So it appears that the compartment is pressurizing and preventing the sliding side door from completely closing, if I open the passenger door and then slide the door shut all is good however. I did notice that there are vents in the rear tail lights, however they do not seem to be doing the trick. Any suggestions ? Also, what is some good lubrication to use or maintenance that should be performed on the sliding door / tracks ? This is the first van I owned with a sliding door. Also, what is some good lubrication that should be used on all of the other door hinges ? Key locks ? Also, what can be used on the door weather stripping to try and keep it in good condition ?
