Just bought a second-hand (Sept '02) Mondeo, and the button which selects Recirculated Air/ Outside Air doesn't illuminate, so I don't know which way it is set (except by smell!).
I *could* take it back to the dealership and have a moan, but how easy/difficult is it to replace whatever illuminates the button, and how is it dismantled to get at it?
All help appreciated.
