Hi All,
My 1999 5.3L Silverado has had this noise coming from the ventilation system for a few weeks. I ordered a new blower motor thinking this was the issue. After the install the noise is still there. I took my glove box out to listen for the sound and it only can be heard when my ventilation system is in the off position and the sound is coming from the passenger vent area. Any idea what this could be? When the heater or fan is on, the only thing I hear is the system, no vent popping or growling.
Thanks,
George
