1991 Chevy ck1500
Ok I will try to give as much details as I can on this.
First off. When I turn the the lights on the left turn
signal light comes on solid and won't blink. When I
have the lights off and use the left blinker the front
two blinkers come on driver and passenger, the
driver side marker light wont come on no matter
what even with a new bulb, I replaced every bulb in
my truck. And when you use the left blinker on the
rear 2 bulbs will blink on the driver's side. If I use
right blinker that side works how it should with no
extra stuff. Any ideas?
Sounds like a ground or socket problem, these rig we're know for having trouble with the circuit board in the tail lights, make sure you have good grounds to all your lights as this also seems to be a weak spot , front and rear lights.
