Hello,

 

This should help you out. They might be out of order a bit.

 

 

Removal & Installation

  1. Disconnect the negative battery cable.

  2. From under the headlight switch assembly, remove the trim plate/switch assembly retaining screws.

For some vehicles equipped with fog lamps, the lamp switch may have to be removed in order to access the headlight trim plate/switch screw.

  1. Pull the switch trim plate from the instrument panel. On late model vehicles, pivot the trim plate outward at the bottom, then pull the plate downward to release it.

  2. Disengage the electrical wiring connectors from the rear of the trim plate/switch assembly.

  3. Remove the headlight switch from the trim plate;

 

To install:

  1. Install the new switch to the trim plate.

  2. Engage the electrical wiring connectors to the rear of the switch/trim plate assembly.

  3. On late model vehicles, pivot the trim plate inward at the bottom, align the switch trim plate, then connect it to the instrument panel.

  4. Install the trim plate/switch retaining screws and secure them under the headlight switch assembly.

  5. If equipped, install the fog lamp switch.

  6. Connect the negative battery cable.

  1. Disconnect battery ground cable.

  2. Reaching up behind instrument cluster, depress shaft retaining button and remove switch knob and rod.

  3. Remove instrument cluster bezel screws on left end. Pull out on bezel and hold switch nut with a wrench.

  4. Disconnect multiple wiring connectors at switch terminals.

  5. Remove switch by rotating while holding switch nut.

Hi,

 

 

Ok, that type you have to first remove the push/pull knob by reaching up under the dash and with the knob pulled out, depress that little silver tab on the switch and remove the knob,then you need a large screwdriver and remove the nut in the center that was behind the knob stem. Once that nut is off, the switch pulls out from the back. It's tough because there isnt much room under the dash to work with.
