2012 ranger 2.2 the intermittent wipers don't work. If switch on it run the same speed as the first continued speed. Already replays the switch

There are two relays, a diode, BCM, multifunction switch, and all the wiring/connectors between. There are two power inputs to the wiper motor that determine speed. The BCM interprets the selections from the multifunction switch and commands the two relays for speed and intermittent.

Start at the wiper motor and verify low speed power is not being provided and work your way back through the relays, then the BCM, and the multifunction switch.

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.

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.

1) It is normal for the wipers, in rain sensor mode, to cycle once upon startup.

2) In rain sensor mode, the wipers should be intermittent with the cycles increasing as the volume of moisture increases on the windshield. The speed will increase until it reaches the continuous slow speed of position 2 on the switch. It will not increase to the fastest speed which is position 3 on the switch. You have to go to the fastest speed by manually rotating the switch to postion 3. Doesn't seem like a design flaw to me.

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
INSTALL a new windshield wiper motor. REFER to Windshield Wiper Motor in this section.

Mazda is the same as a Ford Ranger. There is a wiper relay under the dash that goes bad. It will work on fast but not slow or delay. Just take the cover off and follow the wires from the lever or switch on the column and they will lead to a box, which is the relay. Then the wires goes out to the motor. I had this problem on two trucks.

i belive that your wiper switch has gone out on the intermittent side. this is a very common problem.
I hope this helps you
Thanks

Wiper Motor Switch Troubleshooting Check out someother GM wiper fail's video's ,not shuting off means the park switch is bad inside the motor assembly ,u need a new motor .

try replacing the wiper relay

or could be a faulty wiper intermittent part of the switch

The wiper switch is most likely bad. Check the coolant level for the temp. issue. Low coolant will cause a gauge to shoot up suddenly
