friend has car that elec.window is stuck. Batt. also gets drained, got new one, still being drained wha is it

Question

My friends passenger window is stuck in the open position, its electrical. Her battery keeps getting drained even after buying a new battery. Could it be window that is draining the battery or is it something else like alternator. Car runs fine but something is draining battery!

Answer 1

Take the ground (negative) battery terminal off. Put a test light between cable and battery post. Pull fuses one at a time till light goes out. That is the circuit that is draining the battery. There are some circuits that always drain slightly eg. clock. A test light lights at about 1 amp draw. A 1 amp draw will drain a battery in about 70 hours. Higher draw = faster draw. Should be able to buy test light at auto parts store for less than $10.00.

Problem could be window, or trunk light, or dome light, or glove box light etc.

Answer 2

Every electric window in a car has its own motor inside that door. It sounds like the motor has shorted out and is draining the battery. to replace the motor you will need a drill and a friend. The drill to put the facia back on the door, and the friend to help work the motors in and out of the door.

Answer 3

If the motor or switch are drawing power it will drain the battery. Try taking the fuse out for the stuck window and see if that helps. If it does take car to a shop and have them find out if its the motor or the switch that's bad.

Answer 4

Sounds like your friend has an electrical short. Most likely caused by that stuck window.

Answer 5

it could be either the alternator or an electrical short some were as for the window it could be the motor

Answer 6

Look into the window's "actuator". I had the same problem. The battery _may_ be a different problem. Good luck on finding the solution!

Answer 7

try taking the car to get alternator checked and check fuse box
