Wiper Switch

The first step for windshield wiper switch assembly replacement requires disconnecting the battery cable from the negative terminal then waiting 90 seconds before the Air Bag deploys. After disconnecting the cable from the negative battery terminal let it be for at least 90 seconds and remove both the lower and upper steering column covers. Separate the two connectors from the windshield wiper switch assembly while using a screwdriver with tape on it to release the claw. Remove the assembly at a gentle touch to protect the claw from breaking. The new windshield wiper switch assembly needs installation by connecting its two connectors after engaging the claw. Reattach the cable to the negative battery terminal while tightening it to a torque of 3.9 N.m (40 kgf.cm, 35 in.lbf) before replacing the steering column covers in their proper positions.

Wiper switch servicing requires first disconnecting the negative battery terminal cable then waiting for 90 seconds minimum to stop the Air Bag safety deployment. Begin by separating the wiper switch from its position by disconnecting the 2 connectors and using a screwdriver with protective tape to carefully disengage the claw. This operation must be performed with gentleness to prevent breaking the claw structure. Install the windshield wiper switch assembly through the claw mechanism before connecting its two connectors. The cable installation to the negative battery terminal should be executed with a torque setting of 3.9 N.m (40 kgf.cm, 35 in.lbf) while the process ends with replacement of the steering column upper cover and the steering column lower cover.

Service of the wiper switch begins by eliminating the lower steering column cover using the proper procedure for manual tilt and telescopic controllers and power tilt and telescopic controllers. A shifting of the steering wheel to both right and left sides enables screw removal and claw disengagement to detach the lower steering column cover maintaining safety of the tilt and telescopic switch. The next procedure involves removing the upper steering column cover after dismantling both clips and the claw connecting points. Unplug both connectors from the windshield wiper switch assembly before you detach the claw by avoiding strong force against any parts. You need to attach the claw to position the wiper switch before rejoining both connectors. You should attach the 4 clips and claw for the upper steering column cover while also installing the lower column cover by connecting the 2 claws with a screwdriver to secure the 2 screws when steering the wheel from right to left without harming the tilt or telescopic switch.

Engage the claw and install the windshield wiper switch assembly, reconnect the 2 connectors, and then connect the cable to the negative battery terminal with a torque of 3.9 N.m (40 kgf.cm, 35 in.lbf).

Remove the steering column lower cover and then the steering column upper cover.

Disconnect the 2 connectors from the windshield wiper switch assembly.
