I have checked the fuses, the cables on the radio (is the original one)

Please help!! 🙏

From time to time it starts to sound but as soon as I turn the hummer off and back on it does not work anymore


Hummer H3 2006

 

Got an amp fuse #38?

 

Yes

 

Did you check fuse/25amp?

 

Yes, it was working. I still put a new one when I was verifying the fuses that had to do with the radio.

 

Check the amp/connectors/wiring. Look here:

 

Are your speakers dead? The OEM speakers suck and get trashed in the doors from weather exposure. Might be time for a long overdue upgrade.

Happened to me with my 07, and many others. First one goes, then another & you still may not notice until it is like 2 on the same side, or both in the front etc...

 

My 07 system is still oem. I drive above the speed limit with max volume. ALL speakers/sub/amp still working properly. All interior/exterior panels still vibrate with radio on max. Enough sound for me and the neighbors.

 

Most likely all of your speakers are toast. Take off a door panel and test the speakers with a 9V battery to the terminals.
If it does not "burp" it's dead.

 

Highly doubtful ALL 7 speakers failed. Radio signal is sent to the amp that feeds the speakers.
