I have a 2004 Dodge Ram 1500 4×4 off road. I am looking for a replacement seat for the driver side. The seat is currently electric and in rough repair. Do I need a total new seat or would I be able to get just the bottom part and then the backrest?

I have a 2004 Dodge Ram 1500 4×4 and speedometer lights, dome light, my turn signal interior lights and my accessory lights (a/c light, radio light, glove compartment light) went out. Everytime i put a new fuse in, it pops as soon as i put my headlights on.
