There's also a red 10-amp fuse plugged into the back of the radio.

If this fuse is bad will it affect the power antennae as well?

It's possible and likely. Depending on the specific radio model, when the 12 volt memory circuit is dead, some radios will be totally dead. Some will appear to tune and work but will only have no sound. Some models will work perfectly fine until you turn the ignition switch off and back on. Then the clock will go back to 10:00 or 12:00 and the station presets will go back to the factory defaults. If the radio is dead, so will be the things it operates. That is the power antenna and / or a remote amplifier.

Will I have to remove radio to replace fuse or is it possible to replace in place?

That 10-amp fuse is on the back of the radio next to the plug. You have to pull the radio to get to it.

Right after I put a DC/AC converter into a cigarette lighter, my radio and clock went dead (radio does not turn on), as well as other cigarett lighter adapter that was powering my GPS. No juice there.
I'm suspecting a fuse, but cant' figure out where it is, I looked in the fuse box under the hood but they are not labeled.

Thank you for your help.

? Model/Yr you probably burn the wire behind it or blew the fuse.

My car stereo froze up and would not let me change the station, am/fm, cd, or adjust the volume, yet it was still playing the radio station it froze on. After turning off the car the sound stopped but the LCD screen on the radio remained on even after removing the key.

We have disconnected the battery which shut off the radios LCD display and the reconnected the battery and restarted the car. No the radio will not come on at all. We have checked all the fuses and they aren't blown. All of the surrounding things in the dash work. Like the cigarette lighters but the stereo will not turn on.

I am completely confused as to why it would work and then now not work. Maybe the stereo is just shot. I am just wondering if there are any other possibilities that could cause this.

Thanks

Sorry, no other possibility. The radio has internal faults. Just replace it with an aftermarket unit.

The radio does not come on at all. I checked both fuse boxes and all look good. I read on here that there is suppose to be a 10 amp fuse on back of radio, next to power plug, so I pulled the radio only to find no fuse anywhere. Please help. Thank you.

Hello,

It sounds like the head unit is no good, but to be sure let's check for power and the unit grounds. Here is a guide and the wiring diagrams so you can see how the system works:

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Cheers, Ken

Thank you very much for taking the time to help me. Yes, the head unit was bad. I ended up finding another 1999 4-runner radio at nearby salvage yard, replaced mine and everything is working great again.

While driving the radio stopped working. I can not find the fuse so I am unable to tell if the radio is getting power. I am not sure if the radio is bad or I have a blown fuse. I have checked both fuse boxes and all fuses are good but none state they are for the radio. All other system work, just the radio is not working. Can you tell me where the fuse is and how to check to see if there is elec power going to the radio.
