Wiper motor only runs on high.

New wiper motor, only runs on high, for 20+ minutes then sometimes other modes work. Seems like a capacitor problem.

That sounds to me like a problem with the switch, or a relay (not a capacitor). Try replacing the switch on the stalk and see if the issue goes away. You can check the voltage and test at the motor to see what signal is being sent to the wiper motor.

2005 crown vic. p71v 1st the fluid stopped and the wipers would'nt shut off, now 1 day later no fluid still and the wipers stop working completely, please help me


Principles of Operation
The windshield wiper motor receive inputs from the following:
  • multifunction switch
  • lighting control module (LCM)
  • ignition switch
  • battery junction box (BJB)
  • central junction box (CJB)
The following components are integrated into the windshield wiper motor:
  • windshield wiper motor module
  • high/low speed relay
  • run/park sensor (Hall effect)
  • washer pump relay
High Speed Windshield Wipers
High speed is activated when the multifunction switch supplies ground to the windshield wiper motor module inputs. The windshield wiper motor module then supplies ground to the run/park sensor and high/low relay coil, activating the relay with voltage supplied from the ignition switch (RUN/ACC) through the central junction box (CJB). When the windshield wiper motor module receives voltage from the run/park sensor, it removes ground from the run/park sensor, deactivating it. The windshield wiper motor continues to operate from voltage connected through the run/park sensor until the Hall effect senses the magnet in the motor. When the Hall effect senses the magnet in motor the windshield wiper motor returns to the park position, the internal run/park sensor grounds the windshield wiper motor module input and the windshield wiper motor module removes ground from the windshield wiper high/low relay coil, deactivating the high/low relay and windshield wiper motor. The windshield wiper motor module continues to cycle the windshield wipers until the inputs from the multifunction switch are changed from the high speed position.
Low Speed Windshield Wipers
Low speed is activated when the multifunction switch supplies a specific ground to the speed inputs of the windshield wiper motor module. The windshield wiper motor module then supplies ground to only the windshield wiper run/park relay coil, activating it. When the windshield wiper run/park relay is activated, the deactivated windshield high/low relay connects voltage to the windshield wiper motor low input activating the wiper motor. The windshield wiper motor module continues to operate the windshield wiper motor in the same manner as in high speed, but in low speed with the wiper motor connected to the low speed input.
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 sensors senses the wiper motors magnet, which turns off the run/park sensor 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.
Washer System
The windshield washer is activated by the internal wiper motor module when it receives a ground from the multifunction switch between the washer input. Dependent on the correct ground, the internal wiper motor modules activates the windshield washer relay (internal) by grounding the respective relay coil. When the relay is activated, it connects voltage to the washer pump while the washer level switch provides ground to the washer pump.
Default Mode
The windshield wiper motor defaults to this mode when the run/park sensor does not sense the hall effect magnet inside wiper motor. This can be caused by obstruction of the windshield wipers or a binding linkage. The windshield wiper motor will continue to operate in a high/low speed condition for a period of 60 seconds.

Why is it my 2008 chevy uplander rear wiper motor/blade moves some and stops. I let van set 5-10 minutes with key off. Turn on key. Wiper motor/blade moves a few degrees and then stops again. Why?


Can you move the wiper by hand ? Which does your vehicle have ?
WDA/Z88 The rear wiper is controlled based on an input from the rear wiper/washer portion of the multifunction switch. When closed, the wiper ON and wiper DELAY switches provide a unique voltage signal to the rear window wiper motor indicating the desired speed. Each switch has a unique resistor that drops the voltage to a specified value which is interpreted by the rear window wiper motor as ON or DELAY. The rear wiper motor receives B+ voltage from the I/P fuse block and accessory voltage from the body control module (BCM).

Where is the relay and fuse for rear wiper located ?


