    95 GMC K2500, and fuse # 16 in the cab for the Turn Signal/Backup lamps blows each time the key is turned on. This is the only fuse that is blowing. Took a quick peek at wiring harness from cab to taillights, looks just fine, no rubbing anywhere or splices etc. I am in the process of getting a wiring diagram, but I am curious if any of you have seen this problem and if there is an item that perhaps is common.

    The fuse blows as soon as I turn on the

    key, blows immeadiatly. Hazards work fine, looked closely at loom at drivers rear taillight, looks fine.

    Just noticed this thread...did you get it figured out?

    The '95's had a problem with the wiring harness that runs up the steering column to the multi function switch- which of course includes the turn signal wiring and will pop the turn/BU power fuse if this harness is chafed or pinched.

    Easy test is to disconnect the multi function harness connector at the steering column and then turn the key on. If it no longer pops the fuse instantly, you'll know your in the ballpark.

    Thanks B&B, I will check it out and will keep

    you posted, I assume it is the multi-wire connector to the left of the column.

    Just an update for B&B, the pink wire to the

    left of the column in the harness that runs from the fuse box was rubbed through, repaired the wire, and it seems just fine. As always I appreciate the assistance from all on this site.

    Take Care,
