I noticed my turn signals seemed to blink a little faster than normal, but didn't worry much about it. But I drove my car the other night (unusual) and when I pulled the headlights on, the turn indicators lit up some along with the bright light indicator. Am I looking for a under dash ground problem or one near the actual lamps?

 

i think they ground near the headlight on the rad support not postive though and the back s ground inside where you unscrew the light assemblies

 

check your parking lamp bulbs...

 

Ok, so I still have this going on intermittently and I tried fixing it today. After I finally found G200 on the "convenience center", I loosened and retightened it. That didn't seem to to fix it. I also loosened and retightened the headlight grounds. No help.

I can bang my hand on the bottom of the dash with the knee bolster removed and cause it work properly. It's obviously a ground, but not the G200 instrument panel ground itself. It's like the bracket and dash metal isn't grounded good.

 

After tinkering yesterday and burying my head in the factory manual, I believe it's going to be in the C2 connector to the instrument panel. Pin 14 is the ground that should be used by the bright light indicator and the turn signal indicators when they are being powered by the flasher. I believe this connection, factory splice 205 or something in the instrument panel circuit board itself (such as a crack) is causing this ground to become intermittent or to have small amount of resistance.

If that ground path is severed or has high resistance, electricity will find its way to ground thru the front turn signal indicator bulbs and then thru the actual front turn signal bulbs themselves since they are very low resistance when not lighted.
