Radio fuse blown - 2005 GMC Sierra

The radio fuse is in the fuse compartment located on the passenger side of the console. Remove the cover on the console and then remove the fuse box cover, search out the radio fuse and inspect to see if it has blown.

Wrong amp fuse or maybe you have a loose wire or a short somewherecausing the fuse to burn out?

Yes and fuses are tricky some don't look blown and they r, and some look blown and r not But to check the radio itself put a volt meter to the wiring connection on back of unit

Blown fuse(fuses painel box).Blown hidden fuse (on the radio wiring,behind the radio)Bad grounded ground wire(s).

is the cigarette lighter working if so it may be the one on the radio its self. can blow the radio fuse and not the main fuse. radio fuse is less think it is 5amp as main fuse can be 15-20amp fuse.

Wich fuse for the radio system would you like to replace? There are 6 of them. Your integrated control panel (dash unit) is controlled by the rear electronic module. This is all part of the multiplexed computer network in your car. I would recommend BEGINNING diagnosis of your radio by scanning your computer network for fault codes, then go from there...

Even if there is a blown fuse, this is an indication that there is an electrical failure which must be diagnosed and repaired. Blown fuses do not cause electrical component failures. Electrical component failures cause blown fuses. Replacing a blown fuse without diagnosing and correcting the fault that made it blow will only result in another blown fuse.

Where's The Fuse?

try plugging the wires back and check your fuses

The radio uses a constant power to retain memory(stations,settings,ect.) and switched power to run on. It sounds like there is a problem with the constant power connection. You can first check the fuse box for any blown fuses and replace any that are found. Also look around the battery for any wires with an inline fuse that could be broken. Try looking under the dash near the radio for any inline fuse holders that could have a blown fuse. You might need to pull the radio and start tracing the constant 12v power wire. First verify that it does have power and if it does then the radio may have been damaged from a voltage spike when the new battery was installed. If the wire does not have power then you will need to start tracing the wire back to the source of the short. It sounds to me like a blown fuse somewhere....

there should be a 'legend' on fuse box cover identifying locations specific to your model.blown fuses are readily identified when removed & inspected. after market radios usually have an 'inline' fuse on the power supply wire as well.
