One of the last (yippee!) remaining 'issues' with my car was a rather slow rear, driver's side electric window. The rear windows tend to suffer through lack of use and I noticed that it always needed assistance to shut. I mentioned it to my local dealer and he passed on a simple tip which worked perfectly. Simply lower the window and spray some silicon-based product onto the seal on each side (where the window slides up and down). Run the window up and down and check the smooth running, trouble-free operation . It seems the problem is very often simply a dry window seal, which means the window sticks...
