I noticed the other night when I was playing musical cars that when my right turn signal is on both front turn signals blink. But not the rear. When I put the left turn signal on everything function normally. Has any one see this before. I searched the forum a bit and did not find anything similiar.
Thanks.
Everyday brings something new.

Check the front signals for good grounds. Make sure you have 1157 bulbs installed. if OK it's in the TS switch

Yup, if you installed LED front blinker lights it can cause this to happen. I bought LED rear and front lights. The rear ones worked great but the front ones ground out for some reason. They both went on when I used left or right blinker. I almost took apart my blinker switch on the steering colum thinking that when I put it in that I put it in wrong. I was actually thinking about this on my drive home today. On how I could re-wire my front blinker lights so that I could use the bright LED lights.

If you get both lights on, it means the common leg is floating above ground potential and/or mechanically (physically) the bulb buttons are not contacting the socket buttons correctly. LEDS still work the same way as incandescent filaments in respect that they both need a source of power and a ground. electrically, the main diffence is the amount of amperage draw and the LED is solid state. Most of the time the LED circuit doesn't have enough amperage draw to heat the bimetallic strip in the flasher so they just stay on solid. Hope this helps.
