Mazda 5 Sliding Door Won T Open

If you warm up the car in a warm garage or run with heat on high for an hour or more the locking mechanism will work again.
Mazda 5 sliding door won t open. A temporary fix is to spray grease into the rear locking mechanism in door not the latch on the van body and saturate it so that the latch mechanism stays slippery. Repeat weekly in cold weather for optimal results. I managed to get the inside door handle cover off from the front. The problem child is the driver side sliding rear door.
For a while it was hit miss and sometimes it would lock and other times not. I am trying to figure out how to open my wife s passenger rear sliding door on her 2007 mazda5. The outside handle literally came off in my hand. Opening door on mazda5 when child lock is engaged and outside handle is broken.
