Although the doors lock when in drive and unlock when in park, I cannot use the buttons manually. Yikes, getting old locking all doors in such a huge car. Could it be a fuse? Since my windows work, sometimes lol
U will need to check the fuse.U will need a testlight to do some checking. Check the lock fuse if good voltage. Remove the lock switch plate and check for power to the orange/black wire to the lock switch and that voltage goes to the other wires when u lock and unlock the switch.
