Hi, I am not very mechanically inclined. I however am inclined to keep $$ in my pocket. I just washed my 2009 Jk for the first time in the two years I've had it, and now the heater fan stopped. When driving heat comes out of the vents. When I'm not moving the heat does't come in. The fan doesn't work on any speed. Maybe it's a fuse. Problem is I can't figure out what number fuse I should check. If it isn't the fuse, what else could it be?
