I was testing everything on my dash board and came to find out my hater doesnt work.

I checked the fuse block and the fuse was popped so i put a new one in and it popped right when i tried to turn it on.

Looked for a lose wire or wire that is grounding out some where, cant fine any at all. Looks to be in good shape.

Could be the heater controls? Where should I go from here?

 

what exactly does the fuse control, maybe the blower motor is bad?
