Chevrolet Repair: 2000 Chevy Extended Cab, turn signal switch, brake light switch

Question
Replaced Brake Light Swtich and Brake Lights Still Dont Work,Replaced all bulbs and checked fusses

Answer
HI BARRY,,GET A TEST LIGHT AND CK FOR POWER AT THE BRAKE SWITCH. IF POWER IS THERE GO BACK TO THE REAR OF THE TRUCK AND FOLLOW THE WIRING HARNESS FROM THE BRAKE LIGHT SOCKET DOWN UNDER THE REAR BUMPER TO FRAME AREA AND YOU SHOULD SEE A HARNESS PLUG. JUMP THE BRAKE LIGHT SWITCH OR PUSH DOWN ON THE BRAKE PEDAL AND THEN CK FOR POWER AT THIS PLUG HARNESS BY THE FRAME ONCE YOU OPEN UP THE HARNESS CONNECTION.. CK THE COLOR OF WIRE FROM THE LIGHT SOCKET AND IT SHOUD BE THE SAME AT THE HARNESS PLUG. IF THERE IS POWER HERE THEN YOU HAVE A BREAK IN THE HARNESS SOMEWHERE FROM THIS POINT BACK TO THE LIGHTS.  IF NO POWER TO THIS POINT CK ALONG THE FRAME RAIL AND INTO THE CAB FOR A BREAK IN THE WIRING OR CONNECTION FAILURE..DOES THIS TRUCK HAVE A TRAILER HOOK UP..IF SO, CK THE WIRING VERY CLOSE AT THIS POINT.. I HAVE FOUND MANY MANY PROBLEMS WHERE THEY HOOKED UP THE WIRING TO THIS PLUG CONNECTION...NOW LETS SAY WHEN YOU CK FOR POWER AT THE BRAKE LIGHT SWITCH AND YOU FIND THERE IS NO POWER THEN MORE THEN LIKELY YOU HAVE A FAULTY TURN SIGNAL SWITCH IN THE COLUMN..[VERY RARE ]HOPE THIS HELPS YOU AND LET ME KNOW HOW YOU MAKE OUT,,,TOM..
