I put an aftermarket stereo in my 1998 Toyota Avalon. When the car is off (key is out of ignition) the radio turns on ,but no sound. When the car is on, the radio turns off and no sound. I checked fuses and the fuse (15 A) under the hood corresponding to Radio 1 was blown and I replaced it. The aftermarket stereo ,I put in, is made by Sony. I checked if the car has an anti-theft stereo system and this car (according to Toyota) doesn't have one. I think I am missing something...? What do I do?

Hi there!

If you have checked all the fuses under the dash, Make sure you look at those closest the battery near the engine.

If these test fine, There is probably a cable fault.

If you have a meter, take out the 15A fuse for the lighter, and use a probe between the contacts and ground (steelwork/ Negative)

You should get 12V or thereabouts. If you don't - check engine bay area fuses in the same manner one by one, then replace after testing.

Pull the fuses relating to the radio in the same manner, one by one.

You should be able to identify the fault this way if you are methodical about it.

Hope this resolvesthe problem for you. If it does, Please take a moment to rate as Fixya!

Thanks.

I just had this same problem with a '96 . do you have a vats key in your '94? you need to bypass the VATS system. read some of the blogs on this site and it will tell you how to do it. I fixed mine with a $2 resistor from radio shack.

The second fuse panel that you seek is under the dashboard, on the driver side (for a US car). This box is called the "JB1" (junction block #1), and contains several relays in addition to the 15 amp "CIG" fuse that you need to replace.
Hope this helps, and thanks for choosing FixYa!
Happy Thanksgiving!

In my case the solution was a fuse on the passenger side inside fuse box. It is not listed as a fuse for the radio but it is none the less. If your cigarette lighter isn't working either its the fuse. On my 2004 it was fuse # 9 a 15A fuse.

Disconnect your negative battery cable for about 10min. After you re-connect, the stereo should reset itself and start functioning. Best of luck!
