Turn signal does not work at all time, but hazards lights work

I have the same problem, occasionally the door bonging sound bongs for each click and makes driving very painful to the ears. I have attempted to fix this problem; I replaced the hazard switch, however, this did not solve the problem. I have been recommended to replace the multi-function switch, the switch that contains the two control arms on the sides of the steering wheel. I will try this next, I think the part is ~$200. Hopefully that will solve the problem.

where is the signal flasher located?

On the 2002 Chevrolet Malibu the turn signal flasher is part of the hazard switch.
