You don't want to ruin the glove compartment! Try every code possible until it opens.
"using a flashlight peer into the number wheels while turning them. When you come across a slot in the left side of the wheel that is one combination for that wheel. Do the same for the other 2 wheels and the glove box will open.
Note these slots are located at the center of the wheels axis
PS the default setting from the factory was 000"
