Gremlin in my electronics

[Big Tex Phil]

I have what I think is a fairly odd problem. There is a gremlin, or fault in my computer system that affects different aspects of my car. One time, the windows forget the auto function, next time the right rear window will not roll down. Sometimes the radio will not play or the back up camera has a really fuzzy picture. The worst problem that happens, though is that the fan motor sometimes will not work for a week or more at a time. That is really bad in Texas Summers. Each issue will usually clear itself up, but it can be really irritating. Has anyone else experienced this and what did you do to fix it?
Thanks
Phil

I would start by monitoring electrical system voltage. Perhaps your alternator is getting ready to retire. I would also check for AC voltage superimposed on the DC voltage.
