Same situation here, drivers door actuator very loud buzz lasts about 2 seconds....sure it is actuator and was going to try and take it out to clean it but CANNOT
get the key lock tumbler from outside to disengage with the interior component....sure this has to happen to pull the actuator.....Irony, just a couple days after I pulled the panel the electric window regulator went out....thought about the repair kit because it's fairly cheap and I didn't need the motor, but bought the whole regulator and installed it, was very easy. But while I have the panel pulled I want to address the actuator buzz. Appreciate the feedback.
