Car runs great mechanically but the back half of my inside lights don't work including the dome lights and sunroof Car also shifts smoothly into reverse but no lights except for the brake and running lights

I have a 97 cadillac seville sts that will not start.. let me first say what I did .. 2 years ago I had to replace the alt and battery.. which I did about 4 months later (I had company vehicle so I didn't need it). then the car wouldn't start.. I took off what was what I thought was another fuel filter but turns out it was a fuel pressure regulator but no gas was coming out so I took off the connector to the fuel filter but it also shows no signs of gas being pumped. So then I replaced a fuel pump relay and a/c relay and when turning on the car the relays do click over.. so I then proceeded to take out tank to test the fuel pump and replace the fuel filter. I took pump out of the tank and submerged it in a bucket and pump worked.. but I noticed a fray wire on the harness but was close to the connector.. so first question is am I doing anything wrong? And second , which wires should I be testing to test power to pump? Pictures do help thanks

I have some air flow out the small vent that exits the back of the console but it never gets warm. It doesn't appear that the front fan is running at all. Any ideas to help me would be appreciated.

Thanks

Car won't always start with key but will with remote start button (aftermarket I believe). Engine will die when brake pedal touched unless I set the alarm (also aftermarket) open the door to activate alarm and push reset button on remote. Door lock sometimes open while driving and the alarm will go off while driving. I would deactivate the aftermarket alarm but I don't know how it is attached to the car's system.

I was charged $733 total. $105 diagnostic, $169.99 for the mount and the rest in Labor. They did not itemize the labor hours and cost. Was that total high or average? They also lost a front wheel lug nut cover and scuffed the front bumper and will not pay.

When the car sits for a little there is a puddle of antifreeze under the car.

My 2003 Seville STS, VIN 9, needs new transmission. Can I replace it with one from 2003 SLS or DeVille? Will one from cars model year 200-2002 work? If not, can I swap transmission AND computer wit SLS model? I don't care about loosing some performance, I just need to repair it for less.

I changed the trans fluid pressure switch but still have the same problem.

The car is actually a 1991 Cadillac Allante, where is the Controller for the ABS system located and how hard is it to replace?

New plugs, wires & added Lucas gas treatment/injector cleaner/octane booster. Checked Air filter/OK.

keeps cranking. has brand new fuel pump and brand new battery.think maybe the relay fuse to fuel pump could be bad? Do i need new cables to battery? I cleaned off all corrosion. Or is there a step by step process i should do it in?

The rest of the trunk is wet also. We ran water over tail lights etc. No water leaks. The gaskets look good. Can water leak in through the vents on the side/inside the trunk?? Any suggestions???
