Question about 1994 GMC Suburban

2 Answers

94 Suburban My windshield wipers do not operate as they should: stop mid-cycle, do not stop when wipers turned off, will not dispense washing solution sometimes. The post on FixYa regarding the circuit board looks like it will solve much of the problem by either repairing or replacing the board. Question: will repairing or replacing the board address the problem of dispensing the washing solution? Any help much appreciated !!!

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 .

Why is my windshield wipers running in the off position, it's like they are running in the intermittent position, but it's in the off position.


When the windshield wiper / washer switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the wiper motor module will continue to operate the wiper 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. The wipers will park the next time the ignition is cycled to the ON position.

2007 Pontiac g6 wipers stay in upright position


Hey Derek , here is how the wipers park position is suppose to work !
Windshield wiper motor park operation is controlled by the body control module (BCM) using an input from the park switch within the wiper motor assembly. The BCM monitors the windshield wiper motor park switch circuit to determine if the windshield wiper blades are at the bottom of the glass. The circuit will be pulled to ground by the wiper motor park switch while the windshield wiper motor is operating. 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. The BCM will park the wipers the next time the ignition is turned ON.
The wipers will not park when they are commanded ON and OFF with a scan tool. The BCM will park the wipers the next time the wiper switch is turned ON and OFF.
The BCM provides stall protection for the wiper motor by monitoring the park switch. If the park switch does not transition for 3 seconds while the wipers are operating, the BCM will assume that the wiper motor is stalled, and will de-energize the wiper relay until the wiper switch is cycled OFF and ON again.
Check for a voltage signal on the yellow wire at the wiper motor assembly , this is signal to the BCM ! If there is no signal you need to replace the windshield wiper motor assembly ? If there is a signal need to have Tech 2 scan tool hooked up to see if The BCM is the problem ! Relay #39 an #40 are the high an low wiper relays in the under hood fuse block ! Do you have a volt meter ,do you know how to do electrical testing ?

2000 HYUNDAI ACCENT, problem is the Windshield Wiper operation is malfunctioning, in the Delay mode, and in the off position, Windshield Wiper arms/blades stop at the half point on the Windshield glas


The park position is controlled inside the motor/actuator assembly. Not sure if it can be repaired. See if it is assembled with screws versus rivets. A new assembly is less than $100.

When I turn the windshield wipers off in mid cycle-they don't go all the way down. they stop half way down the windshield. do you think the motor is bad? Also, rear windshield wiper does not work at...


yes the wiper motor is probably at fault due to the self parking mechanism is internally in the motor.
well the rear one check fuses and then check for power at motor, if there is power at motor possibly motor again, if there is no power at motor when operating check wiring in flexible joint between body of car and back door/tailgate.

  • 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.
