Windshield Wiper Switch Replacement Cost Estimate

When the windshield wiper will not do one or more functions on demand, the switch will likely be tested first. The switch can be diagnosed as faulty simply by testing for continuity across the switch when the switch is cycled through all of its possible settings. If pressing the switch does not create a continuous circuit,the switch will be proven failed.

For some vehicles, replacing the windshield wiper switch may involve simply removing the steering column cover or trim, disconnecting the electrical connector, and releasing the switch from the steering column by removing fasteners and mounting brackets. Other models will require all of this, but also the air bag, steering wheel, and clock spring (AIR coil) will need to be removed as well. It is important to note that the battery will be disconnected prior to servicing these components.

Checking your fuses first is always recommended when it comes to electronics. All too often an electrical component is replaced only to find it still does not function. This is because without a good fuse, the system will not receive power.

When servicing the steering column, be aware that the airbag (SRS system) wiring harness runs along the steering column as well. Disturbing the air bag and harness without proper knowledge may cause SRS system faults, unintentional airbag deployment, or physical harm as a result.

If the windshield wiper switch being replaced does not require removing the airbag and steering wheel, this repair can be accomplished by most people. However, when airbag and steering wheel removal are necessary, it is not recommended unless proper precautions are taken and the repair is completely understood. In most cases, it is best to leave airbag removal to a professional technician.
