Question about 1993 Volvo 940
25amp fuse blows when ignition is tured on this is for the front wipers ,horn and screenwash
Disconnect (unplug) all the units that are supplied by the 25A fuse.
Switch on ignition and check that fuse has not blown- if it blows under these conditions the short or overload to ground is:-
a) in the wiring to one of the units,
b) or there is some other unidentified faulty unit still connected.
Re-connect each unit one at a time, observing fuse status.
If one of the units has a short / fault, it will blow the fuse when it is connected back in circuit.
