I used a flat-head screwdriver to pop out the old light rocker switch. Then, I unplugged the wires, plugged them into the new light rocker switch, and then popped the new switch into the hole. That's it! Lights began working again.
An easy job for smaller hands. Removed the two bolts holding the light cover. Removed two electrical connections from the old switch by pinching the retaining clip,removed the switch, snapped in the new one and re-attached the connectors. Your online illustrations helped me to know that the plastic housing for the light switch would only swing down so far and was not intended to be removed. Saved me from breaking that plastic cover's tabs. This home repair saved me more than 5 times the cost of hiring a professional to do it. Very happy homeowner.
I opted not to remove the entire door which did not cause any problems, and did not add to the complexity of the job by adding another step. I simply removed the numerous bolts from the sides an bottom of the existing gasket and loosened, but left in place, the top row of bolts. I slipped the old gasket out and slipped the new gasket in. Then tightened one bolt per side to secure it in place and verify it was even around the perimeter, then tightened all remaining bolts and then wait for the applause.
