Both Electric Doors Suddenly Won't Close?

[Nick13]

Just upgraded from 2002 voyager to 2009 today! And both the side doors have suddenly started playing up, both try to close but stop after a few inches and revert back to open, this happens with all the buttons and fob. Strange thing is they both worked fine this morning.

I gat a 2008 18 months ago and side doors used to play up, sometimes close fully others part close then reopen.
I got some Maintenance spray (WD40) and cleaned the tracks, rollers and anything that moved when the doors moved and operated them manually a few times to ensure everything free and easy.

No further problems, it may be down to lack of use hence something like a roller may be tight.
I also use some engine oil on the moving parts now and again as this works better than WD 40 for actual lubrication.

Do NOT use grease as this only covers the outside parts and no penetration to axles and pivots.
