So I've put led bulbs in the parking lights and taillights of my 67 coronet. Turns wont come on with the factory flasher, so I bought a no load flasher. Right turn signal works. Left turn signal works but both parking lights flash at the same time. Put in a new flasher with a ground wire in, ground wire to the heater box. And nothing. What am I going wrong? What should I look for?
 
"What should I look for?"
A good price for 1157's by the dozen.
 
Ok thanks for your help, but I'm wanting to see about getting the turn signals working with led bulbs.

Is the heater box well grounded? Sounds like a ground issue or faulty LED. Have you tried switching LEDs around?

The flasher switch ground wire should be attached to your dash frame or body ground, not the heater box. Secondly, try an alligator clip ground wire on light housings themselves and run it straight to the negative post on the battery. Report back.

Thank you. Thats exactly what I needed to know. I'll definitely let you know what works.
 
Well it didn't work. So I guess its not meant to be. Out with the garbage led bulbs and back to the stock bulbs.
