Hi, I am running out of ideas and I need some brain help. I've been working on the sunroof of my 87 300SDL. I replaced the arms because they were broken. Put all back together, it worked for a short while (open, close, tilt) and suddendly it stopped working. Not even a click when I push the Switch. I thought the motor went out but I removed the sunroof cable completely, tested the motor and it works fine (forward and backwards). Intalled the wire back, tried again and does not work. Not even a click. I am frustrated and out of ideas. Any thoughts our there? Thanks.
