I just purchased a LHD 94 XJS 4.0 convertible. I have been "fixing" a few problems, but there is one I cannot solve. The small buttons above the thermostat knob and blower fan knob (ac on, recirculating, demist and manual buttons) will not come on. None of these small buttons will light up. The thermostat and blower fan works fine switching from heat to fresh air. I have reviewed the wiring diagram without luck. Any help really appreciated.

Bensjag, Welcone to the Delanair 111 club. My unit has indicator lights that do work, however they have no function as far as I can tell. All my heat comes out at the defrost vents. I still have not found the inlet for outside air into the cabin. The recirc function does not work. I sure wish there was more access to this heat/ac unit.
