A couple of weeks ago the lighting system went into night mode (headlights come on, radio/AC lights dim, gear selector display in cluster dims) in the middle of a bright and sunny day. 5 minutes later they shut off.

It has been working PROPERLY, intermittently since then. It'll stay in day mode for about 2 minutes after I start the car and then go into night mode. It mainly stays in night mode all the time now, regardless if it'* day or not.

I take it that my photocell in the middle of the dash is dying or something. Has anyone ever had any troubles with this little guy before?
