Strange sound coming from cabin air filter

There's a weird noise coming from behind my glove box so I think its the cabin air filter although I just had it replaced. If anyone knows what it is please let me know.

 

Like the sound of small animals angrily trying to get out?

 

debris in the blowmotor assembly, happens all the time when pulling out the old filter all the leaves and debris ontop the filter fall in. Reach your hand in n feel around

 

It could be your blower is going out like mine did. Toyota replaced it and I have not had any more problems.

Like some of the others said, just open it up and see for yourself and feel around. Whoever replaced it might not have gotten all the debris out cause a lot of stuff will accumulate there throughout time.
