How do you change the dome lights? Lights do not turn on when door opens.

remove the cover over the bulbs with a small screwdriver,should have slots in it.it should be a 3 position switch ON-OFF-DOOR.maybe door jamb switch is sticking.if that is the case,spray wd-40 in the latch/switch.if not just change the bulbs or check the bulb holder,maybe spread apart a little and not making good connection all the time..if you need a whole assembly,there is a used one on e-bay for $29.99,free shipping,missing bulb cover. eBay item number:311394080306 from Houston,TX
