Anyone ever have a noise from the HVAC blower fan?
I have a cricket chirp like noise coming from just above the passengers feet under the dash. Goes away when I turn the HVAC system off, and I believe its the blower motor. It even goes away from hitting the brakes or accelerating a lil harder. I'm hoping I can pull it apart and adjust it a lil somehow and make it stop. Just wondering if anyone has dealt with this area at all and if I should know anything before jumping in.

Hi BBSS,
I tried the lubrication thing, but that didn't last long
.
I ended up replacing the Behr blower fan assembly during normal maintenance. It cost me around 330 euros, including work. I can say it was really worth it!
Kind regards,
Vigoras

Mine chirps like crazy. Drives me nuts. I use the heat full blast until I'm about to sweat to death and cut it off until I'm about to freeze to death. I can't wait for the summer when I can roll down the windows

Mine was chirping from rust on the shaft of the fan. I took it out, sanded off the rust, oiled it and put it back. It's been good for a year so far.
I followed the instructions in the link above.
