Question about 1984 Chevrolet K1500

1 Answer

Wiper/Washer Motor My washer motor has stopped working. It is mounted within the wiper motor housing. It is controlled with a steering column lever (also cruise control and blinkers). It has low, delays, and a high setting. There are three connector ports on the body of the wiper motor. The lower on consists of 3 wires: Purple, Gray, and White. The mid-connector has 2 wires: Pink and. The upper connector has 2 wires: black w/blue line and gray. When disconnected, the lower connector only has power to the purple wire. When connected, the purple wire supplies power to the other two wires, which run into the fuse panel. They then return to the other two connectors. The mid connector supplies it's other wire when connected as well. The upper connecter has 1 power wire and 1 ground wire. This is all without touching the wiper switch. I have a replacement washer motor that is an in-line device. I cannot figure out which wires to connect to the motor. The upper connector's wires run my new pump non-stop, the mid-connector doesn't run it at all, and I haven't tried the lower connector because they are all powered. Please Help.....

You may have bought a constant wiper motor, rather than one with intermittent settings. It happens.

2000 ford ranger wipers only work on hi speed & won't turn off until later in pull the fuse. Also they will work by pushing the washer button & will turn them self off.


Obtain a scan tool with bi-directional control capability. Monitor functions and input/output from General Electric Module (GEM or Body Control Module). I would suspect usually the wiper motor itself (control board internal to the wiper motor) or the multi-function switch on the steering column.

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 .

1996 horn doesn't work but alarm does


I had to go to a salvage yard and purchase an air bag (which include the horn contacts) to repair my horn. The wiper washer could be a list of things. Does your fluid run out on the ground? - broken washer hose? Listen by your lower right front fender behind the wheel and have someone push your washer lever and see if you can hear the pump running. If not, could be a pump motor (check with a test light after pulling the inner fender) or the multi-function lever in the steering column.

Fuse blows everytime I attempt to use the washer fluid.


really?! the water pump?! the water pump has nothing to do with your wipers it is part of the COOLING system. as for your issue...it could be a short in the wiper/signal arm in the steering column, or it could be the motor in your washer fluid bottle. the motor is what pushes the fluid through to your windshield and if its gone bad it will blow your fuses as well. i would start with the washer fluid reservoir motor and go from there

If both the wiper motor and the washer motor do not work, then it is the 25 amp fuse, or the wiper control module in the dash...possibly the switch in the steering column, but I doubt that...

The wiper motor on my 1983 Ford Ranger still works but the wipers no longer move. I think there is a failure of the mechanical linkage. Where do I go to find repair parts?


why do you think the motor still works if the wipers don't move? Can you hear the motor run or can you see a little movement when you turn the switch on?

What happens when you activate the washers?

go to a salvage yard that allows you to remove the parts yourself. Then you can see how the motor and linkage assembly comes out.


don't have 1983 info, but here is 1994:

Section 01-16A: Wiper and Washer System, Ranger/Explorer 1994 Ranger and Explorer Vehicles Workshop Manual
DESCRIPTION AND OPERATION Windshield Wiper System, Ranger/Explorer The windshield wipers are actuated by a permanent magnet, rotary-type electric windshield wiper motor (17504) . The two windshield wiper pivot arms (17526) and windshield wiper blades (17528) are mounted on a pivot shaft, one at each side of the windshield. The windshield wiper mounting arm and pivot shaft (17566) are connected to the motor by windshield wiper adapter and connecting arm clip (17531) . Ranger and Explorer vehicles are equipped with an interval wiper and washer (IWW) system featuring a lever-type turn signal and windshield wiper switch (13K359) mounted on the steering column. The IWW windshield wiper governor (17C476) uses a relay contact to control current to the windshield wiper motor . The governor electronic circuitry controls the contact to supply current to windshield wiper motor . A rear wiper/washer system is available on Explorer vehicles. The rear window wiper system consists of a windshield wiper motor mounted inside the liftgate (40010) , an articulating windshield wiper pivot arm and windshield wiper blade , a windshield wiper/washer switch (17A553) and an inline circuit breaker. The front electric windshield washer system consists of a control switch, integral with the turn signal, a windshield washer reservoir (17618) and windshield wiper motor and the necessary windshield washer hoses (17A605) , windshield washer nozzle jet and brackets (17603) and attaching parts.
