Does yours have footwell lighting? If not it may simply need bulbs. My 04 TDCI Zetec had the bulb holders and the wiring in place. All I had to do was plug in 5w capless bulbs and hey presto. It makes the car a bit more inviting on these dark nights/mornings.
The easy one to describe is the passenger side, as a panel clips off and makes it easy-access.
At the bottom of the dash there's a panel, a couple of inches high, held on by 2 push clips. Pull it off towards the rear of the car, one side at a time. This lets you in to see that the bulb holder is clipped through a hole just a few inches in from the left hand side, pointing down and forward.
If you've got the holders it's easy enough to fit the bulb without taking the panel off. The drivers side is a mirror image but doesn't have an easy access panel.Edited by: dieselal
