Hello all, My 1985 Eldorado HT 4100 is running very well. But I am having electronic climate control
problems with my refer/fan/heat controls Climate controls.. When the ambient temp is up I have no control and the
fan is on high and that’s it... no indicator lights or nothing. When the ambient temp is cool like in
the morning walla everything works.... what up any? direction from anyone would be appreciated exhausted looking? Wayne

If I recall correctly, there is a control module on the HVAC box, down stream of the blower. Follow the blower wires to it. That would be my guess.
