Pontiac Repair: factory radio amp, 2005 buick terraza, pontiac montana sv6

Question
where is it located in my 2005 montana sv6 we have looked in the dash and under the fold down seat. We thought it was the radio but it fine I can't get no sound for the radio or the dvd player.

Answer
Hi Angela:

Is this an SV6 montana "new style" or an old style Montana?

If it's an SV6 there is issues with the radio internally that cause this to happen. You may want to look in the owners manual and locate the fuse for the radio and remove the fuse for a minute while the key is in the on position and then turn the key off and they re intall the fuse and try that is not the radio is more than likly the culprit.
