Hello my name is XXXXX XXXXX will be more than happy to assist you.
Most likely the wiper motor/module is bad pretty common, but with out doing a electrical test at the motor/module to verify it I can't rule out the wiper motor switch.
If you have or have access to a volt meter I can assist you with how to test it and verify if it is the wiper motor/module or the switch and also give you instructions on how to replace either part.
The only thing I did not think of is to test it you will have to remove both windsheld wiper arms and the cowl that covers the wiper motor.
The wiper arms are a pain to get off some times. The cowl is easy once the wiper arms are off.
You you want me to send you instructions on how to take the wiper arms and cowl off?
Once you have both off you can disconnect the connector to the wiper motor.
Connect the black wire on the volt meter to ground (battery negative or non painted metal part)
-Now turn the vehicle on (not running)
-Turn on the wiper motor to the highest setting.
- Take the red wire on the volt meter and touched to slot (D see diagram below) the volt meter should show about 12 volts
Now take the red wire and move it to slot (E) and turn with wiper motor switch to the setting that did not work. If you have voltage then the wiper motor is bad.
To be on the safe side don't accept at this time, wait until the problem is found.
