Gauges, door locks, radio go crazy.weird noise from dash. battery tests at little over 12 volts. HELP

bad wring in the doors
and happens,
find the door that is bad and remove cards and see the damage.
to wires.

doors work ,key off. and if true, can short and drain any battery.
for emergency exit.
door switches bad. dome too switch, windows too and locks.
all that must be checked for good and bad
any shop can fix this, electrics,+ auto.

Hello Al,

Does your dash display a flashing "service soon" indicator?
Have you checked for fault codes?

You have a good battery, your ignition switch is powering up the vehicles dash board and the vehicle will start and operate normally....?

Any lights on the radio display?
Check for 12 volts on the radio power lead...no power? check for 12 volts across the accessory / radio position in the fuse box. No power but fuse is good...wiring issue in the harness.

Power across fused circuit no power to radio check radio's in line fuse...fuse good? ... radio bad or disconnected speaker wires.

Make sure all your vehicles grounding positions are clean and tight.

When you say your door locks don't work are your talking about the switch on the door or the remote fob?

Check your owners manual to check for any radio reset info.

Your battery is very low, enough to light the dash but not to start the engine. Get your self a volt meter that plugs into the cigarette lighter (any good auto store have them). You can now see the voltage of your battery. If it is less than 10 volts, then it will need to be charged/jump started. If the battery is good with 12 volts, then check the ground cable for a good contact to frame and check that the cables are secure on the battery.

suspect ignition switch., check fuses & relays.

It sounds like an alternator related issue. Once the battery drops below 12 volts it will do lots of silly things with gauges and thats why when you change it all works fine. Check that with engine running with a volt meter you have 13.8 to 14.2 volts across the battery, if not you may have an alternator issue

sounds like your battery is dying,, have it LOAD tested,, it could show 12 volts, but the amperage isn't up to par,, even with one bad cell the battery will drain , also,, once you know its fully charged, start the vehicle,, use a meter at the battery posts to check the voltage,, you should get a reading of 13.5-14.5 volts, if not your alternator isn't doing its job, make sure all battery connections are clean and tight.

SOUND LIKE DEAD BATTERY OR LOOSE OR CORRODED BATTERY CABLES.HAVE BATTERY TESTED USING A DIGITAL VOLT METER.BATTERY VOLTAGE SHOULD BE 12.5 VOLTS IF NOT HAVE BATTERY CHECKED AND CHARGED.IF BATTERY WAS NO GOOD.HAVE ALTERNATOR CHECKED OUT.TO MAKE SURE IT IS CHARGING BATTERY.TO KEEP FROM LOCKING OUT YOUR RADIO.TURN IT OFF BEFORE DISCONNECTING BATTERY CABLES.

Electric Testing Techniques You Need to Know
There are no magical fix's for automotive electrical problems , testing for B+ voltage an good grounds .

sometimes when the battery is too low the gages will go haywire.check you battery terminals for good conductivity and current levels. sounds like a low current problem.computer runs on 12 volts not 11 or 10. low current will give poor performance and bad electrical response.
try that first then look for shorts under the dash ie naked wires or burnt wires.
good luck.
