How does the front wiper motor and linkage work?
The front wiper motor and the wiper transmission mechanism (linkage) are installed below the windshield inside the cowl panel. How the wiper system works: the wiper switch sends the signal to the control module. The control module operates the wiper relay that sends 12-volt power to the wiper motor.
Why does my wiper stop in the wrong position?
Both wipers work, but stop in the wrong position This can happen for a number of reasons. Sometimes the little motor arm that is connected to the wiper motor gets loose and shifts on the motor shaft, causing it not to stop in the correct Park position (see the diagram above).

Why does my windshield wiper motor not work?
Problems with a multifunction switch can cause the wiper motor to work in some modes, but not to work in others. For example, in some Ford trucks, a bad multifunction switch was known to cause the wipers to operate in the low/intermittent mode even after the switch is turned off. Working windshield wipers are important for safe driving.
How can you tell if your windshield wiper linkage is broken?
The way to tell if it’s a motor or linkage issue is if you hear the motor working, but don’t see the wiper blades moving – it’s the wiper linkage that is broken. This may also be attributed to the wiper arm being stripped from the linkage. In either case, it’s important to have this problem fixed as quickly as possible by a certified mechanic.
What causes the wiper blades to move out of sequence?
When the blades move out of this sequence, it is typically due to the linkage being worn out or that the windshield wiper arm is loose. Sometimes it’s a minor issue like a loose nut that attaches the wiper arm to the linkage and in other cases it means the linkage is stripped.
How do you adjust the park position on a wiper?
Use a socket wrench to remove the nut located at the center of the wiper motor. This nut connects the arm linkage to the motor. Turn the wipers on, then back off, so the motor completes a full cycle and returns to the correct park position.
What to do if your wiper arm is out of linkage?
First, wipers start moving slower, then seize up completely. If it’s possible to free wiper arm shafts out of the linkage, your mechanic may suggest an option to clean and lubricate the shafts without replacing parts. That is cheaper, but the proper solution is to replace the linkage.
