I know this is the way our cars are but this is annoying. When giving a turn signal the relay (i suppose) clicks on and off. It has that distinct metal tab pinging noise. 1)Is the turn signal relay causing this or something else? 2) Is there an interchangable "part" from a different Gm that will be quieter like a grand prix er something? If not thats cool, dual exhuast will take care of the pinging turn signal. Thanks for any help.
