Installation and Usage Notes
Safety First
Before starting any work, disconnect the vehicle's negative battery terminal and wait for at least 3 minutes to allow any residual power in the system (e.g., from airbag backup capacitors) to dissipate.
01
Removal Process
Carefully remove the steering column shrouds/trim covers to access the switch assembly. Note the routing of wiring. Depress the locking tabs to disconnect the electrical connectors from the old switch.
02
Installation
Align the new steering column switch (735374AP) correctly onto the steering column. Ensure all mounting points, clips, and screws are securely fastened. Reconnect all electrical connectors until they click into place.
03
Post-Installation Test
Reconnect the battery. Before reassembling all trim pieces, thoroughly test all functions: headlights (low and high beam), turn signals (left and right), hazard lights, front wipers (all speeds and intermittent settings), and windshield washers. Ensure no warning lights remain illuminated on the instrument cluster.
04
Packing, Storage, Handling & Transportation
Steering Column Switch 735374AP is individually packaged in a sealed anti-static bag placed inside a protective, form-fitting cardboard box. The product should be stored in its original packaging in a clean, dry, and temperate environment. Avoid exposure to direct sunlight, excessive moisture, or dust.
