What is the stalk switch?
What is the stalk switch?
This automatically switches the indicators off after you have turned into a bend. Indicator stalks are usually trouble-free but, like everything else, they can develop problems. In addition, the stalk often controls other items like headlight dip/main beam and flash, and the horn .
What does the wiper switch on the steering column do?
The wiper switch on the steering column (multifunction switch) commands the control module and the control module operates the wiper motor through wiper motor relays, see the diagram. There could be up to 3 relays: one for the wiper motor high speed circuit, one the for low-speed circuit and one for…
How does the intermittent wiper relay work in a car?
The relay functions as a switch and energizes circuits as needed. In the case of your windshield wipers, it controls low, high, and intermittent speeds by energizing a particular circuit at a given moment depending on what speed you have your wiper switch set to. Secondly, what happens when a wiper relay goes bad?
Where is the park position on a wiper motor?
This position is called “park position.” Wiper relays can be installed in the fuse box under the hood or in other location. In some cars a wiper relay is built inside the Body Control Module (BCM). It’s not uncommon for a wiper relay to fail or stick, causing the wiper motor not to work or work with the switch turned off.
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.
How does the intermittent wiper relay system work?
This operation is completed thanks to the intermittent wiper relay; an electrical switch that sends a predetermined setting to the wiper module to power the wiper motor. When all of the components involved in the windshield wiper blades work correctly, the system is very convenient.
What happens when a windshield wiper relay goes bad?
When the relay is faulty, the windshield wipers will only work at the same speed that the last relay signal was sent. In layman’s terms, if you had your windshield wipers on the slow speed the last time they were active, and you turn them on again under a different setting, the relay switch should send that updated information to the module.
Why is my wiper blade motor not working?
Similar to the issue above, if you notice that your wiper blades are operating at a different speed or intermittent setting than you selected, it’s a good indication that the relay is damaged and needs to be replaced. This is also a symptom that you don’t want to avoid as it may cause the wiper blade motor to overheat and break prematurely.
