Question -
I had this problem when I bought this car used and they said they fixed it but obviously not. It has been at least 9 months since this first happened and has not happened since. All the interior lights are staying on even when the car is off. Also the check engine light comes on and stays on and then it will go off. I do not have an owners manual for this car and have no idea which fuse it could be or where to look. Please help me as soon as possible or the next problem will be a dead battery. Thanks for your help!

Hello Tiffany
open the doors u will see a button spray with wd 40 this can cause the problem the fuses are under the dash uper left side good luck to u hun and u have a pretty name pete please rate my serivice pete

I looked and did not find a button on the door - the dash indicator shows that the driver door is ajar even when the door is tightly closed. This is happening all the time now along with the check engine light staying on. It seems like there is a problem with something in the electrical system. Sounds like I know what I am talking about but I need more help.I know where the fuses are if that could be the problem only you can't identify which one is which without an owners manual (which I do not have). If you can please help me again I would appreciate it. Thank you for your time.
