I have a problem with my Opel Corsa D 2014: when I turn the air conditioning , I hear a noise. Even if i don’t turn the ac on and just run the fan i hear a noise . I thought it was the interior blower motor and so I changed it but that didn’t solve the problem. I also changed the cabin air filter but it also didn’t solve the problem.
I have also looked into the air duck with an inspection camera to look if something fell into the air ductand but i didn’t find anything.
- A video so you can hear the noise
