• Q: How to replace the headlamp dimmer switch assembly on 2005 Toyota Tacoma?

  A: Begin the headlamp dimmer switch assembly replacement process by following Air Bag system precautions then disconnecting the negative cable from the battery for at least 90 seconds to avoid Air Bag activation. Use Special Service Tool: 09950-50013 (09951-05010, 09952-05010, 09953-05020, 09954-05021) to remove steering wheel assembly and its components comprising horn button assembly, steering wheel cover lower No.2, steering wheel cover lower No.3 and steering wheel assembly from their positions with front wheels positioned forward. The installer needs to disconnect the windshield wiper switch assembly after removing the steering column cover lower and steering column cover upper and spiral cable sub-assembly before extracting the headlamp dimmer switch assembly. The new headlamp dimmer switch assembly should be connected through the 2 claws before securing with the clamp then connecting the connector. Follow this replacement order to install the windshield wiper switch assembly before the spiral cable sub-assembly along with the steering column cover upper and the steering column cover lower while paying attention to spiral cable positioning. Continue the installation by putting back the steering wheel assembly and examining the horn button and steering wheel center point assembly before installing the horn button. To finish the procedure connect the cable to the negative battery terminal applying 3.9 N.m of torque and verify the SRS warning light operation followed by reinstallation of steering wheel cover lower No.3 and lower No.2.
