Changed my cabin air filter today, it was dirty, had some pine needles and such on top of it. Anyway, no issues, installed new one put it all back together. Started the ac and there is a new noise coming from the blower motor, you can hear spin down as the motor does. Took it all back apart and removed the filter and same noise. Thinking I dropped a darn pine needle or leaf down there, of course cant get anything down there to see. Just wanted to see if anybody else had any thoughts? Thanks in advance.
