No, that is definitely not normal. You have a problem. Take the vehicle to your local auto parts store and let them test the charging system.
If you have the fan removed from the car, you can just quickly use jumpers to connect the negative terminal of the fan to the negative terminal of the battery, then connect another jumper to the positive terminal of the fan,and with insulated hands(!) touch the other end to the positive terminal of the battery. If the fan runs, it's fine.
Take the positive battery terminal loose and touch it to the negative terminal post for 30 seconds. Then put the positive terminal back on.
Run a wire from the POSITIVE terminal on the battery and touch the red wire (positive) to the window motor and run another wire from the NEGATIVE terminal on the battery and touch the green wire (negative) to the window motor. The window should go down. Reverse the wires to make the window go up.
No, Remove the terminal and clean with wirebrush until both the clamp and battery post are shiny.Re-install.The heating problem should be eliminated.
Depending on colours of course black is usually negative and the other colour (generally red but depends) is positive. Get a D-cell Battery. Now get two pieces of speaker wire. hold one wire on the positive terminal of the battery and hold the other on the negative side of the battery. touch the wires to the positive and negative posts on the speaker. if the cone moves out ward the positive and negative are correct if it moves inward then the positive and negative are reversed (out of phase.) this simple test will allow you to see which terminal is which.

touch the wires to the battery terminal
It would be essentially the same as connecting a battery in the car, except with longer cables. You would have to use jumper cables to extend the car battery cables. Be sure to follow ALL safety procedures. Do NOT let anyone or anything metal touch anything else except where you make the connections. Do not touch the metal connectors themselves. I assume there is no battery in the car. I will call the battery that is not in the car the "external battery". First connect the positive ("+", usually red) jumper cable to the positive car battery cable, & then the other end of that jumper cable to the positive external battery terminal. Then do the same with the negative ("-", usually black) car battery cable & jumper cable. The last thing you connect should be the far end of the negative jumper cable to the negative terminal of the external battery. When you are ready to disconnect the external battery from these cables, do so in reverse order, starting with disconnecting the negative ("-", usually black) jumper cable from the negative external battery terminal.
There is no ground wire. The casing of the starter itself is considered the ground. Ex. If you take a battery and use jumper cables to touch the positive lead to the wire terminal on the starter, and then touch the negative terminal to the metal casing it will spin the motor.
Disconnect the POSITIVE battery cable and touch it to the negative terminal OR disconnect the POSITIVE battery cable for about 30 minutes (either way drains the capacitors in the electrical system)
FIRST TAKE OFF THE ENGINE BRACE ON THAT SIDE, IT'S THREE BOLTS. SECOND DETACH THE POSITIVE AND NEGATIVE TERMINAL'S FROM THE BATTERY, BE CAREFUL NOT TO TOUCH. THIRD GRAB THE BATTERY AND PULL UP AND OUT. YOU MAY HAVE TO TWIST AND TURN IT A BIT TO GET IT OUT
Unhook the pos terminal of the battery. touch the pos terminal lead to the ground post on the battery. The computer is now reset. Its that easy!
