2004 chevy Impala--both turn signals and hazard lights stop flashing. Tried to replace fuses, but all still good. Could not locate a turn signal relay in the fuse box. Spoke to a mechanic who said it didn't make since that there was no relay in the fuse panel. Looked up the turn signal switch part and it was on back order. The part alone was over $300. 00. Mechanic also stated it did not make since that it would be the turn signal switch when all other components on the turn signal arm (windshield wipers, cruise control, etc. ) still worked. Unable to go to the dealership since it was a Sunday. Looked up other similar complaints on topix. Com and found several people having the same problem. Was advised to turn on and off the hazard several times. In doing so (about 100 times) the signals started working. Therefore, it doesn't seem as if this is a turn signal switch issue, but a hazard switch issue. This is a very dangerous situation if driving and your turn signals stop working which could cause a serious accident.
