Fuse Block Heater
I plugged my block heater in this morning, and it did'nt work, no sparking sound when I plugged in, and could'nt hear anything sizzling. Is there a fuse that could have blown, its a 95 f-350 dually, no operators manuel. Any ideas as to what could be wrong with it, I have juice to the plug in. Thanks

There is no fuse, it's just a heating element like what's in a water heater. If there is a short in the cord the end of your extension cord will get really hot. If the cord appears to be in good shape you probably need to replace the element.
Not being able to hear it does not neccessarily mean it isn't working, it takes at least a couple of hours for it to heat it up.

If you use your block heater a lot, and/or the end dangles in the breeze on the front of the truck, eventually the wires will break inside the cord right at the plug end. So check that before you go popping the heater element out of the block. New cords are reasonably cheap, or you can repair the existing one in some watertight fashion, or you could take this opportunity to drill a big hole in your bumper and install one of those cool receptacles with the flip up lid.
