Thank you for your information. I contacted the shop an requested a confirmation that the problem is the actuator; the shop confirmed the exposed wires short-circuited damaging the actuator; they offered to keep the old part to show me. The shop also mentioned that they repaired three other MB with the same problem, one of them had also the control unit (computer) damaged from the same problem. I hope I'm not getting ripped off. I really like my 94/E420 and have not had major problems, having plans to keep it and use it for some years to come.
