My work has given me an 06 2500 with 89k miles that sat for about 6 months before I got it. Lately I have been having issues when using the turnsignals (more with right then left) Both dash indicators will blink. and I have erratic flash sequence. It is worse while I am braking. Work had me take it to a autoshop who said they couldn't find an issue with the truck. All bulbs have been changed out and are working. is there anywhere I can look, or tell the next shop to look for that might help solve this problem?

Thank you

 

Sounds like either a bad ground in the rear or a bad light bar in one of the light assemblies.

Oh and welcome to the forum.

 

Thanks for the welcome and the info lx. next time it's in for an oil change i'll have the shop look at those.
