I just purchased this truck and the dealer said do not use the lumbar control in the seat. They said that it was replaced and when they went to use it that it shorted the other controls out. So they took it to another place to be fixed and they did not fix it either so after putting almost a grand in the seat to be repaired they gave up. I love the truck just wished the seat worked correctly. Even the driver information screen won’t let you program it all the setting for the seat are off. Any ideas without taking it to the dealer I have almost no confidence in them past encounters.
