Hello
I have provided lots of information for you. Probably more than you wanted. But this gives you the information you need.
My suggestion is I would first check the two fuses, fuse 3 and 26. Use an Ohm meter as they may look good but may not be. This is located under the dash it looks like.
Then I would check out the switch
I would then check out the motor
Last I would check out the control unit.
I think it is your switch. But see if this checks out and let us know.
General Information on Wiper Operation
When the ignition switch is in ON (II) or START (III), battery voltage is applied to the combination wiper switch, and the windshield wiper motor.
Low Speed
When you turn the wiper switch to LO, the wiper motor's low speed winding is grounded through the BLU wire and the LO speed contacts of the wiper switch at G401, and the wipers run at low speed.
Park/Off
When you turn the wiper switch OFF , the integrated control unit (PARK input) grounds the wiper motor through the BLU/WHT wire. The cam switch on the motor signals the integrated control unit that the wipers are in the PARK position: the control unit then removes ground from the motor, and the wipers stop in the PARK position.
High Speed
When the wiper switch is in HI, the high speed windings of the windshield wiper motor are grounded through the BLU/YEL wire and the HI contacts of the wiper switch at G401, and the wipers run at high speed.
Intermittent
When the wiper switch is in INT, battery voltage is applied through the YEL/BLU wire to the Integrated Control Unit (Intermittent wiper ON input). The integrated control unit (Intermittent/Park Wiper Control) grounds the low speed windings of the wiper motor and the wipers make a single sweep every few seconds (See Low Speed). When the wiper returns to the PARK position, the park switch applies battery voltage through the BLU/WHT wire to the integrated control unit (PARK input), and the wipers stop in the PARK position.
Mist
When you pull the wiper switch down to MIST position, the high speed windings of the wiper motor are grounded through the BLU/YEL wire and the closed contacts of the mist switch at G401, and the wipers make one pass across the windshield at high speed. The Park/Off function then takes over and the wipers stop in the PARK position.
Washer
When you pull the wiper switch toward you to turn on the washer switch, battery voltage is applied to the washer motor. The motor pumps fluid onto the windshield until you release the lever; on '98-'99 models, the integrated control unit (windshield washer ON input) senses power at the WHT/BLK wire terminal and runs the wipers whenever the washer motor runs.
Wiper Switch Check Out
Remove the driver's dashboard lower cover.
Remove the steering column covers.
Disconnect the 8P and 6P connectors from the switch, remove the two screws, and pull out the switch.
Check for continuity between the terminals in each switch position according to the table
Integrated Control Unit Input Test
SRS components are located in this area. Review the SRS component locations, precautions, and procedures before performing repairs or service.
Remove the driver's dashboard lower cover and knee bolster.
Disconnect the 10P connector from the integrated control unit.
Remove the integrated control unit from the under-dash fuse/relay box.
Inspect the connector and socket terminals to be sure they are all making good contact.
If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
If the terminals look OK, make the following input tests at the connector and the fuse/relay box socket.
If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, the control unit must be faulty; replace it.
All Systems:
Intermittent Wiper System:
Key-in/Seat Belt Reminder, Lights-on Reminder System
Bulb Check System (Brake System Light):
Wiper Motor Check Out
Open the hood, and remove the cap nuts. Carefully remove the wiper arms so that they do not touch the hood.
Remove the cowl cover by prying out the trim clips.
Disconnect the 5P connector from the windshield wiper motor.
Test the motor by connecting battery power and ground according to the table. If the motor does not run or fails to run smoothly, replace it.
Connect an analog voltmeter between the No.5 (+) and No.3 (-) terminals, and run the motor at low or high speed. The voltmeter should indicate 0 V and 4 V or less alternately.
