The electronic dash control will only go down to 75 and if I bump it up to say 80 it won't come back down unless I pull the fuse and it will reset itself at 75 , I think I need a new or replacment dash control and have been told it must come out of or be for a convertable , coups are different ! could the problem be something else ?
