Center the garage door opener activation button over
the console door button and press the opener firmly
into place.
Add one peg at a time until the garage door opener
operates with the compartment door closed when you
press the button.
The pegs inside the
compartment door are used
to make sure the button on
the compartment door will
contact the control button
on the garage door opener.
With the garage door opener positioned properly and the
right number of pegs in place, you should only have to
press the button slightly to operate the opener. Adjust
the position of the garage door opener and add or
remove pegs, as needed, until the opener operates
properly.
Now, with the compartment
door closed, press the
button again to make sure
the garage door opener
operates properly.
