Issue with locks.
 

New member and just bought my first MB yesterday. It's a 2002 SLK32 and is a great car, I hve found one problem that i hope someone can help with. the passenger door does not lock or unlock with the internal switch or the remote. The trunk will unlock but will not lock except with the key. I would think actuators but not sure with the trunk issue. Thanks and I look forward to joining in on forum discussions.
