Hey guys this is my first thread here. I have a 99 Nissan Maxima. Over the past 2 months I have had the radio shut off along with the time clock in my Maxima while driving. It shut off for a few minutes then came back on and worked fine. This has only happened maybe 3 times over the past 2 months. When It comes back on I can hear a "click" from under that dash. The click sounds like a relay. Then this morning I start my car and the damn security light stayed on for some reason. It's never did that before. Any ideas would be appreciated guys.
