1994 GMC SUBURBAN. WHEN BRAKE LIGHT SWITCH FAILS, THE CRUISE CONTROL WILL NOT BE SHUTOFF BY HITTING BRAKES. IF SWITCH FAILS, HITTING BRAKES WILL SLOW VECHILE, BUT CRUISE CONTROL WILL GIVE IT MORE GAS. DATE OF INITIAL ACCIDENT IS APPROXIMATE SINCE I DO NOT HAVE PAPERS WITH ME. SWITCH HAS FAILED TWICE SINCE THAT AND WAS FAILED AFTER THE ACCIDENT.

Waverly, GAFire
ELECTRICAL SYSTEM:WIRING:INTERIOR/UNDER DASH
FRONT WIPER MOTOR STALLED DURING RAINSTORM, TRAVELLING 55MPH ON MAJOR HIGHWAY. WIPER AND WIPER FLUID MOTOR QUIT UNEXPECTEDLY WHILE IN OPERATION OR WHILE STOPPED. SOMETIMES A BUZZING SOUND OCCURS WITH THE FAILURE. I DISCOVERED THAT I CAN TAP THE WIPER MOTOR MODULE AND THE WIPER MOTOR MAY BEGIN AGAIN, BUT ITS WORK WILL BE SHORTLIVED. ANOTHER PROBLEM I ENCOUNTERED WITH THIS VEHICLE WAS A MELTDOWN AND SMALL FIRE UNDER THE DRIVERSIDE DASH. THE ROCKER SWITCH THAT CONTROLS THE DOME LIGHT HAS AN "AUTO" AND AN "OFF" POSITION. WHILE IN "AUTO" FOR ABOUT 1 HOUR WITH THE DOORS OPEN, I NOTICED SMOKE COMING FROM UNDERNEATH THE DASH AND THE ROCKER SWITCH HAD MELTED DOWN DUE TO EXCESSIVE HEAT BUILDING UP IN THE CONTACT. I CONTACTED THE LOCAL DEALER WHEN I PURCHASED A REPLACEMENT SWITCH WHO COMMENTED THAT THESE SWITCHES WERE A PROBLEM.
