I can't seem to figure out what has gone wrong with rearview mirror. It was working a couple of weeks ago. I have a bessacarr e452 and the sergeant unit doesnt seem to show off there's a fuse for this. Could it be somewhere else?
Any help appreciated
Kind regards

So is it a wired one or wireless?

It will have a separate fuse/s either way.

Does the screen turn on? Mine has a switch to change cameras V1 & V2

Where does the camera get its feed? Usually, the reversing light wire if aftermarket; if part of the actual build it could be from the gearbox switch.

Where does the screen get its feed?

Follow the wires back, and there will be a fuse/s.

Do you mean the reverse light feed, otherwise it would only come on every time you braked

A bit more information about both the unit and the nature of the problem might be helpful.
 
Probably not the case here, but we had a similar issue when we took delivery of our van. The dealer couldn't fix it and, because I'd declared the camera system on my insurance, I was not prepared to take delivery if it wasn't working. After some time had passed, Jan noticed a decal on the side of the screen that said, "Touch Screen". "Has anyone tried touching the screen?" she asked. Everyone looked at her like she was talking a foreign language and the dealer's mechanic said, "That just means you can change the settings by touching the screen -- touching it won't turn it on!" Then some famous last words as he said, "See...", and touched the screen, which promptly sprang into life! ... Grasping at straws, but I wonder!
 
Make & model would be useful

Plus
Is it standard fitment ?
Did a previous owner fit it ?
Did you fit it ?

Is it the screen that isn't working.
 
Thank you for all your help. I will investigate more. Had to cancel our weekend away as can't drive without rear view mirror. As it happens my wife was unwell the night before so couldn't go anyway.
Love the comment about just touch the screen. Have tried that but nothing.
On that note in my car the electric windows on 3 of them (not the drivers window) wouldn't work. I thought it was a fuse or something was broken. After 3 months when it began to get warm and i hadn't done anything about it My wife had the sense to ask have you locked the windows using the button? Oh I said... yes and hey presto the windows started working. Doh.
 
My rear view camera stopped working about 5 years ago, but I never used it anyway, as I have spent a long number of years driving vans without any rear windows or cameras I much prefer to use the two outside mirrors,
If I am not 100% sure what is behind me then Helen will jump out and watch behind me.
Although a couple of years ago I did fit some parking sensors, so that I can hear how close I am getting to things behind me
 
I only turn ours on if reversing, it's a dual camera one back and one down, but the door mirrors show 90% of what's behind you anyway, until recently most commercial vans didn't have any camera, so no reason not to drive it really.
