Car: 2003 Infiniti G35 Sedan

Post

I have a 2003 Infiniti G35 Sedan. For the past few months I have been having what I think to be an electrical problem.

While the car is running... The lights on the speedometer cluster will go dark, the AC will stop running, and the radio will turn off. However the engine stays running. In order for me to get everything working again I will have to turn the engine off and restart the car. Also today I noticed that my car will no longer alarm with the remote. I'm not sure if that is related.

This usually happens when I'm stopped at a red light, although it has happened when the car was jarred from going over a pothole. It has happened with regular driving. I'm scared that it may happen at night when I'm on the freeway and cause the headlights to go out.

Has anyone had this problem and what can I do? I'm hearing from the mechanic that it may be hard to diagnose and that it would basically need to happen while they are testing the car. Any help would be great appreciated.

I would start with the connections on the battery. Is there any corrosion?
Carefully inspect the battery ground cable especially where it attaches to the vehicle frame.
Your trouble description sounds like a poor ground connection.
Your vehicle is over eleven years old so a poor electrical connection somewhere could cause your problem.
Difficult to locate and may require lots of time if paying by the hour.

Good luck

2003's are known to have a bad circuit board which will take out the radio and A/C plus lights. Places like http://www.shortcircuitrepair.com/ can fix it.
