, and have them check it. The noise is new, and if that’s the only thing that happened…
