Question about Cars & Trucks
New turn signal switch were recently installed seeming to cause this new problem on a 1997 Cadillac sts Seville
I hate to be the bearer of bad news, but many GM vehichles have an overly sensitive "driving computer" an overly-sensitive ECM system that everything is integrated into. It sounds like whoever replaced your turn signal switch, messed up the ECM when they disconnected the battery, or they did not properly ground or discharge the system before doing the work.
On some cars, the ECM can be reset by simply disconnecting the car's battery, turning the key to the "on" position, then then discharge everything by quickly touching the possitive and negative battery cables together (NOT ON THE BATTERY, but just the cables themselves while disconnected). This doesn't always work on all vehichles, but could be worth a try since it is so simple and does work on about 25% of the cars I've used the method on. It did work on some 1998 STS's that I've done the discharge trick with, so it could be possible with your vehichle as well.
If, however, the ECM was shorted during the work, or took a hit from a really bad static discharge, then the ECM itself could require replacement, unless an authorized dealer service has a way to reset it.
