Owned my 2007 Dakota 4.7 Quad Cab for the last 3 years. Not a mechanic guy. Found out window switches or motors go out easy. If lights don't come on open all doors and "reset". Check engine light was an unconnected wire. JET chip fits and works. Is on the minivan chassis. And it can tow (trying its heart out) a U-Haul trailer with a 350Z.
