Hello my name is Dave, I am new to this forum. Ihave an 2002 impala I just instslled a new pigtail connector on right front headlamp assembly with new hazzard warning switch and verified ground wire on radiator housing frame connection is good. All lights work but i have no turn signals. All functions on the multi turn signal switch work except turn signals. I checked fuses and relay and replaced all fuses with new fuses on both sides of dashboard and under hood. I have no idea what to check from here. Any suggestions/help would be greatly appreciated.
