Getting Car Ready For Winter

It has taken me longer than I wanted it to take, getting my car ready for winter. I was without heat and yesterday I got it in and they found out that it was simple - the switches were broke. Put in new switches and now I have heat. It is an older Focus which for some reason has some silly things that happen to it. Like the radio not working and then working, the lighter now working, the switches breaking for heat/ac, driver's side door breaking, etc. Any crazy thing you can think of it has happened in this car!
