Its been over 1 1/2 years since I last posted about this subject. I finally gave in an took it to my W113 expert shop in town. After $8K in repairs to other problems, he told me that he could not get the handle to work.
If I remove the door handle, It works perfectly, the button pushes in, then springs back. I cleaned it various times with Houdini as well. When I mount it in the door, and then press on the thumbpiece, it stays down and will not spring back. I have looked at everything in the door panel, but cant understand why its doing this. I had another shop look at the pictures, but still no cure.
This has become my New Years resolution to get this fixed. Any thoughts?
Merry Christmas!! (Sorry I am not PC)
