Evora window regulator cable repair
The window regulator seems to be a common failure point in the Lotus Evora. Unfortunately, you cannot replace components of this, as the regulator must be purchased as an entire assembly at a cost of several hundred dollars. If you have the dealership or a local shop do the work, the labor charge will be at least as much. Fortunately, some common window regulator problems can be handled by yourself with a few dollars, a few more hours, and a modest mechanical aptitude.
My problem started when I rolled down the window one day and found it wouldn’t roll back up. I could hear the motor whirring, and a slight crunching sound, but no movement. Lack of movement in one direction when the motor still whirs upon clicking the button is a good sign that a cable has broken and the motor is fine. Here is how I repaired mine.
First, you must remove the door panel. There is already an excellent DIY here on this forum which I followed. I do not have much to add except to say you should really use the special tool (as recommended in the tutorial) to remove the plastic “fir tree” snaps. I first thought I could just use a flathead screwdriver. Nope. Save yourself some trouble and buy this tool at your local auto shop. It is often included with other similar tools in an “interior/upholstery removal tool kit”.
Now that the door panel is off, it looks like this. BTW, my Evora is a 2011 so yours may differ somewhat. Familiarize yourself with the various components, bolt locations, etc. The interior panel is connected by the door latch cable and the wiring harness. The wiring harness has plastic zip-tied over the two connectors, so have some spare zip-ties handy when you eventually put everything back together. The inner chamber of the door itself is covered with a foam (plastic on newer models) liner glued to the door. Remove this. You may be able to remove carefully enough that you can re-glue it later but expect to have to replace this with a new piece. I bought some similar material at a hobby shop and cut it to shape. The purpose of this liner is to prevent water from dripping down the glass and finding a way into the vehicle cabin.
