WE just bought a 2006 Dodge Ram 3500 Laramie, after getting it serviced on the way home we noticed a red blinking light down by your legs (near where you pop the hood)
It wont go out???
You've posted in the 2011 section of the site and your truck has little to nothing in common with a 2011 truck. You may want to find the area of the site that specializes in 2006 model year trucks and post there. Sorry I can't be any help with your problem.
