LOL | | | | | Joined: Jun 2007 Posts: 20 Apprentice | | Apprentice Joined: Jun 2007 Posts: 20 | Here's a turn signal question: I have a 12 volt system 1960 GMC 1000. The dash light indicates when the blinker is on for a right turn, but not a left turn. New switch, set right. Lights are working (blinking), just the dash indicator light doesn't blink, and only on left. Any thoughts?

Bill | | | | | Joined: Jun 2007 Posts: 20 Apprentice | | Apprentice Joined: Jun 2007 Posts: 20 | Yes, actually redid the dash, new bulbs, cleaned the contacts,etc. Works perfect for right turn, just not left. Been this way since day one. I guess I just need to retrace all the wires for this, it must not be getting feed for the left signal. I am guessing that there is separate feeds for left and right, otherwise it'd make it a four way all the time! Just hoping someone had this trouble before. Call me lazy!

Is there a possibility that there is only one dash mounted turn indicator light on this rig. This would flash with a left OR right turn.
This wouldn't explain why yours doesn't operate with a left turn though. Could it be something in the flasher unit itself?

Looking at a wiring diagram, it sure seems like it has to be the turn signal switch...you indicate you have installed a new one though. http://www.6066gmcguy.org/turnlights1.htmStuart | | | | | Joined: Sep 2007 Posts: 26 New Guy | | New Guy Joined: Sep 2007 Posts: 26 | Kanskybrian, are you using one of the kits that include a switch and flasher? I'm trying to install one on my 48 five window (6V) and am having a heck of a time figuring out why the turn signals won't work. The stop and tail light are working fine. | | |
