Kia Ceed (Vr7) 2012 just about to get its MOT.
Yesterday (frost on ground) neither front door would unlock - rear doors operating ok. Climbed over seat and ran engine to get internal temperature up to about 12 degrees and eventually could open drivers door. Drove 20 yards and re-parked with passenger door in weak sun and left for 1/2 hour. Passenger door then would unlock.
This morning it's zero degrees again (no rain overnight) but drivers door unlocks ok - passenger side still not working even after intenal temperature up to 20 C.
Google shows others with same /similar fault back in 2009/10 but I have not found a clear resolution.
Does anyone have any knowlwdge of the fault? It is not frozen water sticking the rubbers. The door mechanism does not clunk when the internal/external handle is pulled.
