I have a 2009 silverado. It only came with the basics. Iv added the power door locks at the dealer when I purchased it. Although they for got to connect the actuator to ONSTAR. Im looking to install power windows on the truck. Im not sure what kit to buy. Or maybe i should just take it back to the dealer. Im trying to avoid that considering they didnt do a good job with my power locks. Any help would be very appreciated.
