I have a fiesta bj. 1992 44kw with electric window lifters in front. some time ago the window lifter on the driver’s side failed to me, shortly afterwards the one on the passenger side. short time later the one on the passenger side went again and a day went even on the driver’s side. meanwhile it is the case that the one on the driver’s side does not go and he goes on the passenger side shcon for about a month. I was already working with it. switch and cable etc. we’ve looked at everything and we’ve got it all. it’s also coming to power with the fensteheber engine. so actually only the engine can be broken. but why the devil, does it go sometimes and sometimes not? and where do I get such a motor. I’ve already looked everywhere in the internet, at ebay and so on and at the car parts dealers and the scrapping places near me, but I haven’t found anything. can I also do a normal curling stick in the doors and throw the window lifter out? w är supernett, if you could help me in any form. Thank you!!
