Question about 2003 Toyota Corolla
Need help solving electrical/audio problem.
LCD clock on dash worked only intermittently for about a week. (on and off at random every few hours it seemed)
Then yesterday, no sound from radio/cd/cassette player--only a pop from back speakers when system turned on. All is working/playing on system except for no sound. And clock below radio on dash is now not working at all. Everything else working, including both cig lighters/chargers,dome light, all dash stuff etc.
Checked fuses under dash and under hood. All good.
I might assume the radio amp failed, but that doesn't explain clock which is not part of radio.
I did use one of the cig chargers yesterday with engine off for phone charging, and then radio failed hours later. Not sure whether that is coincidence.
Maybe the amp and other radio functions are powered separately? and I have a short or in-line fuse issue in power to amp and clock? Not sure what to do from here other than open up dash and start tracing ...
Anyone have similar issue?
Hope someone can shed some light on possible solution.
Thanks in advance for any assistance.

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!

The radio, lighter and clock are controlled by 2 fuses:
The 15 Amp CIG and the 15 amp DOME, under the dash, driver side, for a USA car.

SOURCE: lighter stopped working,
The Cigarette lighter is run off of a 20A fuse located in the engine compartment just behind the battery. The fuse map will say P-Out and is in position #14. Hope that helps.

you probably didnt change the right fuse and had another one blown at the same time you also could have a primary fuse under the hood that blew. once fixed dont use pump again. not same amps drawn
