My wiper fuse keeps burning out - Cars & Trucks

check for bare wires grounding out , wiper motor failure or wiper shafts seizing up and overloading the motor
using a bigger fuse will only result in the wiring harness burning out and possible fire in the car

Does the fuse blow when the wipers are off or when you turn the wipers on? A fuse blowing means either a short circuit or an overload. Lets say that your wiper transmission is new and working properly, then an overload is probably blowing the fuse which is caused by the circuit pulling to much current because something is not aligned correctly and moving freely when the wiper motor is turned on. Before you connect the arms to the transmission, move the arm assembly manually with your hand to make sure the wipers go across and back on the windshield. This will verify that the arm assembly is moving freely and not jamming. Then turn the wiper transmission without connecting the wiper arms and see if the transmission is working properly and not blowing the fuse. This will verify that your wiper transmission is not defective. Check the wiring going to the wiper transmission for any bare spots or nicks on the wire insulation. If you have a bare spot or nick that is touching metal, the fuse will blow (this is called a short circuit). If you find a bare spot or nick on the wire use electrician tape to insulate the bare spot or nick. Usually three wraps of electrician tape around the bare spotor nick will do the job. Oh, make sure to replace the fuse with the correct amp fuse. Your car dealer auto parts can provide the information (over the phone) on the correct amp size. You can purchase the fuse at any auto parts. FYI: Too small an amp on the fuse will blow when the wiper is turned on. Too large of a fuse will cause the wiring to burn if your wipers should stop shifting and jam. Good Luck. Hope this helps.

Well first I would check the fuse box for burned out fuses. Then I would get a simple dc power tester and see if the windshield wiper motor is getting power. If you don't have a bad fuse and the motor is still getting power I would say the motor has burned out.

Troubleshoot the wipers. First disconnect wipers from under the hood. Replace the fuse. If the fuse still burns out then the problem is with the harness. There is a short in one of the wires and will need to be replaced.
If you replace fuse and it does not burn, then the problem is with the wiper motor. You can possibly just replace the circuit board or replace the whole wiper motor.


Good Luck,

If fuses keep blowing, then there is a dead short somewhere,. My advice would be to go to an auto electrician. You did not mention for which circuit/s the fuses blow.

Check your wipers are parking in correct position -if there has been slippage at their attachment spigot they may be jamming the motor during use causing fuse failure.
Check for overload on any other circuit that may be sharing the wiper fuse.
Check wiper fuse is a firm fit in the fuse holder, and making good electrical connection.

Hi
Expect you have blown the fuse !

Get a torch.
Look under the dash foot well panel, and lift off the fuse box cover, on the back of the cover look for wiper pic, this will show you the fuse location.
Pull out the fuse, with the little red tong tool, that should be in the fuse box, or just your fingers.
You should see the little bridge wire melted across the top of the fuse ?
You should have a spare fuse in the fuse box.
Put it in, and switch on the wipers !

Good Luck !

Please give me a FixYa rating, I wan´t to be a Guru !

If the fuse blows as soon as you put it in and the wipers are off then you have a short between the fuse block and the wiper switch.

If the fuse blows only when you turn the wipers on then more than likely the wiper motor has shorted and burned out. This one is very likely if the snow storm was heavy and you was driving in it. Cause- Moving large amounts of snow and ice off the window puts a heavy load on the wiper motors.

there is a short check your wiper motor.

Check that the wiper arm pivots are not seized, spray lubricant a try to check free movement.
