Chevrolet Repair: brake lights, brake light switch, 1990 chevy 1500

Question
I just bought a 1990 chevy 1500 2wd and the headlights and everything work but the brake lights don't come on at all when I push the brakes.

Answer
HI CHARLES,LETS TRY THE EASY THING FIRST AND CHECK ALL THE FUSES.IF ALL OF THOSE CHECK OUT MAKE SURE THAT ALL THE BULBS ARE OK.IT SEEMS UNLIKELY BUT I HAVE SEEN ALL THE BULBS BEING BURNED OUT AT THE SAME TIME.IF THE BULBS ARE OK IT IS TIME TO CHECK THE BRAKE LIGHT SWITCH WITH A TESTER.
