Replacing Headlight Bulb 2001 Blazer LT

Can anyone tell me how to access the rear of the headlight housing for bulb replacement. My daughter purchased a vehicle without the manual. Any help would be greatly appreciated. Thanks, Revilo.

When you open the hood, you will see 2 plastic tabs on each side on the core support behind the headlights. Pull up on both tabs and remove. tip the headlights outward and remove. When reinstalling the headlights, make sure that the tabs on the light housing are in the slots on the core support. If you don't the light won't sit right.
