Remove the front seat can give you access to remove the panel. But if it has screws around the outer perimeter, most likely will have to tear it out. Best to find a replacement first. Look at the drivers door, if it has screws, so does the passenger side. There are screws around the arm rest and door handle to remove, then it pops off. Again the seat has to be out of the way.

It could be the window sweep set is allowing water in or the door seal around the inside of the door jam and another over look problem is that the heating core is leaking coolant in to the vehicles cabin but the leak would be close to the dash if this is the case

Hook up a sprinkler heat to a stand (to simulate rain) and turn it on then go inside the car and watch for leaks.

There is no fuel cut off switch. The electric fuel pump only operates for a few seconds when the ignition is switched on and will only remain on when the engine has been started. If the engine is not started and the ignition is left on the computer will cut power to the pump.

If you want to cut all power to the fuel pump you have to remove the fuse for the pump or remove the relay that covers the power circuit to the fuel pump.

If it's an automatic, your transmission needs rebuilt.
If it's a manual, Clutch and Pressure Plate replacement.

You may have a faulty injector that fails to shut off and is constantly supplying fuel. During operation it may not be noticeable, but when you shut the car off, the injector will pour fuel into the empty cylinder until fuel pressure falls off. This fuel will leak down along the piston rings into the oil, contaminating it. This will eventually cause cylinder wall damage due to "washing", the fuel is removing the protective oil film on the cylinder wall. This will cause much more wear on each start-up. Have the injectors tested.

Dump the oil and refill. Take it to a JiffyLube or other oil change depot. Could be that it will not continue. I would take
it to Nissan service if it were my car.

Check your fuses to make sure they are OK. Your turn signal is on a different circuit than the tail lights. I think.

No you dont have to bleed the lines . You only bleed them when you crack any lines and fluid comes out. You do need to push the caliper plunger back in to fit the new pads in so they will fit back over the rotor

Have you checked your transmission fluid If its automatic there will be a dipstick under the hood. If it is standard you need to take the plug off the side of the transmission and top it up till fluid comes back out. Were there any puddles under your car lately Any sweet smells

TCS is Traction Control System,and all TCS's are controlled though the Anti Lock Braking (ABS) system.Here's how it works:Each wheel,or in some cases,only the drive wheels have a speed sensor mounted near the hub or axle,and sends a speed signal to the PCM (Powertrain Control Module).The PCM monitors wheel speed continuously,and if it sees a speed out of the ordinary,say for example the right rear tire is spinning and traveling at a much higher speed than the left rear,the PCM will pulse the brakes through the ABS system on the right rear to slow down the right rear so that the left and right wheel speeds match up,this is how the traction control works.So,if you have a TCS problem,the PCM will see this and set a Dignostic Trouble Code (DTC).You need to pull the DTC's out of the system with a scan tool,diagnose and repair the DTC's.It could likely be something as simple as a malfunctioning wheel speed sensor,but you won't know until the codes are pulled out,as this will point in the general direction.Good luck.
