Body & Interior
why is 03' 3.5v6 altima SE interior/headlights and brakelights flashing when car is running?
the alternator is putting out 14.2 volts.
Several possibilities; poor / loose / corroded ground connection - either at the battery or at the chassis ground connection. Check this first - should be clean and tight. Next, check the positive battery connection - same; should be clean and tight. Then, check the fuses and relay panel - look for any loose connections, clean any evidence of corrosion - sometimes the fuses can build up a slight corrosion on the electrical contact surfaces. Simply, unplug and reinsert - in most cases this will clean them.
