Hi everyone, I've got a 2004 C-Max manual 2.0d, which I love, but I'm having problems with the reverse sensor. The trouble is, it has stopped working, my Mrs usually drives it and she told me recently that she could just about hear the reverse alarm, but of course now it has stopped completely. I have wd40'd all connections, to the sensors, control module etc. The module says Ford on it. Reading other posts, it was mentioned about fuse 84, this has been checked and is fine. Reversing lights all work, and all wiring seems to be in order. Is there a way of checking the sensors? or have I missed something obvious. Just though I'd ask, before I bite the bullet and take it to a robbing thwaite. Help please.
