I recently bought my first Jag, a 2007 XKR convertible in Indigo Blue. As I've gotten to know the car, I noticed that the driver's side power seat adjustment switch cap for the forward and backward adjustment is loose to the touch. It functions just fine and you can't notice much by looking at it, but I'd like to replace that cap such that it's nice and tight again. However, I haven't found just the switch cap, I can only find the entire seat controls switch and panel assembly, which is more than I need.
So my question is this: is it possible to just replace the loose switch cap, or would that require a whole new switch panel assembly? If it is possible, what's the part number?

 

Only the assembly, and sometimes those are difficult to find for under a couple hundred bucks. You may want to try to fix the problem yourself, if it's just the plastic button that is loose and not the switch itself. A soldering iron carefully applied to plastic can fix a whole lot of problems.
