Good evening. With my TGA with ne`m XXL house the right window lifter does not go. So, door panel off and off we go. Hmm, plug off, totally simple. Think, disc drives down and down. No matter which of the 3 buttons is operated. I pole the plug for the power supply around it goes up again. Just not off. The statement of the branch: reverber in the sky. So new drive built – and – exactly the same crap. Easy perplexity in the branch. Without the reverberator The motor runs in steps as if the reverberationers were broken. Has anyone already got to know the phenomenon and be able to eliminate it? Many greetings s`s explorermaennchen.
