1981 Chevy El Camino Wiper motor

My wiper motor has stopped working, of the 3 wires that operate the motor only 1 recieves any power when the switch is activated. I have replaced the motor and switch and still have the same issue. All fuses are good and you can hear the motor click when turned on but that is all it does, if left on for more than a few seconds the electronics in the motor start to smoke.

I put a new wiper motor and washer on my 1978 El Camino. They come on and work fine but won't turn off. could this be the switch or relay somewhere?


hi David.
this is all i could find out.
The fuse is the safety device that breaks the electric circuit if it exceeds the safe level. If your fuse blows then there will be no way to stop the electricity from reaching the windshield wipers. This will cause your wipers to constantly keep going. ... You can easily tighten it and the wiper problem should be resolved.26 Feb 2013

Where to find the window wiper motor? How to know if it is bad and if replacing it will fix my wiper fluid problem in my 85 el camino. wipers work fine but no spray does not. maybe fuse?


If I remember correctly, your wiper motor is mounted to the firewall, likely on the drivers side. You can locate it easily by turning the key on and turning on the wipers. Just listen to the motor and follow the sound. To see what's going on with the washer portion, you need to carefully remove the plastic cover.
If you have a circuit board inside, be careful not to break it. You need to look at the pump and pump actuator to see what's working or not. (check for voltage and mechanical operation)
To fix it, you can sometimes get a pump rebuild kit but if the electrical part isn't functioning, unless you are trying to keep the car absolutely stock, there are aftermarket external pumps you can add on, using a push button on the dash. It's an easy install and far cheaper than replacing the entire wiper motor assembly. Another option is to go to a scrapyard and find a fluid reservoir from a Chrysler or any other car that uses a pump on the reservoir. Find one that fits reasonably well in your engine compartment and just attach the hoses to your system. Then all you need is a wire from a power source to the push button, then to the pump, and a ground for the pump housing.

Front wipers will not operate. checked fuse and relay look ok. back wiper works


Here are a few other things to check beside the fuse and relay:

Check Wiper Motor - the wiper motor is the driving force of the windshield wiper. Feel the motor and listen to a humming sound. If there is no humming, the motor is the problem. Check if the motor is working properly and see to it that its electrical connections are made properly. If you find that the motor is dead and beyond repair, get it replaced immediately.

Check For Break in Connecting Wires - the connecting wires of the motor sometimes go loose and that may cause the windshield wipers to stop working. Also check the battery plug connection which the motor has. Connecting the loose wires properly or fixing/replacing the plug might solve your problem.

Check Wiper Switch - another wiper assembly part that can malfunction is the wiper switch itself. Check for switch malfunction and if you find that is indeed the problem, get it replaced from a mechanic.

Check for Bent Wiper Arms - bent wiper arms can cause the operation of the wipers to be hampered. If the wiper arms are bent beyond repair, get them replaced immediately.

Wipers don't work on intermittent. They run but stop in they middle of the windshield and don't go to the bottom like normal, Then they run again and stop some other spot. When put on continuous they...


Intermittent Speed Windshield Wipers
The intermittent wiper speed is activated with grounds controlled by the multifunction switch inputs to the windshield wiper motor module. The windshield wiper motor module then activates the windshield wiper RUN/PARK relay coil and switches voltage through the windshield wiper high/low relay. The high/low relay remains deactivated supplying the voltage to the wiper motor low speed input and activates the windshield wiper motor. When the windshield wiper motor module receives the grounded input, the motor continues to operate until Hall effect senses magnet to turn off RUN/PARK sense the output to the windshield wiper RUN/PARK software, deactivating the relay and disconnecting voltage to the wiper motor. The windshield wipers remain parked until the windshield wiper motor module completes a time-out and then repeats the intermittent windshield wiper cycle.

  • The intermittent windshield wiper speed does not operate correctly
  • Multifunction switch.
  • Circuitry.
  • Windshield wiper motor.
  • Go To Pinpoint Test D .

Pinpoint Test D: The Intermittent Windshield Wiper Speed Does Not Operate Correctly
Normal Operation During normal operation, the windshield wiper motor receives voltage at all times through battery junction box (BJB) fuse 1 (30A), circuit 65 (DG). The windshield wiper motor also receives power with the ignition switch in RUN or ACC positions through central junction box (CJB) fuse 33 (15A), circuit 1002 (BK/PK). Ground is provided to the windshield wiper motor through circuit 676 (PK/OG) and circuit 57 (BK). The run/park and high/low relays are contained in the wiper motor electronics. Mode of operation is dependant on the signal(s) received from the multifunction switch.
    Possible Causes
  • Multifunction switch
  • Open in circuit 57 (BK), 56 (DB/OG), 61 (YE/RD) or 63 (RD)
  • Windshield wiper motor
PINPOINT TEST D: THE INTERMITTENT WINDSHIELD WIPER SPEED DOES NOT OPERATE CORRECTLY Test Step Result / Action to Take D1 CHECK THE MULTIFUNCTION SWITCH
  • Key in OFF position.
  • Disconnect: Multifunction Switch C202b.
  • Carry out the multifunction switch component test. Refer to Wiring Diagrams Cell 149 for schematic and connector information.
  • Did the multifunction switch pass the component test?
Yes
GO to D2 .

