Repairing the Air Conditioning Display

Model: Saab 9 5 Ys3e, MK 1 - Years 1997-2010
Part: Air conditioning

To perform this repair operation, it may be useful to use a type of capacitor as a filter. Of course, you must work to maintain the correct polarity between the electrodes, otherwise, you risk damaging everything. To repair the computer that controls the air conditioning, the first step is to remove it from the slot where it is housed and disconnect the wiring harnesses that connect it to the car. Then, remove the 4 screws on the back with a flathead screwdriver. Once the screws are removed, you can extract the board and circuit to work on it. Once the pins have been soldered, you should be able to pull out the capacitor from the front using stiff wire, allowing you to insert the new capacitor. This way, everything will be back to functioning correctly. To reassemble, simply perform the operation in reverse order to disassembly.
