I OWN A 2002 CHEVROLET SILVERADO 2500HD WITH 8.1L ENGINE. THE TRUCK HAS STARTED STALLING (ENGINE COMPLETELY SHUTTING DOWN) WHILE I AM DRIVING AT DIFFERENT SPEEDS. THIS HAS HAPPENED AT LEAST 7 OR 8 TIMES NOW. THIS IS VERY DANGEROUS BECAUSE YOU NEVER KNOW WHEN IT IS GOING TO HAPPEN OR HOW FAST YOU MAY BE GOING. SO FAR, I HAVE REPLACED BATTERY, BATTERY CABLES, HAD THE FUEL LINES SERVICED, AND HAD THE FUEL INJECTORS CLEANED. AFTER DOING A LITTLE RESEARCH, IT APPEARS THAT THE CRANKSHAFT POSITION SENSOR IS THE ISSUE AS IS ON MANY OF THESE TRUCKS. THERE WAS A RECALL ON THE 2001 TRUCKS FOR THIS ISSUE BUT NOT ON THE 2002 TRUCKS FOR SOME REASON. COSTLY TO FIX THIS ISSUE. MY TRUCK ONLY HAS 67,000 MILES ON IT. *TR

BLOWER MOTOR STOPPED WORKING LAST YEAR. I HAD A NEW BLOWER MOTOR INSTALLED AND THE REPLACEMENT STOPPED WORKING. WHEN I BROUGHT MY TRUCK TO BE REPAIRED FOR THE SECOND TIME, I WAS INFORMED THAT THERE IS A PROBLEM WITH THE WIRING/RESISTOR WHICH SUPPLIES POWER TO THE BLOWER MOTOR. APPARENTLY, THE MOTOR PULLS MORE POWER THAN THE WIRING IS RATED FOR WHICH CAUSES IT TO HEAT UP AND BURN THE INSULATION OFF OF THE WIRING UNDER THE DASHBOARD. MY MECHANIC TOLD ME THAT I SHOULD CONSIDER MYSELF LUCKY THAT MY TRUCK DID NOT CATCH FIRE LIKE ANOTHER CUSTOMER'S TRUCK HE HAD RECENTLY REPAIRED FOR THE SAME REASON AS MINE HAD. I FEEL THAT I HAVE PAID FOR REPAIRS TWICE DUE TO DEFECTIVE GM PARTS. *TR
