2004 GMC Yukon Radio no sound output intermittently

[LaOrange]

Hi All
I have a 2004 Yukon with AM--FM--XM --6 CD Radio also on-star, also has wheel controls
Recently the Radio has no sound output at times then it will come on and work fine. Some times it cuts in and out. Does not matter which band or CD player. All looks ok on display. Just no sound at times.
Thanks in advance for your thoughts and ideas to trouble stoute.

Hi All
Yesterday I drove the truck twenty or thirty miles and the radio never put out any sound.
Did not matter if I hit any bumps or different exterior temperatures. Also no difference weather
AM / FM or CD. My thoughts is I have an amp going bad more then a louse connection.
Any thought would be a big help.

it would help to know if it is BOSE or standard radio.

Hi All
I sorry it is a Bose system

 

[Mr. 960]

might be your amp that is on the fritz. Check the main connector behind the dash bezel (lower right of the HVAC controls) You may need to remove the little pocket or T/C switch. Also pull up the plastic cup holders on the console to access the other plugs. The amp is accessible, but you need to take most of the console apart to remove it.

Thanks for your thoughts I will take a look this weekend

Hello LaOrange: I have the same vehicle (Yukon 2004) same configuration as you said. AND started to have the same problem. No radio when you start the vehicle, only hissing sound... Leave it ON and it Radio comes ON abruptly on its own after driving 15-20 minutes. Then it works normally until you switch off the car!
Please help if you had fixed this problem
