So my 2004 Aviator sat for about 3 months on a trickle charger since it is mainly used in the winter. I went out the other day to drive it since we got snow and i suddenly have no instrument cluster. Not just the illumination, but the gauges themselves are not functioning (e.g. the speedo and tach sit at zero even while driving). I do however have headlights (not auto, have to manually turn them on) and turn signals. Additionally the climate control has zero power. I swapped out the climate control unit with another one and have the same issue. I've checked all the fuses and they test good. I'm at my wits end trying to figure it out. Any ideas?
