Alright so last month I purchased a 2012 Dodge Grand Caravan and it was an SXT model and it has this charcoal grey/black color on it but the problem is although it is an SXT model it doesn’t have an power sliding doors and I’m pretty sure the SXT models have power sliding door since I have another 2012 SXT minivan and it is equipped with this option. Is there any way possible to have it installed since based on the vin number it is an SXT meaning it should have the harnesses or wires built in.
