I need to know where the fuse is for the heater and if there is a relay for the heater. My heater just stopped working and don't know why. there was nothing wrong with it, it was working just fine.

Did your heater blower motor stop working?

If so check fuse in fuse box inside car. If fuse is OK, then posible blower motor resistor, or BM switch.
