Baffled by this? My key fob locks all the doors as it should, but the side door then doesn't unlock?
I've stripped the panels off, wd40 everything.. one time it worked again as it should, but once left a while... side door fails to unlock again?
Spring pin connectors seem fine , the pillar connection has no copper grease but surely can't be that ?
Help appreciated

If it's the same as a van of mine that did the same. Three wires into the lock solenoid...one was loose. Would lock but not unlock.
