In the wiring diagram for my 94 XJS, there is a 3A inline fuse on the LG (Light Green) wire (ignition switched) which goes to the Control Panel Module, and ALSO to the Climate Control Unit. Could anyone tell me where the fuse is located?

I am trying to find out why the small buttons (ac on, demist, recirculating, & manual) above the thermostat knob/fan knob do not work on my car. As posted earlier, any suggestions (in addition to the fuse location) is most appreciated!
