Turn signals not working
#1
Purchased my 72 Mach 1 in March.  The turn signals worked but now they don't.  I have replaced the flasher and the turn signal switch.  All fuses look good.  I do not hear any clicking in the flasher unit when the turn signals are used.  All lights are working including the hazard flashers. Any thoughts?  Appreciate any assistance.

Other then trying another flasher can, just to be sure you haven't gotten a bad one. It sounds like you've replaced the only other piece which is the turn signal switch it self. It isn't impossible the turn signal switch itself could actually be bad? Have you checked for power at the signal can? You should have 12 volts on one side when the signal is activated. If not follow the wires back as they come out of the turn signal switch, don't forget they also go through the brake light switch as well. The more I think about it. I believe you have a problem in the new signal switch, seeing as your 4 ways work, but the signals don't??? and they come out of the same switch. Hope it helps.

Did you replace the right flasher can? There is one for the indicators and one for the hazard lights. You might have swapped out the wrong one? I think the one for the indicators is above the glove box.

Thanks for the suggestions.  I was able to get them working again by cleaning up ground wires.
