Did you know that whether you have power windows or manual windows, the actual raising and lowering of your window glass is accomplished by the same component? No matter what type of window system your vehicle uses, you will still find a GMC C2500 window regulator located beneath your interior door panel. The C2500 window regulator is a series of gears and arms that is responsible for the mechanical movement of your windows. If you have power windows, your window regulator is powered by a small electric motor, and for manual windows, the rotary motion of the hand crank turns the gears of the window regulator.

Another responsibility of the GMC C2500 window regulator is to lock your windows in place where you put them, which is a matter of safety as well as convenience because it prevents your windows from being forced open from the outside. For this reason, a faulty window regulator may cause your windows to drop unexpectedly into the door frame. If you are having problems with your windows, and you are not sure whether it is the result of your window motor or your C2500 window regulator, there is usually a simple way to tell--just listen when you press your window switch.

If you do not hear anything, chances are the problem is electrical and due to your motor, fuses, or wiring. However, if you hear a humming or a grinding sound, then your GMC C2500 window regulator is likely stuck, and you will need to either repair or replace it.Find a great selection of C2500 window regulators right here in our online catalogue at great low prices.
