It's easy. There are a couple of screws on the underside of the gauge cluster to remove, and then the gauge cluster is loose. The hazard switch can be gently pried ot using a small screwdiver. Very easy.
in almost any car in the middle of the control place or the sign with red triangles
Welcome to the wonderful world of Auto Repair. Technicians get the same kind of information many times. The sad part is it isn't always correct. Off the top of my head I don't know where your particular flasher is, but I would say if the info you have is correct, it is up under the dash and may require various components. To start with you should have a flsher on hand so you know what you are looking for. (webmaster-please don't edit my answer except for this sentence)
