You pull over a drive-through to get your burger with extra cheese. You press "DOWN" on your window controls as you drool over the treat that will soon be yours. However, fate decides to pull one on you and your window does nothing. This causes you to stare emptily, thinking that in that very second a broken window motor is the one preventing you from reaching that awesome burger. Here is a discussion to help you know and solve the common problems with your Pontiac Firebird window motor as well as instantly reach that luxurious treat.
For your Pontiac Firebird window motor to work, it needs voltage-yup, no brainer there. However, car owners often find their window motors without voltage.
A lot of things can prevent the voltage from reaching the motor and each of them could easily be diagnosed and solved. The first things to check are the electrical connections of the window motor. You would need to test the wires for voltage using a test light. If the wirings are good, then the next thing you need to look at is the connection between the motor and the window switch. There may be cuts or torn parts in the wire, causing the problem. If there seems to be no problem, the only thing left to suspect is the motor itself. This would mean that your problem is not that the voltage does not reach the motor but that the voltage reaches a damaged/broken motor.
As one of the many ways that your car messes with you, there comes a time when the window would only go down. Despite how many times you press the "UP" button and how dusty the road is, the window just decides to sit the drive through.
Car owners blame this problem on the window motor which, actually, is not always the case. If it is a window motor problem, it probably is a problem with the voltage and you should read the first part of this guide. However, there are cases where the motor is working fine. If this is the case, there are two things that you may need to do. First, you may need to lube the window. Especially true for older cars, the window assembly may have already become too tight due to aging. Second, you may need to replace the regulator. Problems with the window regulator may cause the window not to go up or down, or both.
