    Blower fan fuse receptacle melted

    Hey, so I noticed that when using the a/c with the fan on, not only did it blow the fuse but melted the crap out of the fuse and the receptacle to the point where it bubbled the clear plastic cover. Now I know this didn't happen with just the blower fan on. So something is OBVIOUSLY wrong.. (grin)

    Could anyone shed some light on this matter?

    I believe replacing the fuse block is now in order. sigh...

    thanks.

    I just finished the same process about two months ago. I read a lot of posts and many blamed the issue to the owner having the wrong sized fuse which resulted in melting of the fuse block. Well after my experience and can say that while that may happen, it is more likely what I experienced:

    1. All wires downstream of the fuse were intact - no melted insulation which would be expected if the wrong fuse was used.
    2. No grounds in the wires
    3. I dissasembled the fuse box and relaized the damage was on the upstream side of the fuse. The upsteam connection for the fuse is a metal clip that is connected to what I would call the motherboard of the fuse holder. The other side (downstream) of fuse holder is what is connected to wiring that goes to the various components. It appears to have been a high resistance connection between the clip and the motherboard - likely the connection became loose due to vibration, or whatever, so as curent flowed it caused high temperatures that melted the fuse right into the holder. In no case is it really an inspectable item before the fact and not an owner issue.
    4. You will need to get special tools to remove the wires from the fuse holder, it is not a hard process. I used the 19 pc. terminal removal kit from Steelman.
    5. I cannot stress this enough - take good notes of where each wire went. I did and then checked the electrical troubleshooting manual to confirm before I put the wires back.
    6. The part is still available if you want to buy new or risk doing the job and redo-ing it if you use a salvage part.
    7. I did take the blower motor out and checked the motor brushes (they were good). In addition I used electrical component cleaner to clean up the carbon dust from inside the motor and improved the motor's electrical resistance.
    8. Success is when the car starts and turning on the headlights do not result in the wipers moving.
    9. Good luck!
