There seems to be one relay, which supplies mirror heaters & back window. There is one fuse for the mirrors (F50, 7,5A?), and one fuse before the relay for both back window & mirrors (F49, 25A?). This can be checked by pulling out the back window fuse, and seeing if the mirror heaters stop working too. If so, it looks like it is a fault in the window. However, if it is a hatchback or estate, there should be a connector somewhere near the tailgate. It is just possible the fault is there, or in the wiring, including the earth wire from the window. 1 Quote Link to comment Share on other sites More sharing options...

artscot79 Posted September 30, 2016 Share Posted September 30, 2016 the plastic trim around the rear window if you pop that off I'll find the connector there clean it up and retry .its all on the same fuse and relay so if mirrors work its another issue the wiring can break where it goes through the grommet Quote Link to comment Share on other sites More sharing options...
