2004 Chevrolet Impala 3. 4l v6, 70,000 miles. Right turn signal intermittent failure started occurring at around 65,000 miles - interior dash turn signal indicator blinks rapidly but the actual turn signal does not flash at all. I checked all lamps and fuses then replaced the hazard switch as suggested by some car forums but the problem remains!.
