Answer
HI MIKE. I ANSWERED THIS QUESTION THIS AM BUT YOU MUST NOT OF GOT IT ???? I WILL ASSUME YOU MEAN THAT THE BLOWER MOTOR STOPS.  CK THE WIRING ON TO THE BLOWER MOTOR UNDER DASH. I HAVE SEEN ALOT OF THESE PLUGS BURN UP..THE BLOWER MOTOR RESISTOR WOULD NOT CAUSE THE BLOWER TO STOP ONLY ON LOWER SPEEDS. WOULD STILL WORK ON [HIGH SPEED ONLY]. WHEN THIS HAPPENS CK FOR POWER ON THE BIG PURPLE WIRE GOING TO THE BLOWER MOTOR. IF THERE IS POWER THERE,THEN MORE THEN LIKELY THE MOTOR IS BAD. CK THE GROUND MAKE SURE THAT IS OK AS WELL. IF THERE IS NO POWER TO THE MOTOR WIRNG OR THE SWITCH IS BAD... HOPE THIS HELPS TOM..
