Dash lights flash with Turn Signals

[91Bluestreak]

99 Suburban

Ok with my lights off turn signal on my dash light flash with the turns. Doesnt matter whitch side either. If I turn lights on then no flash. I havent messed with any wiring on the truck. I'm thinking either a ground or the headlight switch. Any help would be great.

Something like that I would suspect a bad ground if nothing else has been messed with...

I checked the grounds under the dash and they seem fine, also swapped the headlight switch with the one from the tahoe same thing. I'm begining to think the led cab light may be causing it.

Disconnected the cabs lights no change. Look under dash for any loose wires and nothing. It has remenants of a remote car starter left under the dash, but all grounds are tight no wires were messed up during installing my gauge pod (still not wired). I'm gonna pull the grounds off under the dash and clean them and see what happens.

I'll look at them later today if I get time.

I'm betting a taillight ground. No, really. Check the bulb sockets and trailer harness for corrosion. I've had it happen.

^^^ Agreed on the trailer harness. Those do all kinds of creative things to the lights when they short out.

Correct its in the front light circuit. I disconnected the from harness and no dash flash. I'm guessing its from my father in law wiring the mirror lights to the front side markers. Thanks for the help.
