Hello and welcome to Just Answer, my name is Matt.
Van has power sliding doors and power liftgate, correct?
Do they work at all?
Will they close with power?
Did they all stop working at the same time? Or one by one?
side doors have not been working for months,rear power liftgate stop working today
One more question....do the doors work manually?
The sliding doors have 2 common problems. The ground wire to the door breaks inside the plastic chain. The latch fails electrically.
On the liftgate, the common problem is the latch.
Have you checked all the fuses yet?
Let me see if I can get you the fuse numbers to check
Is there any other electrical problems with the van that might be related?
side doors do not unlock/lock automatically
remote entry does not lock/unlock side doors
fuse 31 and 32 (both 40 amp) in the fusebox by the battery
those fuses send power to the control modules for the doors and liftgate
will check these fuses
OK, check those...really, check them all. If the fuses are OK, try disconnecting the battery for 10 minutes to reset everything. Beyond that, you will need to get the dealer scan tool connected to diagnose this. The doors and liftgate are electronically controlled, so the scan tool is needed to diagnose the systems.
