Hey guys,

replaced the battery in the G37s this morning. It was sounding really weak over the past week and figured it was a god idea to do so. Easy enough install and removal. After that car started up as normal but the windows when I opened the fort rolled all the way down instead of the usual 2”. Then they would not roll back up unless I was in the car to do so. ( this isssue has been fixed that’s to this website. ) after that I stoped the car and went to check it again. Nothing. 1 single click, and nothing. Fuses have been checked. None blown. Then I was researching and read about the steering wheel lock being a culprit sometimes. Took the dash apart and used my ratchet to tap against it while trying to start. This time it gave me a weak turn and a half. Have tried that again but have never gotten the same result. Don’t know what happened but any help would be appreciated?

 

I assume you've verified the connections on the battery?

 

A failing starter will cause a slow crank, and eventually lead to a click like you’re having, most likely your starter was overdrawing and you mistakenly thought it was a failed battery. If it only clicks, try tapping it with a hammer and see if it starts working, if so you likely have a bad starter.
