I'm not sure it's the acuator, on my 08 TL. I recently had the driver window regulator replaced and since it's been replaced. I can lock my car with the remote but i can't unlock it (with the remote) but once driver side door is unlock with key i can unlock on the other doors with the remote. Would that be an acuator issue? i can lock/unlock the car from inside no problem just can't unlock the driver side with the remote. it's very annoying.
I did have the all the wires looked at and everything apparently is connected properly after the regulator was replaced.

 

This isn't the correct forum for '08 TL's. Allow me to direct you here:
