Door won't lock or open.Trunk doesn't open
BAS and ESP lights came on and did the reset by pressing the R button for 3 seconds and confirming by pressing the button again to factory setting. Now I've a new problem can't lock doors. Button at the dash to close/open doors are also not working. The latch at the trunk is also sticking out. Any suggestion what may be the problem?

My first suggestion is to reset the PSE (Pneumatic Service Equipment) computer.
Find the interior floor light behind the right rear passenger's heels.
Pull the housing from the carpeted wall.
Find the yellow 20-Amp fuse on the end nearest to the center of the car.
Remove the fuse. Make sure it is not blown.
Reinsert the fuse.
See if the door locks and trunk lock work.
