hey are you trying to take out the whole touch screen or are you trying to take out the tape deck all you have to do is pop off the front covers and there are bolts holding them in.

under the alternator

Replace it.

in the center of the firewall over the blower motor.

Replace the crank sensor as they get hot they will sometimes quit working. The temp light comes on everytime the engine is turned off and the switch is on. Next time it dies spray or pour some water on the sensor then see if it will crank and if it does you know what it is.

The Buick Le Sabre has a light-duty cable which raises and lowers the window. These cables break quite often. When they break the entire regulator w/motor must be replaced. The cable, the regulator, and the motor are only sold as a single unit.

There should be a fuse for the fuel pump check this first. If fuse is good you will probably need a pump. The fuel pump is cooled by being in the fuel. When ran low or out of fuel the pump gets hot and will blow a fuse or overheat and quit.

Best get a repair manual.

Depends if your car is converted from r-12 to 134a. It likely converted because r-12 is banned in the US.
