Car Forum / Toyota / Toyota Cars / March 2007Corolla 2002 - noise on CD and radio
Hi, Few day ago while I was listening on Corolla standard factory radio I start to notice a noise that seems to change when I brake or accelerate. When I brake, is very low frequency and when I accelerate the frequency increase. When engine is running idle there is no noise. There was no work done on the car, nor on engine, nor electrical noise started while I was driving normal. Any ideas about how I can troubleshoot as I don't want to start buying another stereo and/or alternator useless? Had anyone similar problems? Can this be from the radio/cd ? Thank you, Chris > Hi, > [quoted text clipped - 14 lines] > > Chris How many miles? I am guessing the noise is like a whine. A whine usually is caused by the alternator, and usually means there is a bigger current draw. How much stuff did you have running? Heater, headlights, rear window defroster, etc, etc...having all this stuff on can cause a current draw, esp with a battery on the way out or an alternator needing some maintenance. Although, it may be time for plug wires, but this is usually indicated by more of a snapping sound. > Hi, > [quoted text clipped - 15 lines] > > Chris Factory radio? Hi, The car have 71K miles and the sound is more like snapping when I brake. The snapping frequency seems to increase while I accelerate. It is a standard radio.

To clarify, that is spark plug wires, not wires for the radio.  SignatureRay O (correct punctuation to reply) Has your AM reception changed or vanished? That's a sign of a bad antenna or antenna wire. > Hi, > [quoted text clipped - 29 lines] > > Factory radio? Yes factory radio and CD. After like 7-8 of annoying days in which I kind of renounced to use the radio and CD because of the noise, the noise went away without any intervention :-). Did not changed any spark plugs or wires or anything.

Engine block to battery ground strap, or hood ground strap, or the ground lead on the antenna... --<< Bruce >>-- >>>"Zorba" <nospam@nonexistent> wrote : > [quoted text clipped - 19 lines] > > --<< Bruce >>-- In my experience....cured by itself....isn't a forever thing....LOL SignatureScott in Florida |
