hello,
Steps to remove the switch are as follows:-
Actually U need to extract the CENTRE PANEL inclusive of radio, fan control knob, climate control switch units,9 screws plus the 2 trims. These require diagram to dismantle them. (tedious works & require special tools to extract the radio). Try to do the short cut ways! just to check for loosen wiring!.
1. Inside the cigar ligter, there two screws (left & right} undo the bolts.
2. Underneath the cigar lighter assembly, there are 2 screws.undo the bolt & extract the astray housing.
3. Under the astray housing, there are another screws attached to the dashboard, remove them.
4 Try to access to the recirculation function switch from the rear side. Hopefully it just loosen connection! The recirculation function switch is attached to the centre panel with 2 screws. During this stage changing the bulb is impossible.
Happy Motoring
