Need help with 2003 Silverado turnsignals..

gunner1 · 01-30-2007, 06:14 PM

I have a 2003 Silverado 1500 Z71 5.3l that when I turn on the right turn signal, they all flash. It Doesn't happen when the left one is turned on though. Now, I've grown around GM products pretty much my whole life and if I remember correctly, this would indicate a problem with a ground, socket, or bulb on the right side. Sound right?

it is either the bulb or ground or the wire hareness for the trailer lights shorting out. it could also be a short in the wire for turn signals or in the switch in the steering colum. try the bulbs first then try the trailer harness. the grounds.

i would not think it was the bulb. i would check it still but i would lean more to a wiring prob.

If I remember correctly, I think it has onlt happened after going through a car wash.
