Open up the trunk lid, find the Phillips screws above the tail lights and the whole tail light bucket will pull out as one piece. Light sockets are behind.

I have a 93 Caprice and the cruise went out a few times. Check the third brake light in the back of the window. If it is out replace it and this might fix the problem. Also check the fuse as it controls the cruise and third brake light as well.
If there is no light at all in whole dash. first check the fuse second check the headlight control switch.
brake light plunger switch on the brake pedal maybe faulty, remove it and connect the two wires together and pull apart and see if lights go on and off
Slightly different front end with european-style headlights on the '88, slightly revised taillights, different dashboard, 3rd brake light on the '88 - that's about it.
