Yesterday my climate control lights began working after never working since i bought my 83 300D a year ago. The little buggers even brighten up when they are depressed, i was thrilled. However the temp control and hi/low sides dont work, or do these light up. Since my middle part lights up, is it just that the fiber optic cables arent hooked up to the sides? How easy can this be done? I will look in the Haynes manual, but not sure still.
