Chevrolet 1995 Tahoe Owner's Manual page 130

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.
Add one peg at a time
until the PUSH button
on the compartment
door operates the
garage door opener,
with the compartment
door closed, when you
push the button
marked PUSH.
With the garage door opener positioned properly and the right number of
pegs in place, you should only have to push the PUSH 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.
