Why might my rear wiper blade have stopped working?

It will need to go into the shop is my guess. I rarely used my rear wiper so it would not be that horrible to have to do without it for a while. Your vehicle may actually need the rear wiper. If you think it may have stopped working due to not having a blade in it, call a dealership and ask them or check your owner manual.

i don’t know where you live but sometimes they get frozen in the winter and when turned on the motor gets damaged. I paid $90 to have it repaired. GM Minivan.

Check the fuse….. if not chances are it’ll be the rear wiper motors blown, or as an outside chance, the switch.

I am with @worriedguy , check the fuse.

If when you flick the switch you hear the click of a relay from somewhere near the fusebox then the fuse, switch and relay are fine and it’s probably a motor fault. If you don’t hear anything, then it could be any of the above.

..ok…where’s the fuse? and where is the fuse box? I take it they are the same thing?—maybe I should get someone to look at it!! x

Sorry @lynneblundell! It’s usually under the dash of a newish car either near the bonnet release or in the opposite corner. It may be hidden behind a flick off panel. Can you hear any of the noises listed?

I haven’t tried yet…. will do tomorrow! Thanks @OreetCocker

There may be a web site that can help you out, A forum for the make & model of your car, I have a VW & a Vauxhall, if I have any trouble I post questions on either related site to get assistance, usually from very helpful people who know their stuff, check it out there may be one for your car! ? :-/
Good luck!!.....

@lynneblundell. No worries let me know how you get on :-)

The first thing you have to do is determine if it is getting electricity. A fuse, like others said, is the most likely cause. If the fuse is good, is the electricity getting to the motor? Can you hear the motor attempting to move? If the motor sounds like it is turning, the problem could be the linkage or other mechanical problem. If you are mechanically inclined, you will have to expose the mechanism and see what is bound or broken. If you are not so inclined, the car will have to go to the shop.

fuse, turning mechanism, there’s a few parts that could be messed up. I don’t know enough about wipers to diagnose this problem :/ hope it turns out alright.
