Mk2 Ford Fiesta dashboard switch Panel

Across all models, on both high and low-spec Fiesta dashboards, the Mk2 Ford Fiesta has four slots for switches located to the right of the instrument cluster, three main switches and a blanking panel. It’s very common for the blanking plate to be fitted with an LED bulb for an aftermarket alarm. An optional front fog light switch is rumoured to have been fitted in the fourth slot as an option for some European countries.

It’s very simple to change the symbol on the switches, with the switch removed, they can be slid out and replaced by a different one with ease on earlier switches, or pushed out from behind with the switch dismantled on later versions. It’s a common mod to swap a spare rear fog light switches decal around to create a front fog light switch.

Switch Removal and refitting

The fiesta switches can be removed by gently prizing with a flat screwdriver or trim tool from the sides, they are held in place by two metal sprung plates which allow them to locate by snapping into place behind the panel fascia.

All the wiring connectors have a small tab on them with a ‘T’ shaped hole. These T’s are angled in different directions making it impossible to plug the incorrect switch into the wrong wiring loom plug.

Interesting Fact

The Ford RS200, a famous Group B rally car (and thought of by many as the ultimate Ford), also used 6 of the same switches as the Mk2 Fiesta, although mounted vertically.

Mk2 Fiesta Switch holder

To remove the switch holder, the instrument cluster fascia surround needs to be removed first. One of its locating screws goes straight into a metal clip in the switch holder itself. The Fiesta switch holder has two screw holes at the rear to attach it to the dash, to access these, the switches have to be carefully prized out, taking care not to damage the switch holder itself. Once the switches are out of the way, a reasonably long handled Philips screwdriver can be used to remove them.

The switch holders are renowned for getting brittle and breaking easily when removing the switches. They are becoming quite sort after online with people asking upwards of £50 for an unbroken one. They can be carefully repaired in several different way including epoxy/plastic welding or reinforcing from behind using thin metal plates. It’s worth noting that both the high and low spec dashboards have different switch holder panels, and it’s much easier to get hold of a low-spec version as the basic dashboard is much less popular.