The rear wiper / washers are controlled by the GEM - generic electronic module .
NOTE: The generic electronic module (GEM) will not activate the rear wiper system if either the liftgate or the liftgate glass is ajar. If either the liftgate or the liftgate glass becomes ajar while the rear wiper is in operation, the GEM will park the rear wiper motor.
There are two distinct modes of wiper operation:
  • Off Mode: In this mode, there is no rear wiper activity, and the wiper motor will be in the PARK position.
  • Interval Mode: This mode is selected when the rear wiper switch is in either the Interval 1 or 2 position. When this mode is selected, the rear wiper motor is driven up onto the glass by activating the rear wiper UP relay. When the wiper motor HIGH/LOW/PARK position input reaches the high position, the UP relay is deactivated and the DOWN relay is activated to reverse the wiper motor direction. When the wiper motor reaches the LOW position, as determined by the HIGH/LOW/PARK position input, the GEM deactivates the DOWN relay and will begin a new wiper cycle 1 to 10 seconds later, depending on the interval position selected.
Inspection and Verification
  1. The wiper/washer system is a generic electronic module (GEM) controlled system; refer to Section 419-10 .
  1. Verify the customer concern by operating the wiper/washer system.
  1. Visually inspect for obvious signs of mechanical and electrical damage.
Visual Inspection Chart Mechanical Electrical
  • Hoses to windshield washer pump
  • Wiper linkage
  • Fuses 6 (5A), 8 (5A), 15 (5A), and 20 (5A)
  • Wiring harness
  • Loose or corroded connector(s)
  • Relays
  • Motors
  • Multifunction switch
  • Washer fluid level switch
  1. If the concern remains after the inspection, connect New Generation STAR (NGS) Tester to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the NGS menu. If NGS Tester does not communicate with the vehicle:
    • Check that the program card is properly installed.
    • Check the connections to the vehicle.
    • Check the ignition switch position.
  1. If NGS Tester still does not communicate with the vehicle, refer to the New Generation STAR Tester manual.
  1. Perform the DATA LINK DIAGNOSTIC TEST. If NGS Tester responds with:
    • CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to Section 418-00 .
    • NO RESPONSE/NOT EQUIPPED for generic electronic module (GEM), go to Pinpoint Test M.
    • SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and perform self-test diagnostics for the GEM.
  1. If the DTCs retrieved are related to the concern, go to GEM Diagnostic Trouble Code (DTC) Index to continue diagnostics.
  1. If no DTCs related to the concern are retrieved, proceed to Symptom Chart to continue diagnostics. Your best bet is take this to a ASE certified repair shop !

Hi:
If your truck has a wiper switch that you rotate counter clockwise to get the intermittent wipe mode, and turn clockwise to get to the low and high settings, then your truck has a interval wiper relay module. You could have a bad wiper switch assembly too, as the intermittent part of the switch is seperate from the low and high wiper switch. It is a inexpensive part, less than $20 for the switch, and the interval wiper relay part is somewhat expensive, 70-100 bucks or so. My truck didn't have intermittent wipers when I bought it, so I went to a junk yard and removed a switch and a module from a wrecked truck for $40, and it has worked fine ever since. Maybe you can find a good used part to swap into your truck for testing? Once you buy new electrical parts, you cant return them!

Principles of Operation
NOTE: The generic electronic module (GEM) will not activate the rear wiper system if either the liftgate or the liftgate glass is ajar. If either the liftgate or the liftgate glass becomes ajar while the rear wiper is in operation, the GEM will park the rear wiper motor.
There are two distinct modes of wiper operation:
  • Off Mode: In this mode, there is no rear wiper activity, and the wiper motor will be in the PARK position.
  • Interval Mode: This mode is selected when the rear wiper switch is in either the Interval 1 or 2 position. When this mode is selected, the rear wiper motor is driven up onto the glass by activating the rear wiper UP relay. When the wiper motor HIGH/LOW/PARK position input reaches the high position, the UP relay is deactivated and the DOWN relay is activated to reverse the wiper motor direction. When the wiper motor reaches the LOW position, as determined by the HIGH/LOW/PARK position input, the GEM deactivates the DOWN relay and will begin a new wiper cycle 1 to 10 seconds later, depending on the interval position selected.
To engage the rear window washer, rotate the rear window washer selector downward to the WASH position. The rear window wiper will run as long as the WASH position is selected. When the rear window washer selector returns to the OFF, INT 1 or INT 2 position, the washer will stop immediately, but the rear window wiper will continue for two to three sweeps and then return to its previous mode of operation.
The low washer fluid indicator chime warns that the washer fluid level is low. The low washer fluid indicator chime is a single tone with a duration of one second. The chime will sound when the low washer fluid indicator is initially activated.
The low washer fluid indicator warns that the fluid level in the washer reservoir is low. The low washer fluid indicator will illuminate when the washer fluid level is low and the ignition switch is in the RUN position.
The low washer fluid indicator will deactivate when the washer fluid reservoir is filled and the ignition switch has been cycled from RUN to OFF, then to RUN.
