Where is the signal light combi switch and the flasher on a 2000 grand am SE and how do you fix it?

situated directly behind the 4 way flasher button, this unit operates both the turn signals and the 4 way flashers, unit cannot be repaired , replace $40. but be careful , many times the problem is actually in the signal stock, can sometimes cause a rapid clicking noise from flasher unit even when not in use, if this is the case just turn up the radio, repairs to signal stock can be very expensive $300 to $400, I have had this problem for 4 years on my Alero , cost to repair was estimated at $400 plus labour. Did not fix, no ill effects.
