So, my blower motor suddenly stopped working. I know it was working fine before I installed my new stereo. I went to put the heat on tonight and no go. Im not sure if I used the blower since I changed the stereo. I guess its possible that I knocked off a connector on the heater controls. Ive heard about some relay under the glove box that people have hit to get the blower working again. Does the 2007 have that there too? I also hear a hissing sound inside the dash that eventually subsides after about 5 seconds after I shut down the motor. Possibly related? Its just the regular heating system if that helps. I can here the doors and actuators working when I switch heating modes. Just no blower.
