I CHECKED THEFUEL CAP  AND IT IS FINE AND TESTED FINE YESTURDAY.MY QUESTION IS: CAN I RESET THE COMPUTER OR CLEAR THIS OUT MYSELF?

Answer
HI Stan, Unless you have a scan tool you will have to go to somewhere that does and they can clear the codes from the PCM to turn off the light. Starting with 1998 on the Seville Cadillac changed the way computor information was accessed while the Deville and Eldo you could still press off and warmer for a couple more years yet. That is why I suggested AutoZone because they will scan and clear codes for free in hopes you will buy their parts. Bill
