I am open to any suggestions to resolve this.
The most annoying problem i am finding now is the bloody radio! Current config is xm/Onstar/Bose 6 disc indash premium system.
Buzzing coming at any volume when radio is off all is good until the warning buzzer activates (seat belts/Brake/onstar phone ETC)
if i politely SLAM the passenger rear door it seems to go away, i have inspected all wires in the door, pulled rear speaker and checked connections, pulled up the sill plate and checked for pinched wires there, nadda, have looked under the rear seat nothing. when speakers are buzzing seems to be coming from right rear seat speaker. but also seems like right channel drops out completely.
I have read somewhere that the AMP in the 2005/2006 is located on passenger side behind seat in cover under rear glass?? other post say under the center console. anyone confirm its real location. i have also seen some post showing that the factory had bare bleed wires on the harness that may contact another lead? I do have rear audio controls and verified the plug connections and they appear to be fine, i can use headphones in either port and nothing changes. (have digital connections not the manual settings) I thing the amp connections may be the issue but was hoping others have had better success solving this issue. Also when system starts buzzing i get what also appears to be an alternator WHINE. the strange parts is that hitting the brake will cause an auditory pop in it as well. or any momentary electrical surge (turn signal,door lock, power window etc...)
To add to this note. - when you turn off the truck and then restart it appears to go away, sometimes it will return sometimes not. - Also noticed if i have a passenger in the rear seat it happens more frequently (again checked for bad wires nothing-why i think the amp may be there)
