I have a 2009 avalanche ltz. The 3rd brake light is not working I took it out and the led's are all good when I comnnected a 9v battery to the leads. Rest of my lights work fine. What the heck?


Did you check the fuses? It could also be a bad connection somewhere in the cab.
If you have had anything like extra speakers, sound system or alarm installed, suspect everything the installers came near.

2011 chevrolet tahoe security lockout... how do I reset it?


CAR ALARM ISSUES


It can be any of the car doors not got properly locked or the door is locked but the switch is not sensing the door locked. Open and close each door again properly.

Or else its problem with any of switch wiring getting in contact with alarm wiring causing it to happen.

And last thing alarm connections need to be inspected. It's getting short somewhere in between.


There are few help links with solutions, to troubleshoot these types of problems. I suggest going through these links.

Factory security system intermittently going off. Wondering if it is a bad sensor or switch. Does the door LED flash a code? 8 long flashes followed with normal short flashes.

2007 hhr. Battery was drained. Mother left lights on overnight. Tried jump starting no good. Tried charging with new charger nothing. Did notice that once you put the key in the car the alarm lock light...


your alarm system has been tripped when the battery went dead, to get the information on how to reset the alarm is to call the car manufacture to get the procedure, and should not cost you anything.

Avalanche alarm goes off and key wont start


Try disconnecting the battery cable for a few minutes. This may clear the security code and allow the normal key to operate. The sensor in your tire may have gotten damaged when it was repaired (this is not uncommon). The solution, take it to a tire store, they can change the sensor if needed.

Take the SUV to an autoparts store that features free charging diagnostic tests. They will determine if the alternator is putting out sufficient power to recharge your battery. There's also a very good chance your battery is dead. It's not uncommon for a battery to need replacing (especially in a truck with all the bells and whistles I'm sure the Santa Fe has) after 4-5 years. It's also important to ensure there's no corrosion around the battery posts/cables (will have a white or green powdery appearance). Corrosion would prevent the battery from accepting a full charge.

I hope this clarifies your problem. It's unlikely the alarm system is the culprit provided it's not "going off" all day long. Best of luck and please feel free to post back with any other questions.

Mitsubishi Magna GLX 1993 jumpstarting sets off alarm!


Is the alarm factory fitted, cheap, or a top of the range.
the factory alarm you can pull the cable of the horn untill you get the car started.
there are some alarms that go off when there is a voltage change, and some will keep going for a couple of minutes if the battery is dead flat untill there is power to equilze the power abit,
and some alarms have a key over ride in the siren.
if its a cheap alarm take the battery of and charge it,(the alarm will cut out as soon as the battery is disconnected.
~dont jump start from a dead flat battery, as it can cause a lot more problems with the electrics, leave another car running with the jump leads on for at least 5 min first.~
