So I replaced the bulb for a led bulb, that did not work then I bought two more led lights drilled to holes in the shield.
Ok got a bright heat circle but on the left ,on the fan speed only the number 4 lights up, and the ducting control only has 1/4 of the circle lit, help it is really bugging me anyone have a fully lit climate control mind telling me what he did to restore it after 20 years?
