Dimmer Switch Adjustment
- With switch removed from column bracket, insert a 3/32" drill bit into adjusting pin hole to limit switch travel. See Fig 1
. Insert actuator rod into switch. Install switch to column bracket, but only finger-tighten screws.
- Lightly push switch upward against actuator rod until no lash (free-play) exists between rod and switch. Tighten mounting screws to 35 INCH lbs. (4 N.m). Remove drill bit. Ensure proper switch operation using dimmer/headlight switch handle.
