Power trunk


Recommended Posts

 I recently replaced my hail damage trunk with a new trunk lid. After swapping all the parts, the power trunk option on the trunk let itself, the interior of the car, and the remote are not working the power trunk.  I have played with the valet switch and that has not changed anything.  Power trunk was working, before I changed out the new deck. Is there a fuse or a reset procedure I need to do to make this work again?
