Cadillac Jim Posted July 10, 2008 Report Share Posted July 10, 2008 Bad harness connections. Codes, fuses, circuit breakers, and relays. Confused multifunction switch (inside the steering column, the thing the turn signal stalk is on). But, first, run the OBD codes and check the fuses in the maxifuse block just behind the air cleaner. Here's how to get the OBD codes: http://www.caddyinfo.com/readingcodes.html If you have a meter to check fuse continuity, that's better than just looking at them; sometimes they crack and go open but look just fine. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.
