Yes they do. You need to change the bulb that is located behind the fan control. Turn it to the second speed and pull the knob straight out.Cover the knob with a piece of rubber to protect it. (I used a jar opener gripper) You need a piece of plastic tubing to pull the bulb straight out. I got 1/4 inch diameter vinyl tubing from menards($1). Push the tubing over the bulb then pull out. Bring it to the dealer and they'll know exactly which one to give you. They gave me one free
The new bulb just gets pushed in with the tubing. Then put the control knob back in and you're good to go
Good luck. If I can do it anybody can.
