Hi all. Have some strange electrical issues in our 2007 Sonata. The alternator failed while driving on a highway and we needed it towed to get that and the battery replaced. Everything seemed to work for a few days, but then we noticed the windows sometimes wouldn't go up or down and then worked again for a few days. Then a few days later we noticed that MANY electrical things went all of the same day. None of the four windows went up or down, the blower had the ability to STAY ON even if the ignition was off and the keys out of the car, the rear defroster no longer worked, the headlights did not come on in auto mode any longer, the seatbelt off and lights on reminder sound wasn't working. All of this stayed "broken" for about three weeks. Then all of a sudden one day EVERYTHING started working again and stayed that way for about two weeks. Now today I got in the car and all the same things aren't working again. I first though either the alternator going OR the alternator/battery job fried something for good. Then when it ALL came back I thought maybe the computer had to reset or something. Now with it out again I'm thinking maybe something loose somewhere? Has anyone heard of something similar to this? THANKS!
