NO POWER
Stock stereo was replaced 2 years ago & the aftermarket one was working fine. For some reason in the winter it had power and all functions displayed but there was no sound/audio. Even though the illuminations on the display flashed to the music like it was still playing. A friend advised me that something was shot inside that powered the audio out. I tried 2 faceplates for this radio because someone I know has the same stereo. My faceplate worked on his, but his had the same “no sound/audio” in my car.
So I just bought another aftermarket stereo but the radio constant 12V from the Lexus wiring harness doesn’t seem to have power. Factory harness didn’t have power either after the no sound issue occurred. I can get power from the fuse panel with a spade tip wire to power the stereo, but this is not a constant 12V so the clock & pre-set radio stations will constantly need to be re-set. This would drive anyone nuts so you can see why I am looking for advice.
How/where can I get a constant 12V? Can’t go direct to the battery cause that will blow the stereo. Is there a way to steal power from the factory wiring harness (behind the radio & climate controls) for the factory CD changer that I am not using? Or is there a fuse in the panel left of the steering column by your left knee that has constant power?
Thank you for any advice.
Lane, first double check ALL your fuses and make sure ALL your fuses are good. You can do this by using an Automotive Fuse Tester
and making sure all of your fuses aren’t blown. If all of your fuses are good, run a wire to your steering column and use the white wire in the ignition switch harness. This will give you a constant power source for your radio. Hope this helps. Good luck with your 1996 Lexus ES300 radio installation.
