I have been having the oddest electrical problems ever. I don't know if it is cold relate since it has been ungodly cold for so long. It started that my cigarette lighter wouldn't give my phone charger enough juice to charge the phone until I drove between 30-60 minutes. The car wasn't starting well in the cold so I replaced the battery (didn't change a thing, didn't expect it to but I was hoping for an electrical miracle). I still had the problem. I then realized that the rear defrost and the mirror heaters also took the same amount of time to start working. I took it to Subaru and they told me nothing was wrong with it (probably because I had to drive 45 minutes to get there). A few weeks later I notice that my seat heater is giving me the same problem. Just the other day I noticed that the auto dim on the rear view mirror wasn't working. I took a wild guess and turned the seat heater off and the auto dim started working. Has anyone had any of these issues? I have worked on electronics for a long time and never have a seen an issue where the longer something was on the better it worked. Any suggestions or solutions would be welcome. I have tried having one thing at a time on and every combination of things on at the same time to see if one thing might be causing the other issues, not so much.
