Trouble with windows, heat, wipers etc. 9-3 Saab
 

Today I drove to work and everything worked fine on my car and then on my lunch break I noticed the windows wouldn’t roll down (none of them) and the the wipers wouldn’t work and the heat was off. Then I drove home and halfway there the heat blasted on and everything worked. But when I parked again and restarted my car later they were all dead again. This cycle happened about 2-3 times today. I’m worried because it’s very rainy and I need my wipers. I called my Saab dealership and he was very rude and said it’s probably a fuse??? Okay but I don’t know anything about that sort of thing. What could be wrong? I made an appt on Saturday but I’m scared to drive because of the rain and my wipers not working. Any thoughts?
