Wind screen wipers fuse is blowing up again and again (1 Viewer)

Hi,

The fuse keeps blowing up. Once I put in a new fuse, wipers work. Next time when I need wipers they don't work and fuse is blown.

Started happening since I washed my engine bay (

Keep the pressure washer out of the engine bay.
Follow the wires from the wiper motor looking for anything unusual bare wire anything that would cause a short, you may have water in the motor itself.

How long has it been since you washed the engine bay?
Did you spray water directly at the wiper motor/wires?
Has the wiper motor been making any new/louder than usual noise while running, growling??

IME the magnets can pop off the inside of the case and drag on the armature (causing growling) or can lock up the armature
causing the motor to get very hot (pulling amps) with no movement.

Already mentioned, disconnect the harness connector at the wiper motor, clean with Electrical/contact cleaner (not Carb or Brake cleaner),
reconnect.

Just used a quick garden hose spray to clean the area around that wiper motor and its wire couple of weeks. Been on a long trip after that and everything else been working well.
No griding noise from the motor when using the wiper blades. I will spray wd-40 in the connector, replace fuse and check again.

I would not use wd40 on an electrical connection, use electronics cleaner. WD40 originally meant "water displacement" but now there are multiple types of WD40 which AFAIK are either penetrating oils and/or lubricants.
