Help please with non-functioning wipers.
Discussion
Hi all.
So, on the A1 the other day, my windscreen wipers decided to give up the ghost halfway up the screen while wash-wiping. I've had no sign of life from them since. First port of call is to check the box out in the passenger footwell. I knew it had gotten hot at some point as it was noted at the last service. The plastic box has become so distorted due to heat that the whole thing resembles a football rather than a rectangle box. However, on taking the box apart and looking at the circuit board, all seems well. I took some photos.
As you can tell, one pin has discoloured slightly, so I cleaned that up with a bit of emery cloth and plugged it back in this evening. Now, when I turn the ignition on, I can hear relays clicking in the box when I press the wiper buttons on the steering wheel. Does this prove that the box is still ok, or is it not that clear cut? For what it's worth, if there's any link between the wash wipe button and the control unit, I'm still getting water out of the washer jets, just no movement from the wiper of course. Does this link to the motor? If so, how could I test this?
Cheers.

I would try lifting the wipers up as if you were washing the windscreen and try them. I bet they will start moving no problem. Mine have a habit of sicking if it is only very light rain or dry , I have seen this on other cerbs. The Motor is not really up to the Job it is from a Classic Mini after all. A car with one of the worst wipers i have ever seen.

i might be wrong on this Rob.... but isnt this fault common to when the wiper park switch fails ?
When my park switch failed, it didn't stop the wipers from working, it was just that when you went through the cycle of turning them off, when you pressed the button for the last time (i.e to stop them) they stopped at exactly the point when you pressed the button i.e most of the time half way up the windscreen...Hi,

The park switch is a nice cheap and easy place to start.

Hi Robsco, check out the wiring for the boxes in the manual (availableon one of the sites, can send link if required).
Mine started wth park not working properly (would stop at randem places) then stopped altogether. I had failed connectors in both the boxes in pasenger footwell. Once I got the wiring diagram it was pretty easy to trace fault, see if wipers work when you connect power to one of the signal wires first. I had burnt out connectors plus a dodgy intermittent connection in steering wheel which caused me a headache for a while.
My motor had faield previously so I guess had shorted the whole thing causing the damage.

Update chaps.
I borrowed a test light from work today and checked the 5-pin plug coming out from the bulkhead and into the wiper motor. All seems well, different pins receiving current when different buttons are pressed on the steering wheel (good bright bulb too, so no wiring issues). The only pin that didn't light up at any stage was pin 2; is that unused? That would suggest that the motor is the problem, non?
