Speaker (radio, DVD and bluetooth) works internittenly when cold in morning.
I have 2007+ G35 S sedan. Recently my speaker started intermittently stop working (for radio, DVD and the bluetooth. Other people can hear me when on the bluetooth, but I can't hear anything from speaker. Always accompanied by a "chirp" of static and then speakers start to work, then no sound, then "chirp" and they work. Hitting bumps/potholes sometimes makes it work again - sometimes not. Worse when car is cold from overnight sit in carport, better/less issue when inside of car is warm from sitting in the sun. I'm thinking a loose connection - but have misplaced my repair manual and not sure where to start looking in/under the console/dash. Any suggestions for me on where to start checking?
