First tried just to replace the top door switch and it was still not consistently working. So order the whole holder assembly. When installing the new part, noticed there was a clip towards the bottom that I didn't see before. I believe the first fix probably would have worked had I snapped that in. But the new piece came with new switches so felt better about installing the new holder to at least have all the switches updated. The two screws that tighten down the holder could use a stubby screwdriver or some ratchet set up. Estimated time was for both repairs. When trying to replace just the door switch, the wires didn't separate very well and ended up breaking the switch I was replacing anyway,
