Hi I have the same problem except my T/L CTSY fuse melted in the fuse block. I was thinking of running a separate line through the firewall with a 20 amp inline fuse holder.
my T/L CTSY fuse melted in the fuse block.
That's exactly what fuses are designed to do.
Seriously, I'm sure you mean that the plastic casing (i.e. the colorful part that houses the fusible strip and associated stabs) somehow got wicked hot. So hot, that it "became as one" with the surrounding area of the fuse block. That should not ever happen.
There is either:
1. Something really wrong with your fuse block, or
2. You were sold a defective fuse (which BTW, would be the basis for a very lucrative lawsuit), or
3. Your are not being totally forthcoming with the facts. Look up the word "disingenuous". Never mind, here is the definition:
not candid or sincere, typically by pretending that one knows less about something than one really does.
Can't you take something... like a little screwdriver and pick it out. Even if it comes out in a less than delicate manner - and the area around the slot looks bad when you're done - it doesn't matter. The
front face of a fuse block's molded plastic case only serves to provide access to those copper clips (sometimes referred to as tulips) that the fuse stabs into. Also it is for printing the name of the circuit(s) the fuse protects.
As a rule, those female clips are set far back from the front face of the block that accidental contact with them is not possible - or at least very difficult. All the real work goes on in the back of the block. That is where the clips are securely held in their assigned places and the associated wiring is connected to them.
First of all, you have to see what you are dealing with. Just do it - get the remnants of the fuse case out of the slot and inspect the clips. They will almost surely be able to still accept the fuse stabs. If they seem to have lost a bit of their clamping power, take the little screwdriver (the same one that you used to remove the melted fuse case) and bend them inward towards each other.
If however, you do decide to pick the melted fuse casing out of the block, and find that the clips are severely damaged (burnt/melted to the point where they are not serviceable or able to hold a fuse), you
have to find out what happened to cause that damage. Fuses hardly ever continue to allow that much current flow - to the point where they get so hot that they melt. Something happened with wiring behind the fuse block - not in the load side.
Good luck - and come back tell us what you are planning. Some of these guys are nice, and they'll help you figure out how to do a proper and safe repair.
