Sounds like the battery is a drain on it, check with an ammeter on the red or black wire to see how much. Shouldn't be over .2 A normally.

Also can try changing batteries, as when some batteries get old they do not hold a charge.

If you have the original battery, it's 5 years old.

Typically, batteries last 3 years on average.

Durango battery drain

Did Autozone check the alternator or the drive belt to see if belt was worn or loose? Did they put the machine on the vehicle to test the alternator? Did they look for a short in the vehicle wiring? Hope this Helps.

Uninstall Garage Door Opener

You do not have to remove the garage door opener. Just open it up and change the code inside so it no longer opens your own garage door. The owner's manual will tell you how to do it.

Two of my power stering hoses need to be replaced and it is not covered by my waarranty. Can I have a mechanic do this without creating a problem for my 2005 Sts cadillac

Super expensive labor costs to replace the high pressure power steering hose (in my car anyway) due to its location behind the engine. I started buying power steering fluid with "stop leak" and adding it every couple of days when my steering would become difficult and start groaning. I did this for a couple or three weeks. My auto repair man also added a conditioner of some kind and now, even though I still know that I need to replace the hose, I can save the dollars over the next few weeks and do it on my schedule. It's been over a month since my steering has given me any trouble at all. I hope this helps you.

I just bought a used 2000 cadi had a crack on the radiator and was leaking major i ordered a new radiator..but in the mean time i bought a sealant to seal the crack temp and it...

put the new radiator in the car,forget about the sealant,that is for a temporary fix. You can buy sealants that can fix some head gaskets without taking the engine apart,you just have to follow the directions that come with the sealer to do it right the first time.make sure you refill with quality antifreeze after you get done.

I parked the 2005 STS for few months. It won't start now even with a jumping cable. What can I do to fix the battery that has drained ?

charge the battery with a charger. newer vehicles with security systems will drain batteries when the vehicle has not been used for extended periods of time especially in cold weather.

1999 cad concourse, 75,000 miles, excellent shape. have had 3 or 4 times over past 6 months: engine wont turn over. (like a dead battery but put in new one last year). dash lights, horn,security,door...

This car might not get enough exercise. By that I mean there are things that are running all the time, remote entry systems, clocks, alarm systems. You may have a new battery, but it needs to be kept up to snuff. Sitting alone in the garage with NOTHING running, the battery will lose about 1% per month in ideal circumstances. As I said, your battery is powering all kinds of things while sitting in the garage so the drain is more than the 1% I mentioned. You may want to consider a trickle charger on this car if you are not able to drive it for at least 20 miles or more per week every week.

It seems your average mileage is just under 150 per week. I'm guessing you don't drive this car much on short trips, rather the bulk of your miles were highway on trips.

If I missed the boat on this question, please add a comment and I will try again.

Thanks for your question at

When I turn the key on my car the radio and inside lights come on

I had the same problem for about five months, sometimes the car started for two months than all of a sudden it make take anywhere from 10 minutes to an hour to get it to turn over. Final analysis (when it finally would not start for two days) a new starter was needed. (2001 Cadillac STS)
