I have a 1984 Regal that rear lights do not work but brake lights work, hazard lights work, directionals work but no rear running lights or plate light. Changed all bulbs and several fuses and still no luck. I am hoping that someone out here in internet land will have some suggestions as to what might be causing this and/or what to do (other than light a rag and stick it in the gas tank...LOL!!!) Thank you in advance. Lisa
