My wife has a 2002 Chevy Malibu. Recently, when she puts on her turn signals, they sometimes stop flashing. As bad as this sounds, when she hits the dash above the instrument cluster, they start working again. My question is, what is the name of the part that could be causing this? I have no problem disconnecting the battery and pulling the dash apart to replace it, I just have no idea what to reference as the part when I buy it. Thanks for your help.
