1995 No heat or A/C power - nothing works?
I borrowed a friends complete control panel and tried that but still nothing worked.
I have nothing operational in the HVAC control panel. The one heavy orange wire that runs to the panel does have continuous 12Volts but i cant see where as that wire even has anything to do with the power supply anyway, it dead ends into one of the connectors.
none of the switches or controls get any response.
I checked EVERY fuse in the fuse box and in the underhood relay panel.
I ran a hot wire to several of the connections at the dash and i can hear the electric doors opening and i can get each of the fan speeds??
