Question about 2003 Chevrolet Avalanche

1 Answer

03 avalanche power keeps on drawing from somewhere and in the morning its dead. I will jump it and it will run fine!

I will turn the truck off and the battery light and the radio stays on. I popped the hood and hear a humming sound in the alt. So I unplugged that, took out an ignition fuse out so that everything will turn off on the dash including the radio and its still drawing power and if I let it sit there like that over night, I have to jump it the next morning!

    I added a new batter and alt. If it was the doors, the interior light would stay on and the battery light, PRND321 would not be on/with the interior lights off.

Are you leaving anything plugged in, cellphone charger, radar dector, emergency lights, cb, etc, if so unplug all of it that will kill the battery, if not the case, you got a short somewhere

SOURCE: CHEVY 1500 TRUCK HEADLIGHTS TURN OFF WHEN YOU TURN ON SWITCH

If you have replaced the switch, and it is still doing it it sounds like you definately have a short somewhere in your wiring. On the other hand if the dimmer is in the turn signal arm ( forward bright back dim ) the problem could also be there in the dimmer switch, such as a short being caused by that dimmer switch being faulty.Auto Zone and Discount Auto Parts both test a lot of your electrical problems for free, and/or may have some knowledge to more accurately pin point the problem. Not sure about Pep Boys or some of the other discount auto part chains.

SOURCE: battery keeps dying due to radio+clock staying on

your radio is staying on? you have a bad door switch.the bcm does not see door opening and thus does not turn radio off. most likely the drivers door.

What Systems draw power when the car is off?


Have to do a Parasitic Current Drain Test, to find
the circuit with the fault,then component test items
in that circuit

You have a module,relay or other item, not timing out
or going to sleep

You can have failed switches in the doors,failed alternator
diodes,many things that can cause that

Even the Evap System, which on some cars, run tests while
your sleeping, can be at fault

Check for OBD Codes in all Modules, with professional scan tool,
then do the drain test, leaving the doors closed

Hi Linda, I'm glad to help!
If I'm reading you message right, your cars battery is going dead and you must jump start it to get it to run. Here's the thing, a cars battery and alternator can be just fine. BUT, the system can still have a draw coming from somewhere that can draw all the power out of the battery and thats why you need to jump it. This can happen intermittantly as well making it almost impossible to find the draw. If this is whats happening then your mechanic will need the vehicle for awhile to find the draw. I'm not there so its hard for me to say this is whats going on, but it's a good place to start diagnosis. Hope this helps and have an awesome day Linda!

theres a draw somewhere. these are sometimes hard to pinpoint.start by checking that all lights turn off,glovebox underhood light all lights,you will need a meter to meter the draw amps, then with key off doors closed look at the draw amount,.02 to.03 is allowable, start removing fuses and watch if amps drop,one fuse at atime, start with this to try and pin down a location of the draw.hope this helps.

Hi, my 2002 Dodge Dakota has been going dead lately and needs to be jump started. I have already replaced the battery to no avail. It usually goes dead after sitting for a few days. But the max battery...


It could very well be a defective battery, you could have 1 or more bad cells in the battery. A voltage regulator or an alternator. If it isn't one of those then there is something drawing power from somewhere that is causing it to go dead.

Battery dead every morning


Something is shorting out (drawing power but not returning it to the battery)
Make sure you don't have any accessories plugged in and running or anything else running or on when you go to bed at night as this would draw down the power!
I'm assuming you have to jump start it every mourning.
Is that correct?
If so the new battery and alternator will be strained and go again soon!
Go to an auto parts store like Advanced Auto Parts and have your battery and alternator tested (they do this for free) and may be able to verify that you have a power draw somewhere!
A jury rig fix would be to put a battery disconnect (available at any auto parts store and pretty easy to install) at the terminal to the battery and disconnecting every night but that won't fix the power draw.
What was the original problem that led you to change the battery and alternator?
