A friend of mine's car has develop a hatred towards fuses.

The car is a G Reg Mk4 Escort 1.3 Popular Plus, and for some reason rejects fuses that are placed for the use of wind screen wipers.

When a new fuse is in the fuse box, a turn of the key to switch the electrics on, and the fuse blows instantly. This happens no matter what state the car is in (hot, cold, wipers on or off etc), so far (touch wood) nothing else has made itself known to the repair list.

A couple of times the wiper fuse doesnt blow when the fuse box cover is off, but thats only a few times.

Anyone have any suggestions ?
