I have a 2005 CLK55 Cab. My seat stopped moving forward and back, but all other directions work. I checked all relevant fuses related to the seat and all fuses were good. After researching online for several hours people say it the forward and back motor is probably broken, however in the links I did find people said removing the seat becomes super difficult if it won't slide forward and back as the 4 bolts are hard to reach. They did also say there is a way to do it in the "archive" but I wasn't able to find the "archive". Anyone had this problem before?

Also I assume this is the part I need?
