Anyone familiar with taking the door's window mechanism apart and putting it back together again? My window won't move up or down properly and keeps going in the opposite way—likely because it thinks it's closed—since the mechanism is jammed—and it makes a horrible noise.
I've looked everywhere online, but I can't seem to locate any information about this model, which is from 2010.

Super Megane 3 CC Passenger window control
NOTE: In order to remove the bolts, you'll need a socket set with Torx drivers. The door card uses two different sized Torx screws.
Remove the door card (it's held on by five screws). The passenger regulator has broken on two of my Megane 3s, so I know just how to remove and replace it. 2 of them are concealed; one is behind the handle, and the other is behind the small triangle-shaped ornament on the front corner. Two more are on the underside, and one is on the left as you face it. Before you can unclick the door light and handle pulley cable, you must pop out the light. After you remove the door card, you'll notice that there are multiple bolts that must be removed. The white foam covers must also be carefully removed in order to access the area. Carefully remove the window trim; it is fragile and may break if handled roughly; I had to unhook the glass before I could pull it out. In order to remove the window, you must first loosen the two bolts that run down the underside of the pane. To remove them, you'll need to adjust the window to the right position; if that doesn't work, you'll have to take the motor unit apart. The window may desire to lower without the motor halting it, so be cautious again. After you've taken care of that small matter, you can proceed to unbolt the window regulator and carefully remove it from the bigger of the two holes at the base of the door that were previously covered with foam. Good luck with that; removing it will be a pain; you may need to close the regulator, rotate it while it's in place, and try different angles before you succeed; then, after you've removed it, you can simply reverse the process to install the replacement.

I am grateful for your quick and thorough response.
Your procedure seems a lot like one I've seen in a YouTube video, but I don't think it will work for my vehicle. Instead of a scissor system, mine appears to be cable controlled. In my opinion, the first generation of Cabriolets adopted the same strategy as the second generation, and the switch occurred at some point after the 2012 redesign.
The door's hinge side has a single white foam cover, and a metal panel attached with screws holds it to the opening portion of the door. I am considering including some images
