My windows failed last Wednesday. No reaction on either of the 2 switches.
Fuses checked, all was good. Consultation on Facebook told me that fuse 10 was the one to supply windows.
Supply to switches tested, no 12V to any terminal. Check drivers side first as it supplies passenger side and thereby prevents use of both windows at same time. Yes, that’s a feature, not a fault...
ROM consulted. There is a so-called circuit breaker in the supply wire. I guess that is another word for fuse ? Found behind RH knee bolster and tested: 12V on both sides, also with contacts activated.
The only component left in the circuit was relay 221 in the diagram, sitting next to the circuit breaker. It was good to measure and find, that the coil windings was discontinued.
Open relay, find a broken hair wire, solder, test and windows are back in service.
