Fuse is good defrost lines are good
There should be 2 wires connected to the defrost element. You will need a meter which measures 12 volt DC. When you turn on the defrost, it should measure 12 volts DC across these 2 wires. If there is no voltage, you have a power supply fault. Broken wire of switch. If voltage is there, then there will be a break in the defrost element. These can be repaired. There is a special type of glue / repair kit that can be purchased from most Auto part stores.

you need to make sure the wires are on the glass on each side and there is no broken wires in the glass there is a repair kit at a auto store to fix if you have a volt meter test it and that way you can find the problem look for breaks in the wire in the glass and do not for get the wires on each side of the glass.
