Wiper Switch

Service of the wiper switch requires first disconnecting the cable from the negative battery terminal and waiting 90 seconds to avoid Air Bag and seat belt pretensioner activation. After steering column cover removal and windshield wiper switch assembly separation from the connector by cutting off its claw apply minimal force since hard pressure might cause claw destruction. Follow the installation steps by engaging the claw to the windshield wiper switch and then connect the connector before reinstalling the steering column cover. The connection of the negative battery terminal should conclude by performing initialization procedures since some systems require this step after cable disconnection and connection.

When servicing the wiper switch the first step is disconnecting the cable from the negative battery terminal while waiting at least 90 seconds to avoid triggering Air Bag and seat belt pretensioner activation. Severing connections from the column cover requires you to detach the claw security before installation while avoiding excessive claw tension as this might damage the components. The claw attachment should secure the windshield wiper switch before reconnecting the connector followed by reinstalling the steering column cover. Apply initialization during the process before resuming connection of the cable to the negative battery terminal since some systems must perform this after battery cable removal and reinstallation.
