Rear Tail Light Sockets
Are there other GM cars that share the same rear light sockets as my 96 Cadillac Seville STS ? (Tail Lights, Brake lights etc)

The Cadillac Seville caught its breath in 1996 after going through some serious changes the previous few years. The only new aspects to the midsize sedan revolved around minor adjustments to the dashboard and interior. The 1996 Seville comes in 2 trims: the SLS and the sportier STS. Both trims use a 4.6 L V8 engine with 4 speed automatic transmission. The SLS packs 275 horses under its hood while the STS packs 300 hp.
Other features have stayed the same from previous years. Gas consumption runs from 17 mpg in the city to 26 mpg on the highway. The '96 Seville seats 5 and has 4 doors. Standard features include air conditioning, power windows, power door locks, and ABS brakes. Sunroof comes optional on both trims. Leather seats come standard on the STS.
Overall, it appears that Seville owners have a choice to make. The car performs and handles as well as it always has. However, drivers report oil leakage and mechanical problems after a few years of use. Make sure to do your homework before you buy a used Seville.

So my issue is that my car ran perfectly fine but did overheat but was still running good. But the battery kept going dead and I went to get a new battery but it wasn't the group 78 was 76. Well I put it in the car and it started right up but white smoke was coming from the tailpipes. Well I drove to a nearby Walgreens to get antifreeze and put it in and as I was driving out of the parking lot it wasn't going into drive it kept rolling backwards!!! I hit a parking lot post.. Well I drove down the street and shut it off and got out to look at the dent which was right in the middle of the trunk. Well awhile after I started it back up and it still had white smoke coming from the tailpipes. So I shut it off. Didn't start after that and I had to get it pushed back the old fashion way fender to bumper. Well I did go and get the right battery for the car and it still has not started just cranks. What do I do now.
MY 1996 CADILLAC SEVILLE OFTEN STALLS THEN WILL NOT START WHAT COULD BE THE PROBLEM
My turn signal don't work and I got told the problem is the turn signal relay but I can't find where it is located
Would a 2002 Cadillac DeVille parts fit a 96 Cadillac Seville
