power door lock failure

door locks failed, found cig light fuse broken, replaced, blew right away, cant open rear hatch, is there anyway to open the rear door manually?, any idea why fuse is blowing?, thanks

That can frequently be from a shorted/failed door lock switch. Moisture from an open window in the rain can wreak havoc on them. Pull teh door switches and try another fuse or measure the circuit resistance.

You might also want to pull the lighters and accessories from all the power sockets on the van and check for foreign objects.
