Where to find your model number

Installation guide - Replacing a car switch
General guidance for this part type - always follow your device manual- Plastic trim tools
- Small screwdrivers
- If your switch sits behind the steering wheel, removing the wheel means removing the airbag. Leave that to a professional.
- 1Make it safe. Engine off, key out.
- 2Find how it is fitted. Window and dash switches usually pop out of their panel with a trim tool. Stalk switches sit behind the steering column covers.
- 3Remove the old switch. Lever it out gently at the edges or remove the column covers and its screws, then unplug the connector by pressing its tab.
- 4Fit the new switch. Plug the connector in until it clicks and press the switch into place, or screw it in and refit the covers.
- 5Test every function. Check each position (all windows, indicators, wipers, cruise) before final fitting.
This is general guidance for the part type, not a model-specific procedure. If the part does not fit without force, stop and recheck compatibility.
