Question about 1989 Volvo 240
Just got car.filled up and fuel gauge only registers about one-third full and stays there and does not move to full or back down as gas is being consumed.
Your sending unit in the tank is bad and needs to be replaced. There is a short in it. That is the only thing that can go wrong with it. There is probley a broken wire on it so it wont read right.

You're lucky it moves at all! The most common is for there to be gunk in the window switch. If you feel adventurous, it is easily possible to disassemble the switch and clean it up. Gently pry the surrounding trim up that holds the drivers master switches. There are spring clips at the front and rear that hold it in. You will see that it contains 4 identical switches. Gently pry out the drivers switch and unplug it from the harness. When you have the switch by itself, you will see the rocker is held on and pivots on two small pins on either side. Read carefully: When you do the following, be somewhere you can find small flying parts...not in the yard! With a small screwdriver, ever so gently pry the top hinge off of the pivot pin. When you do this, a tiny spring can fly off so go slowly! You'll probably see a mass of crud down in the guts of the switch and 2 silver BB's.Clean it all out w/ a solvent such as brake cleaner spray, replace the 2 BB's and spring and clip the top of the swtch back onto the pivots.
If this is more than you want to do, you can either buy a new switch or swap w/ a back window switch that works.
