SSV No rear locks, help

[FrankU]

2006 SSV , The rear doors and the rear hatch will not unblock. They used to lock and unlock. Now they will only lock. What the heck am I missing here ?
Thanks .

You hit the nail on the head ! Corrosion on the relay connectors was the culprit. Thank you !

Have a Merry Christmas.
