This is a complex wiper system . Here are all the components involved !
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


Circuit/System Description
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 windshield wiper motor park operation is controlled by the BCM. The BCM recieves an input from the park switch to determine wiper blade position. When the wiper blades are at the bottom of the windshield glass in park position the wiper park switch will open and the circuit will be pulled up to B+ by the BCM. The park signal will be pulled to ground by the wiper motor park switch while the wiper blades are not in the park position.
The BCM controls the windshield wiper motor through two output controls, controlling two relays which determine the desired wiper speed, high or low
Diagnostic Trouble Codes (DTCs)
The body control module (BCM) monitors the voltage on the windshield wiper switch signal 2 circuit for diagnostic purposes. If the circuit is shorted to voltage while the driver is commanded OFF, the BCM will store DTC B3715. If the circuit is shorted to ground while the driver is commanded ON, the BCM will store DTC B3715. Refer to DTC B3715.
It would be best to have a factory scan tool to diagnose this problem . it would make it easier anyway .

Wiper dont work


Check all your fuses and breakers first. With the ignition turned to run check that you have power at the WCM, wiper control module, check the multifunction switch the wipers run off of, check wiper motor or linkage under the plastic cowling under the wiper blades, comes off easily with a few screws and clips.

Is there a procedure to check the wiper motor on 1991 S10 pickup (only 42000 miles), to be sure it is defective and not a wiring problem?


ONLY PROCEDURE FOR WIPER MOTOR IS YOU HAVE 2 SPEEDS THAT WORK SLOW AND FAST SPEED.WIPERS WILL RETRACT TO THE BOTTOM OF HOOD LINE WHEN YOU TURN OFF. WIPERS SHOULD TURN OFF. CHECK WIPER RESERVOIR MAKE SURE ITS FULL AND WIPER WASHER SPRAY FLUID CLEAN WINDSHIELD. IF WIPER MOTOR DO ALL THE ABOVE THEN ITS OKAY.IF WIPER MOTOR WORKS SLOW LOOK FOR BINDING AT WIPER ARM LINKAGE AND PIVOT LUBRICATE LINKAGE AND PIVOT COULD HELP.IF WIPER MOTOR DONT WORK CHECK FOR POOR GROUND OR BLOWED FUSE.WIPER WORK AT ONE SPEED CONTROL SWITCH IS BAD.IF WIPER BLADES STOP WHERE EVER THEY ARE OR FAIL TO TURN OFF UNLESS YOU TURN OFF IGNITION SWITCH WIPER MOTOR LIMIT SWITCH BROKEN.IF WIPERS DONT RETRACT BELOW BOTTOM HOOD LINE LOOK FOR MECHANICAL OBSTRUCTION OR WIPER MOTOR FAULTY.

The fuse could be blown, or the motor could be bad, or the switch may be bad, or the wiring in between.
