Escort 55 1.8d van fuse 25 keeps blowing and cant start my van.circuit says wiper and washers and it wont let me install new fuse without blowing.i have work on monday !Help!

U have a short in the circuit that feeds the washer motor.

In the under hood fuse box , should have diagram inside the lid . Front wiper's or rear ? Front fuse # 36 - 25 amp. Plus Two relay's PCB hi and Wiper PCB relay . Wouldn't think this being fuse problem . Wiper switch , motor etc... The wiper's are control by a computer . BCM - body control module .

The windshield wiper/washer system consists of front and rear wipers. The front and rear wipers are operative when the vehicle is in accessory or run. The front wipers have 4 different modes: Mist, Intermittent, Low, and High. When the front wipers are in the intermittent mode, there are 5 delay modes to chose from, commanded by the windshield wiper washer switch through the body control module (BCM). The rear wipers has an only one mode.

If the fuse is bad , could have a short to ground or wiper motor pulling to much current (amps) . Fuse's don't just blow for no reason ! Could also have DTC'S - diagnostic trouble codes stored in the BCM .

DTC B3715 02: Front Wiper Relay Drive Circuit Short to Ground
The body control module (BCM) controls the wiper motor based on input from the windshield wiper washer switch. The BCM monitors the wiper washer switch through three separate signal circuits and a ground circuit. The windshield wiper switch high signal circuit is used to determine high speed wiper operation, the windshield wiper switch low signal is used to determine low speed, intermittent, and mist operation through the use of a resistor ladder, and windshield washer switch signal circuit is used to determine washer operation.
The BCM controls the windshield wiper motor through two output controls, controlling two different PCB relays which control the desired wiper speed, high or low.

The PCB relay's are non- servicable , replace fuse box . Soldered in Your best bet mit be to take it to a qualified repair shop .

Wiper/Washer System Components
The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Body control module (BCM)
• Wiper PCB relay
• Wiper high PCB relay
• Windshield wiper motor
• Windshield washer fluid pump
• Windshield washer fluid level switch
• WPR fuse 25 A
• WSW fuse 10 A
This is more then likely not a fuse issue !!!!!!!
Low Speed Operation
When the wiper switch is in the low speed position, ground is applied through the switch internal resistor and the wiper switch low signal circuit to the body control module (BCM). In response to this signal, the BCM energizes the WIPER PCB relay by applying battery voltage through the wiper relay control circuit to the coil side of the relay. This allows battery positive voltage from the WPR fuse to flow through the switch input side of the WIPER PCB relay and out to the switch input side of the WIPER HIGH PCB relay. Since the wiper high relay is de-energized and its switch contacts are normally closed to the low speed control circuit of the windshield wiper motor, the motor will operate at low speed.
Wiper motor low speed operation and the wiper PCB relay can also be commanded ON/OFF by using a scan tool. Refer to Control Module References.
The PCB relays mentioned above are soldered right into the circuit board inside the fuse/relay block under the hood . There are alot of reasons for the wipers not to work ! The fuse could be blown but fuse's don't just blow for no good reason , short to ground , low resistance high current flow etc.... Intermittant !

Power and Grounds
With the ignition in the ON position, accessory voltage is supplied through the 25A WPR fuse to the WIPER PCB relay, the WIPER HIGH PCB relay and the WS WASH PCB relay that are all located in the underhood fuse block. Refer to Wiper/Washer Schematics.
G200 provides ground for the windshield wiper motor and the WIPER PCB relay. G100 provides ground for the windshield washer fluid pump and the windshield washer fluid level switch.

Usually, the washer circuit is part of the wiper circuit. If your wipers work, the washer's pump wire should have voltage on it when the washer is turned on. If it does, probably need a new washer pump. The wiper fuse is usually in the main fuse panel under the dash, look for a 25 amp or larger fuse.

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.

Sounds like the circuit is being overloaded , have you had any rescent add ons like an alarm or remote start maybe even a new stereo? If no to any add ons you may want to move the wipers off the windscreen and run them for the ten minutes see if the fus still blows. If it does you may want to look into the mechancal arms of the wipers these contain ball and neoprene bearings these can be simply visually inspected . And made sure everythig is tight and appears in order.

The power distribution box in the engine compartment # 6 , 30 amp mini - fuse , front wiper motor , front wiper relay , front washer pump , FEM ( also # 7 , 25 amp mini - fuse , rear wiper etc. ) The owners manual shows to disconnect your battery cables before servicing anything in the PD BOX

your relay could be shorted which makes the fuse keep blowing

check to see if the wiper arms are binding, something is causing a feed back to the motor to strain. Blowing a 25 amp fuse is serious, and could cause many more problems, check for a good ground, clean all grounding wires in the system for that fuse, if you wrapped the wires and it quit for a brief time, one of them could be broken or burnt to the point that when they heat up and expand they simply can't complete the circuit

Do not put a larger amperage fuse in. you run the risk of the wiring over heating and starting an electrical fire. More than likely the wiper motor is starting to go bad and is drawing an unusually large amount of current which causes the fuse to blow. Replace the wiper motor.

bottom line is that you have a short to ground in the wiper circuit

these are some of the toughest to repair

first thing you want to do is follow ALL the wires from the wiper motor and switch

inspect for anything that looks like it has been rubbed raw!

there are some tools I have that you can buy at most pro-shops, most are called short-finders

they work by applying a small current on the suspected circuit and then use a "finder" to indicate where the short is located

another old school method is to install a bigger fuse and follow the smoke! not a good choice on anything since 1980



good luck and keep us posted
