My new-to-me 1994 XJ12 has seems to have zero power at the climate control panel.
None of the buttons or dials do anything at all. I seem to recall something in other posts about a microswitch inside the guts of the control panel.
I have checked power at the fuses for the LH and RH blowers and I have power on both legs of each of those fuses.
Is this lack of any reaction to pressing any buttons or rotating either of the dials on the climate control panel a good indication that this microswitch inside the control panel probably is the issue?
Or could it possibly be the Aux power relay DBC10009 ?
