wife says birds chirping in the passenger dash

[dpvon]

strange noises coming from passenger dash of my 2003 Maxima SE. Wife thinks there's birds in there. I think not. noise only present when heat/ac is powered on. sounds like rattle/chirp or perhaps some water sounds. any ideas and how to fix?

Does it do it with the AC and the Heater on or just the heater on?

Welcome to NICO.

It sounds like it could be the blower motor making noise.

This sounds like leaves (or leave like) in the a/c blower motor housing. I seen this happen a lot. Take the motor out and see what stuff comes out. If nothing is there replace the motor.
