I have a 2010 Lacrosse. 2 days ago when I got home my camera was back . I still had the quide lines but no picture. It was dark out. The next day, when it was light the camera worked. When I went out later; when it was dark it did not work. Out of curosity I pulled into a lighted car was and it worked. This one has me stumped.

 

Is the lens clean?

 

Yes the lens is clean. It works in the daylight but not dark. I even went into a lighted car wash and it worked when I was under the lights.

 

Sounds like a problem with the camera sensitivity.
