Usual Problems of Your Saab 900 Window Switch and the Reasons behind Them
Not all vehicles have power windows. In fact, this particular feature used to be available only to luxury cars. But thanks to modern technology, almost all vehicle makes and models are now equipped with this very useful feature. Consider yourself lucky if you own a Saab 900 equipped with reliable power windows. However, even if the power window assembly, as a whole, is robust, its individual components, particularly the window switch, are prone to developing several problems after some time. Here are the most common problems associated with your Saab 900 window switch and their causes:
Windows that move too slow
If your Saab 900's power windows are working, but they are moving up and down more slowly than normal, it is possible that the window switch is not receiving enough electricity from the window motor and the main power source. This power flow interruption can be caused by a dirty window switch, busted electrical wirings, a defective window motor, or an inefficient car battery. If your vehicle is having this problem, you need to check the cables and other window assembly components that send power to the switch; replace them immediately if they are damaged. You may also want to check and lubricate the tracks of the window assembly components. Sometimes, the only problem is that these window system parts get stuck due to rust accumulation and/or old age.
Windows that won't work
Usually, a faulty switch can cause one or two of your car's power windows to not work. If this is the case, you just need to replace the busted Saab 900 window switch to solve the problem. However, if all of the windows are not working, you may want to check the other window assembly components for any problem that may cause this malfunction. The possible culprits are a blown-up or burnt fuse, a broken relay, or a bad jumper. You can test the efficiency of all these window system parts using a test light or an ohmmeter. If any of these parts shows signs of trouble, replace it as soon as possible.
Your Saab 900 window switch is primarily made of sturdy plastic. However, certain factors and circumstances, like careless handling, moisture, road accidents, dirt accumulation, and old age, tend to cause physical damage on the surface and body of the window switch. When a window switch breaks or if it collects a significant amount of dirt and dust, its normal operation may be compromised. A broken switch is difficult to operate. While water contamination can cause the electrical circuits to malfunction, dirt and grime can block the contact points of the switch and the wires that transport power from the source. All these problems can be prevented through proper handling and regular cleaning. However, if your Saab 900 already has any of these problems, you have no other option but to replace the damaged window switch and/or other window assembly parts with new ones.
