Front windshield wipers doesn't work no matter how much I use the wiper stalk. So I've done some troubleshooting.
I started with controlling the fuse for the front windshield wiper i found out that it was still operating. A 20 amps fuse. I've heard that in the Fabia mk I there were two fuses for the windshield wiper. Does anyone know if this is the case for the second generation as well?
Further troubleshooting
I started by removing the centre stalk unit, the levers behind the steering wheel that are used to flash highbeam and wipe the front and rear window. Tested with two other centre stalk units, one from 2008 and the other from 2011 with exact article number matching my car.
Same result, I can still flash indicate and use the wiper blade to the rear window. It is still possible to press the trip button on the wiper lever to change from fuel consumption, range and so on. That also worked with the 2008/2011 centre stalk.
Then I removed the wiper arms and wiper motor. Tested with two other motors from the exact same model as my car. There was no difference either. Checked the wiper linkage, and they had not been rusted or affected by verdigris.
I measured the plug to the wiper motor, and it showed current from time to time. What I can remember. No reaction in current when I pressed the lever, like crazy.
My conclusion is either that it is the relay. But according to those at Skoda, they claim that then I wouldn't been able to see any flow of current at all in the plug/connector to the wiper motor. In case of a bad relay.
Alternatively, the control unit where the relay is located that does not function. As this seems like the most logical thing, I still hesitate. Because then the car should
have several problems, and it does not. Due to the faulty control unit. But replacing this is expensive and also in need of programming, immobilizer etc.
Good to know is that the previous owner has placed several fuses incorrectly. For example, a 20 ampere, where in the instructions manual it should be a 15 ampere. Could this have something to do with the problems i am having? Everything in the car goes as it should what I have noticed. It has been debugged and no error codes.
Please excuse my english I am Swedish.
