So recently on my wife's 08 when she locked the doors the drivers side rear door doesn't lock and more with the remote, and now it's starting to have issues with the manual shift on the auto shifter lever. when she's driving and hauling a trailer she wants to drop it to 5th so the exhaust brake works better and it won't do any thing,but it will intermittently work and some times it won't. When it's doing this the exhaust brake doesn't work as good cause the rpms are to low in drove and won't hardly work till the trucks warmed up. I've about had it wi5h the electrical gremlins this truck is having. .
