Rear Wiper Motor Not working

Postby D366Y » Sun Apr 09, 2017 5:10 pm

Hey chaps, (and Chapettes)

My rear wiper motor has always worked fine and never had any issues but since about two/three days ago it just hasn't come on at all when I press the button.

I referred to the bible (Haynes) and as part of diagnosing the issue it said to check "the gearbox cover and gear assembly for damage"

Pardon my naivety but why am I checking anywhere near the gearbox for my rear wiper motor?? I am stumped :headscratch:

any help/advice would be great!

Thanks

It will mean the gearing mechanism for the wiper motor.
Before investigating anything like that I'd find the live wire under the cover that lines the tailgate and see if it has current when your dash switch is on. It could just be a bad connection in the switch - or a fuse. Is there anything else that's not working?

Thanks for the quick reply Peter; All the fuses are still in place and don't appear to be broken and I tried John's tip of moving them all as well just to roll them around a bit to see if it was a dodgy connection but no luk, and so far there is nothing else I've noticed that isn't working apart from the reverse lights but that's because the wire isn't plugged onto the connectors on the gearbox.

What would the best way to test the live be? I've taken the wiper cover off and it all looks brand new under there, disconnected the two clips (look like the same connections as the front speakers) and it all looks to be a good connection in there?

Thanks

Is the connector clean where the tail gate meets the bar above the lights where to boot catch is ? That springy black thing is a earth I believe ? I once sprayed mine then my wiper didn't work worth a try

Thanks for this, will have to try over the next few days when I get a chance to check, had to put the glass back in the passenger door after my dad accidentally pulled it out of place and it dropped into the door earlier so ran out of time tonight :doh: :lol:

As John says, I'd be checking the tailgate switch also.

Hi buddy,

Depending on the model it could either have one or two switches, one is for wiper and the black button type is for the boot light if fitted, everytime I have had issue's with the wiper it's normally dirty contacts on the switch that's located on the passenger side, a gentle rub with sandpaper should do the job :)

No not yet! I didn't get a chance to try it yesterday, I did check the contact you mentioned, and noticed it was quite dull, scratched it a little with my keys to see how bad they were and loads of shit started to come off! It was pretty shiny underneath all that crap so will have to try that when I get a chance, might be later this week or over the weekend.

Also how would I go about checking the switch itself?? It still presses in and clicks?? :?

Cheers

You can get to the switch but taking off the dash trim under it you should be able to unplug it and push the switch out from there (push it out towards you), or you can take the fascia off too if you want to be thorough, though that means taking all of the lower dash trim off, and if your fascia still has the metal clips on the top holding it in, you'd best loosen off the steering column and drop it down a bit to allow you to pull the fascia out from the bottom to avoid scratching the top of the dash with the metal clips.

Thanks guys, I know how to get it all off without a hitch as I took it all out the other day to check the switch but other than it still clicking is there anything else to check??

Got some sandpaper on the earth contact point on both the bootlid itself and also the button like thing above the rear lights and gave it a quick rub, problem solved
