2003 Cadillac Seville died while driving said anti-theft

Asked by Sep 19, 2016 at 10:50 PM about the 2003 Cadillac Seville SLS FWD

Question type: Maintenance & Repair

I have a 2003 Cadillac Seville. When driving it the
other day shortly after taking off the car died an
anti-theft popped up for a second. The car locked
itself and windows did not work. But I've also
noticed other things messing up like the
environmental controls kick on. The engine cooling
fan also stays running while the key is not in the
ignition. The display also says headlamps are
suggested in the middle of the day. On another
thread I learned to check the ground wire going
from the alternator to the frame when I did it was
broke. After replacing the ground wire still no
change. Now I am stumped. Wondering if when the
ground wire broke if it could have caused a
problem with the computer or something like that

Definitely an electrical problem. Sounds like a bad relay, my car also does the cooling fan thing and likes to turn on the heat full blast when I press a/c.
