Question about 1994 Ford Crown Victoria

2 Answers

Wipers don't work in high speed and when intermittent wipers are set they stop in the middle of the windshield.

High speed wipers don't work and intermittent setting causes the blades to stop in the middle of the windshield. Is this a multi function switch problem?

Yes that is likely a switch problem. Before you buy any parts have a shop confirm my guess.

That's normal on some cars.
Did it ever work intermittent at hi speed?
My car is wired to go intermittent only at low speed.
Hope this helps.

have you had any recent work done near the wipers? .if no the linkage from the wipers to the motor has come out of adjustment, there is a removeable cover above hood, and below winshield to see and repair as needed.. good luck marty

Try replacing relay for wiper with another same relay from fuse block from another working accessory.Had same issue on friends Ford Ranger. Moved relays and cleaned harness connection at fuse block. Works fine.

SOURCE: My wipers do not work on low and intermittent

the 89 may have a wiper control module that needs to be replaced... how many wires connect to the wiper motor? if more than two the module is built in. if only two then the module is re,ote mounted and probally under the drivers side dashboard

SOURCE: winshield wiper works on high

This solution applies specifically to a 91 Ranger with delay wipers, but may apply to other years as well:

There is a "cold solder" joint on the wiper control module that should be investigated whenever intermittent wiper issues crop up. I dont have the ability to post a schematic, but it is one of the leads that come off of the main terminal, and is fairly large. The solder around the lead will look dull and will most likely show physical separation from the circuit board itself. Re-solder with a good hot iron and it may well cure what ails ya. Takes 30-45 minutes, depending on how adept you are at worming your way under the dash to retrieve the module. It's to the left of the ashtray about 6 inches.

I have a 2009 gmc sierra, where is the wiper relay location.


The PCB wiper relays are soldered directly to circuit board inside the under hood fuse box.
The windshield wiper/washer switch signal circuits are inputs to the body control module (BCM) and the BCM controls wiper motor low speed operation, washer pump and high speed operation. The windshield wiper/washer switch is provided a low reference from the BCM and each of the switch signal circuits is supplied 12 volts through a resistor and monitored within the BCM. During LOW or INTERMITTENT operation the wiper switch low signal circuit is closed to the low reference circuit through a series of resistors within the switch assembly and the signal circuit voltage monitored by the BCM will depend on the switch contact location to the resistor assembly. During HIGH or WASH operation the high and wash switch signal circuits are closed directly to the low reference circuit within the switch assembly and nearly all the signal circuit voltage will be dropped across the BCM resistors. The BCM controls the wiper motor through the WIPER CONTROL PCB Relay and the WIPER SPEED PCB Relay. During any wiper motor function that uses low speed the BCM supplies the voltage to energize the WIPER CONTROL PCB Relay and battery voltage will be supplied from the WIPER CONTROL PCB Relay through the de-energized WIPER SPEED PCB Relay to the wiper motor low speed control circuit. During high speed wiper motor operation the WIPER CONTROL PCB Relay is energized as in low speed and the BCM provides a ground to energize the WIPER SPEED PCB Relay and the battery voltage is supplied to the wiper motor high speed control circuit. Wiper motor park operation is controlled by the BCM using an input from the park switch within the wiper motor assembly. The BCM supplies the park switch signal circuit 12 volts through a resistor then monitors the circuit. Whenever the wiper motor is out of the park position the park switch signal circuit is closed to ground and nearly all the signal circuit voltage will be dropped across the BCM resistor. When the wiper switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the BCM will continue to operate the motor until the wipers reach the park position. If the ignition is turned OFF while the wipers are in mid-cycle, the wipers will stop immediately where they are and the BCM will park the wipers the next time the ignition is cycled ON.

DTC B3715 02: Front Wiper Relay Drive Circuit Short to Ground
DTC B3875 00: Wiper High Speed Relay Circuit
DTC B3922 00: Front Wiper Function Select Circuit
Have it checked for DTC'S - diagnostic trouble codes .

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 relays which determine the desired wiper speed, high or low.
Your best bet , take your vehicle to a qualified repair shop or dealer . Hooking up a factory scan tool to see what the wiper switch inputs to the BCM are correct and outputs to relays are good .

What would cause the windshield wipers on my recently purchased Jeep Patriot Sport work on every speed except the high speed. High speed doesn't work at all.


The intermittent switch has a bad contact in it for the high speed, i would say, most likely will have to replace it.

What is the relay location in the relay box


The problem would be in the stalk controller. The wiper Relay is what provides power to the motor for all settings, the delayed wipers, low speed, and high speed. There are not 3 relays, but 1 for all functions. If you have power to the high setting, the relay is working.

Intermittent wiper


what car, what year? gee? a suz, what?
it can only be 4 things. (all cars)
1: the wiper motor is bad. (it has contacts inside for timing.
2: the wiper shaft is stripped, nah you said both stalled.
3: the wiring is bad.
4: the combo switch for the above is bad.

DIY, with what , no tools? no meter.?
with no tools one can only GUESS,
roll dice, and replace a part.
after spending $500 on parts and the wires are good then what.
yes, buy a meter.

it could be a bad ground wire.

when you turn on most wipers, the combo switch sends
that signal( just 12v ) to the motor.
the motor is self booting, that is , it only needs the start up
and then it self provides its own power,
ive restored wiper motors, many.
then the motor runs until it his the dead spot in ITS, internal
sustain switch and the halts. if the combo switch is off.
but if the wiper fails to return, this is a bad wiper motor.
(overloaded by ice, sure)
the motor can fail 2 ways, but
id say the sustain switch is at EOL. end of life.

this is the most common design.
check your FSM for yours. the factor service manual.
or alldata dot com. sure.

1998 olds silhouette mini van, passenger side wiper arm over extends off the wind shield when turned on. When this happens wipers seem to be running at maximum speed or beyond really hammering the stops....


when the wipers are off make sure the driver and passenger wipers are at same level on windshield
you can adjust them so they don't go off the edge or hit the bottom.
if they are hitting off the edge and hitting the bottom as well you need to check the linkage since it may be worn out.

Windshield wipers work but interminent settings don't


most likely cause is the wiper switch has gone bad and unable to 'time' the intermittent speeds.the intermittent speeds work on a resistor type system where low and high speeds add direct voltage.
