You will admit, it is very annoying and frustrating when some of the switches in the car do not work, especially those related to unlocking-locking doors and switches for lowering and raising windows. The latter, window lowering and raising switches are more common as a problem on the Saab 9-3 model and especially on the convertible model.
And most often, the problem is not big and does not require the replacement of a spare part, but only cleaning and lubrication, and you can do everything yourself in the garage or parking lot. This will avoid going to the service and save on your own budget.
The mechanism that moves the window up and down is called the window lifter. In some cars, the window motor comes with a window regulator as a whole, in others the window motor can be replaced separately. There is one window lifter in each door. The window lifter does not require any maintenance or servicing. If it breaks, the broken part or the whole unit must be replaced.
However, as we mentioned, the fault is usually harmless and requires only the removal of the door panel, then the removal of the switch unit and then only the cleaning of the electronic board and electrical contacts. If the signal traces on the circuit board was not broken, so cleaning it and the silicone cover with some isopropyl alcohol was enough to get it working again. Just check circuit, clean connectors and circuit board with electrical cleaner.
To make it much easier for you to determine this operation, below you can watch two videos made by Saab enthusiasts to help the Saab community around the world:
Other common window lifter problems
A bad window cable can cause the window to jam or fall inside the door.
Worn cable guides or worn window lifter cables can cause abnormal noise as the window moves. For the same reason, the window may not go down or down completely. In cold temperatures, the window can freeze in the closed position. When the window switch is activated, the window can be detached from the window lifter.
A car is considered unsafe when the power windows do not work properly. Several car manufacturers have issued a recall to address issues with the window mechanism. Fortunately, that was not the case with Saab cars.
If this guide does not help you, then it is best to contact the nearest Saab specialist service. Since proper window regulators are important for your safety, we recommend that you visit a reputable mechanic if you have problems. Electricians also have a scan tool that can test window switches, motors and other electrical components.
