Hello, my problem started with a troubled fuel gauge not working at times more likely when tank not on fuel. Months after, one day I got a no start waited 20 min then started, no clock or radio, no power windows, no door locks, no trunk,
dash lights on air bag, security, battery, abs, ect. Got the caddy home next day no start; hooked up jumpstart. Has been starting for a couple days with all the problems listed; I'm charging the battery any suggestions ...please
Thanks!
