Hazard switch - turn signals not working / intermittent.
Turn signal malfunction involving flickering of turn signal at random. I will be driving and hear the flasher go off erratically. No consequences except a lot of annoyance from the sound and having to replace the flasher myself. Will save old part.
2002 Oldsmobile Alero. At 57,000 miles turn signals are occasionally inoperative. Fuses were changed and they still fail on occasion. Identical problems resulted in the recalls of the 2000 and 2001 olds Aleros. Upon reviewing internet web sites I discovered that there are many other Alero owners whom are having the same problem. A temporary solution until the hazard switch can be replaced is to slap the dashboard near the hazard switch to make it operable. The inability to alert other drivers of the intent to change lanes, or make turns is a safety issue.
Turn signals and flasher work only once in awhile all of a sudden.
