This is a 54 reg Touran Sport. The middle button on the remote opens the tailgate, but not anymore. No matter how long you keep pressing it the tailgate won't open, click pop or otherwise respond.

Also the rear wiper doesn't always work. I think it has to do with opening and closing the tailgate, some sort of contact being made, or rather not being made.

Finally the spray on the tailgate won't spray, or won't spray a lot, just drops.

Sorry for the long post.

Thanks in advance.
