Have a 96 Toyota Previa. Opening the sliding door every 2 to 3 days is no problem. If we do not use sliding door over a week, the door becomes very difficult to open.
The door does move a bit suggesting lock is disengaging and Panel in dashboard sometimes lights up to indicate door open. But door will only slide open after several strong tugs.
Tried greasing every movable part. ie the lock, and parts that engage with body at both ends of door. This has made no difference.
Any ideas?
Anyone else have
