What is the 94 Chevy Caprice Classic wiper arm

Hi roberto ismael luna, I want to help you with your question, but I need more information from you. Can you please add details in the comment box?
what country,? (the vary by....this)
those parts swaps are they OEM new or used.?
that failure is called auto park.
traditionally that is only function of the
whole wiper assembly (not motor neat) as the assembly casing has switches, to do that.
it is a safety issues. to the wipers do not stick and block your view down the road.
sure the list of possibles.
1: control arm ,mostly no. (wiper)
2: wiper, whole assembly , not just motor.
3; fuses
4: relays
5: bad wiring.
6: controllers, BCM etc?

I say #2 is bad and exactly this part black at blue arrow, CAM box
the motor is not bad ,the switch cam, does AUTO PARK.
use only NEW parts. not pulls or salvage , or Pro grade Refurbs
for CARDONE 1

Just replacing parts isn't the way to fix this problem , viewing wiring diagrams too see what all is involved in making the wipers work is . Then using a digital volt ohmmeter to test electrical circuits . Also looking at factory service info. to see how it's suppose to work.

Under system click on body & accessories , then under subsystem click on wiper/washer . Click the search button ,then click the blue link. Looking at the wiring diagram i see two fuse's an two relays that are controlled by the BCM - body control module . Also hooking up a scan tool that can read BCM DTC'S - diagnostic trouble codes could be helpful . The wiper switch is a input to the BCM - the BCM will energize the relays to turn on the wipers.

Wiper/Washer System Components
The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Body control module (BCM)
• Wiper 1 relay
• Wiper 2 relay
• Wiper diode
• Windshield wiper motor
• Windshield washer pump
• Windshield washer nozzles
• Windshield washer solvent container
• Windshield wiper arm and blade assemblies
• Windshield wiper transmission
• WIPER/SW 10A fuse
• WIPER 25A fuse

Wiper/Washer System Description
The body control module (BCM) controls wiper motor low speed operation. The washer pump and high speed operation are controlled directly by the wiper/washer switch. The windshield wiper/washer switch supplies voltage on the signal circuits to the BCM for windshield wiper/washer operation. When WASH, MIST, DELAY, LOW, or HIGH is detected, the BCM energizes the wiper 1 relay by suppling voltage to the relay coil. This allows battery voltage from the WIPER fuse to flow through the relay switched input then through the contacts and out the relay contacts to the wiper 2 relay switch contacts. Since the wiper 2 relay switch contacts are normally closed to the low speed circuit of the windshield wiper motor, the motor will operate at low speed.

Windshield Wiper/Washer System Components
The windshield wiper/washer system consists of the following components:
• Windshield wiper/washer switch
• Windshield wiper motor
• Windshield washer pump
• Windshield washer relay
• Outside moisture sensor
• FRT WIPER 25A fuse
• W/S WASH 15A fuse
Windshield Wiper/Washer System Operation
Accessory voltage and ground is supplied to the windshield wiper motor and provides the power for operating the wiper motor and logic power to the wiper motor module. The WASH, MIST, LOW, and DELAY modes are controlled by the windshield wiper/washer switch through a series of internal resistors. The windshield wiper switch supply voltage circuit is a 12-volt reference from the wiper motor module to the wiper/washer switch, and the switch position determines the point on the resistor assembly where the reference voltage is applied. The windshield wiper switch signal 1 circuit supplies the voltage from the resistor assembly to the wiper motor module and the signal voltage determines the operating mode. High speed operation is controlled by the windshield wiper/washer switch through the windshield wiper switch high signal circuit. The windshield wiper switch high signal circuit is supplied 12 volts by the wiper motor module and when the wiper/washer switch is turned to the HIGH position the windshield wiper switch high signal circuit is grounded through the switch ground circuit. The windshield washer pump is controlled through the windshield wash relay. The windshield wash relay coil and switch is supplied battery positive voltage, and during WASH mode the wiper motor module grounds the washer relay control circuit energizing the relay. When the relay is energized battery positive voltage to the switch side of the relay is supplied to the washer pump control circuit.

The is the symptom of a defective wiper switch.

There should be a nut on the end of the wiper motor drive arm that connects the wiper transmission to the wiper motor assembly that needs removal

Possible wiper linkage has broken/seperated from wiper motor. The wiper cowling covering the linkage assembly will need to be removed to inspect/repair

Wiper Arm & Blade (Front) Removal & Installation Wiper Blade To Remove:

1. Turn ignition switch to ACCY position.
2. Turn wiper switch to PULSE position and turn ignition OFF when wipers are stopped in the innerwipe position.
3. Push the wiper blade clip button IN and remove wiper blade from wiper arm.

To Install:

1. Insert wiper arm hook through opening in wiper blade.
2. Place wiper blade pivot in the inside radius of wiper arm hook.
3. Pull on wiper blade pivot into hook until it locks into place.
4. Check wipers for proper operation.

Wiper Arm To Remove:
NOTE: Mark position of wiper blade on windshield to ensure proper position upon reassembly.

1. Remove washer hose.
2. Lift wiper arm from windshield and use a screwdriver to disengage retaining latch.
3. Remove wiper arm from shaft.

To Install:

1. Place wiper arm on shaft so that wiper arm aligns with marks placed on windshield.
2. Press arm assembly on shaft and push retaining latch IN.
3. Connect washer hose.
4. Remove windshield markings and check wipers for proper operation.

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.
