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.
Does the fuse blow as soon as you turn on the switch? Or do the wipers operate for a bit then the fuse blows? Will the wipers work in intermittent mode? Can you move the wipers by hand? Unless other wiring work has been done (eg radio replaced) I suspect the wiper motor is toast.
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.
When the fuse for the wipers keeps blowing, that means either the motor has a dead short within it and must be replaced, or the wiring going to the motor is damaged and shorting out on the vehicle body somewhere and must be repaired.
Here is how you check it; replace the blown fuse, unplug the connector from the wiper motor, then turn the key on if the fuse does not blow then you need to check the wiring to the motor if the wiring is not damaged anywhere replace the wiper motor.
