I carefully removed the non-working fixtures along with shutting off the electricity at the breaker. The two fixtures are different so I matched each one with its counterpart. The fix is just a matter of getting the two plugins on each light location to mate with their female socket. The lenses snap-in and you're all done. The fix went well and I took my time, about 15 min. Do not try forcing the socket wires into the board they only go one way. You only need a flat head screwdriver to pry the fixtures out-be gentle.
