1993 pathfinder se , no lights or functions on push buttons on climate control. All heat comes out defrost. This unit has slide control heat that does regulate heat. This is same unit used on 1993 24osx models. My original manual does not show same unit as on my pathfinder. I cannot find location of fuse or relay that controls this unit after very extensive internet and forum searches. Can anyone please help? Thanks
