I just finished installing my homelink auto dimming mirror. It took me about 2 hrs to install. Auto dimming and compass and temperature reading is working, but the homelink is DEAD!!! I push any of the 3 buttons and I don't get anything!!! I think it's a bad unit but not sure. Can anyone Please give me any suggestions on troubleshooting this or just try to send it back?

 

Found the problem !!! It was and open in the wire !
