2006 TRAILBLAZER 4WD. THE DRIVER'S SIDE WINDOW BECOME ERRATIC DURING OPERATION AT FIRST. THEN ENTIRE ELECTRICAL SYSTEM WAS AFFECTED OVER NEXT DAY OR TWO, INCLUDING MAKING DOOR LOCKS OPERATE ON THEIR OWN, HEARD ELECTRICAL CRACKLING SOUNDS IN DOOR AND DASHBOARD. SMELLED ELECTRICAL FIRE FUMES SLIGHTLY ONCE. ENGINE WARNING LIGHT CAME ON, FOLLOWED BY LIGHT WARNING THAT STABILATRAK HAD ISSUES. TOOK IT INTO CHEVROLET DEALERSHIP (HARBOR, 9911 W 300 N, MICHIGAN CITY, IN. PHONE (219) 210-4266.) AFTER THE SERVICE DEPARTMENT INVESTIGATED, THEY REPORTED THAT THE ISSUE WAS A BURNED OUT DRIVERS DOOR MODULE THAT HAD OBVIOUS CHARRING ON IT. THE SERVICE TECH NOTED ON INVOICE SHEET THAT HE FOUND THE ENGINE LIGHT WAS INDICATING A P0171 DIAGNOSTIC ISSUE WHICH HE TRACED TO THE "FAILED/SHORTED" DRIVER DOOR MODULE. THE SOLUTION WAS TO REPLACE THE MODULE AND PROGRAM THE NEW MODULE. THE NEXT DAY AFTER GETTING BACK THE VEHICLE, THE ENGINE WARNING LIGHT CAME ON AGAIN. A CHECK BY ME USING MY OBD UNIT SHOWS THAT ONCE AGAIN THE P0107 IS THE ISSUE. I HAVE ALSO AGAIN HEARD CRACKLING IN THE DOOR, BUT NO ELECTRICAL ISSUES SEEN THUS FAR. WILL BE HEADING BACK TO DEALERSHIP FIRST CHANCE THAT I GET. COST OF THE UNIT REPLACEMENT WAS $524.62. *TR
