I WAS RETURNING FROM LAS VEGAS ON A RUFF PAVED DESERT HWY IN MY 2005 5 SPEED 2 DOOR CHEVY BLAZER WHEN I NOTICE A SLIGHT SMELL OF ELECTRICAL SMOKE. I TURNED ON THE DOME LIGHT AND NOTICE THE TURNING SIGNAL SWITCH ARM BOUNCING A LOT WITH SOME SMOKE COMING OUT THERE AT THE COLUMN ! I SLOWED FROM 65 TO 40 WITH MY FLASHERS ON, PROBLEM SOLVED . GOT BACK ON A SMOOTH FREE WAY AT 65 WITH NO SMOKE. THE SWITCH ARM GOT SLOPPIER OVER TIME BUT STILL WORKED FOR ABOUT SIX MONTHS. THEN ONE DAY I TURN RIGHT WITH MY SIGNAL ON, WINDSHIELD WIPERS CAME ON BY THEMSELVES, & THE SMOKE WAS BACK (MUCH STRONGER ) WHILE DRIVING SLOW! I THEN PULLED INTO A AUTO PARTS PARKING LOT, SHUT IT OFF, & TOOK OUT THE KEYS! TO MY SHOCK THE WIPERS, & SMOKE KEPT GOING! I THEN OPENED THE HOOD, UNPLUGGED THE WIPER MOTOR, & AGAIN PROBLEM SOLVED ! THEN CAME A RAINY DAY SO I HAD TO PLUG BACK IN THE WIPERS, THINGS STILL ALL OK! BUT THEN I MADE A RIGHT TURN WITH THE TURN SIGNAL ON! THE EVEN STRONGER SMOKE WAS BACK PLUS MY ASTHMA ATTACK (USED MY INHALER ) ! I THOUGHT ABOUT STOPPING IN THE STRONG RAIN BUT I TURNED ON THE A/C ON FULL THEN GOT VERY MAD ! I YANKED ON THE PLASTIC SWITCH ARM PULLING IT TO THE LEFT, & IT POPPED OFF IN MY HAND! PROBLEM SOLVED EXCEPT NOW MY WINDSHIELD SPRAY, & WIPER DELAY DON'T WORK! I STILL GET SOME SMOKE ON RUFF ROADS! THE WHOLE TURNING SIGNAL WITCH PART COST $599.95 AT CHEVY PLUS $330.00 LABOR ! TO RICH FOR ME! I TOOK THE SMALL COLUMN DASHBOARD PANEL OFF, PUT A KILL SWITCH ON THE WIPER MOTOR POW
