Ok,
The car... 2000 seville sts, The problem.... All interior dimmer controlled lights on the dash are flashing constantly. The flashing is not equally timed, it's inconsistent yet constant. I have checked the connections on all of the following... Fuses/relays/dimmer switch I also disconnected the battery thinking it could be a security system malfunction, but no luck. No codes are present, which just baffles me. So has anyone else had a similar issue, and what could be the culprit of this problem?

 

just a question for you.... does the fuel gague work properly?? if so, have you considered changing the headlight switch it-self?? i think id start there. do you have the stuff to check the switch?? IMO switch. now if there are other electrical issues running wrong, then let the forum know....
