2003 Toyota Avalon Q&A
2003 Toyota Avalon Question: lights flickering
what are the possible causes of lights flickering on my vehicle. the interior lights and headlights pulsate when i first start the car and then gradually stops. all electrical components and systems operate fine but the power seats make a clicking sound when functioned. battery is charging and in fair condition. any suggestions? - AAJAY
The battery has been charged and tested under load (using a high rate discharge tester and battery hydrometer)? Ensure the battery connections are clean secure and tight. Put a volt meter across the battery at rest it should read 12.6 volts, get a friend to start the car, the voltmeter should instantly read approximately 14.6 volts. I suspect the alternator may be failing. Does the battery light come on brightly when the ignition key is turned on and go out immediately when the engine starts. - patrick mannion
A weak battery will cause the flicker. Mine did the same thing until I replaced the battery. That was at the 6+ year mark. Not bad for an original battery. - Visitor
Had alternator rebuilt and put back in but light went back on and dash lights flicker. Is there something else I can check that may cause the problem?
V6, Charge of battery at rest: 12.6V, after car starts: 13.75V, new battery, I suspect the connection cable connections to the battery are bad.
A COUPLE OF DAYS AGO MY LIGHTS ON MY DASH WOULD FLICKER NOW WHEN YOU START THE CAR IT UNLOCKS THE DOOR SAMETHING WHEN YOU SHUT OFF CAR ANY IDEAS ?