No
INSTALL a new multifunction switch. REFER to Section 211-05 . TEST the system for normal operation. D2 CHECK CIRCUIT 57 (BK) FOR OPEN
  • Measure the resistance between multifunction switch C202b-6, circuit 57 (BK), harness side and ground.
  • Is the resistance less than 5 ohms?
Yes
GO to D3 .

No
REPAIR the circuit. TEST the system for normal operation. D3 CHECK CIRCUITS 56 (DB/OG), 61 (YE/RD) AND 63 (RD) FOR OPENS
  • Disconnect: Windshield Wiper Motor C125.
  • Using the following table, measure the resistance between multifunction switch C202b harness side and windshield wiper motor C125 harness side:

    Multifunction Switch C202b Windshield Wiper Motor C125 Pin 2, circuit 56 (DB/OG) Pin 10, circuit 56 (DB/OG) Pin 4, circuit 61 (YE/RD) Pin 1, circuit 61 (YE/RD) Pin 1, circuit 63 (RD) Pin 9, circuit 63 (RD) Pin 3, circuit 58 (WH) Pin 11, circuit 58 (WH)
  • Is the resistance less than 5 ohms?
Yes
GO to D4 .

No
REPAIR the circuit(s) in question. TEST the system for normal operation. D4 CHECK FOR CORRECT WIPER MOTOR OPERATION
  • Disconnect all wiper motor connectors.
  • Check for:
    • corrosion.
    • pushed-out pins.
  • Connect all wiper motor connectors and make sure they seat correctly.
  • Operate the system and verify the concern is still present.
  • Is the concern still present?
Yes
GO to D5 .

No
The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. TEST the system for normal operation. D5 CHECK THE WINDSHIELD WIPER MOTOR
  • Key in OFF position.
  • Disconnect: Windshield Wiper Motor C125.
  • Carry out the windshield wiper motor component test as outlined in this section.
  • Did the windshield wiper motor pass the component test?
Yes
The system is operating correctly at this time. Concern may have been caused by incorrect binding pivot arm adjustment. REFER to Wiper Blade and Pivot Arm Adjustment in this section. TEST the system for normal operation.

No

Windshield Wiper System The windshield wiper system consists of :
  • Windshield wiper motor (17508) (F-type).
  • Washer system.
  • Windshield wiper control module.
  • Turn signal and windshield wiper switch (13K359).
The windshield wiper control module is:
  • Located at the instrument panel fuse panel.
The windshield wiper motor is:
  • Attached to the cowl top extension (021A36) .
  • Connected to windshield wiper mounting arm and pivot shaft (17566) .
The turn signal and windshield wiper switch features a:
  • Rotary wiper switch.
  • Push type washer actuator.
OFF/Low/High Speed
  • Has a two-speed, permanent magnet, three brush electric windshield wiper motor .
  • The windshield wiper motor has a brush rigging that permits selection of low or high speed.
  • When the turn signal and windshield wiper switch is in the LO position, the common brush and the blue/orange wire brush are used, and the windshield wiper motor operates at low speed.
  • When the turn signal and windshield wiper switch is in the HI position, the common brush and the white wire brush are used.
  • In HI position, electric current will bypass a portion of the armature winding causing the windshield wiper motor to operate faster.
  • When the turn signal and windshield wiper switch is moved to the OFF position, the windshield wiper motor will continue at low speed until the park switch outer contacts open.
  • When the park switch contacts open, the windshield wiper motor stops in the park position.
Interval
When the turn signal and windshield wiper switch is in the interval position:
  • The wipers make single wipes separated by pauses.
  • The rotary switch is on the end of turn signal and windshield wiper switch .
  • The length of the pause can be set from approximately 1 to 17 seconds.
  • Length of pause decreases as the rotary switch is rotated away from off.
  • Length of pause increases as the rotary switch is rotated toward off.
While in the interval wiper mode:
  • It is normal to hear a slight click at the beginning of each on/pause cycle. NOTE: When using interval wipers, the first wipe may not occur until after a pause of up to 17 seconds.

Hey scorpio13206,

Thanks for asking me about your wiper problem. I've got to let you know up front that this could be a multi-step process (perform a test, the results determine the next step). I'll also be asking some questions to get a better grip on where the problem may be. I'll explain what I'm asking
so you can better help me help you. Just comment me back with your findings.

I know people have jobs and lives. I don't expect an immediate response so don't worry about it. It's important that you take your time, be safe.

If you have something you can use to test voltage (test light or volt meter), get it out. You will also need A length of wire, preferably with clips on the ends (just to keep your hands free) to supply voltage for some of the tests.

Be patient. You are my eyes and ears. From the way you described the problem, you won't have a any trouble, we're going to do great. Let's get started.

Questions:
  • The pulled wire, how was it connected? (just curious)
  • When you grounded the wire from the wiper motor, did it spark? Was the ignition and/or the wiper switch on at the time?
  • Is the delay after market?
  • Were the fuses checked again after the wire was grounded? (I figured you wouldn't pull a wire if nothing was wrong, you would've checked fuses before pulling wires, so....)
  • Wiper motor: How many wires come out of it? (some motors have multiple speeds wired into them (two to four wires), others are controlled by an electric pulse (one or two), some have after market delays wired in)
  • Did the pulled wire look like it was added or was it original from manufacturer?
Tests:
  • After you have confirmed the fuses are ok again. On the wire that was pulled, test it for voltage with the ignition and wiper switch on.
  • Need to know the wiring config before I put any test power to the motor.
Get back to me when you can.
Mike
