Intermittently intermittent wipers and stuttering wipers...
My collection of faults, sorry, I mean my 145 had a faulty wiper control stalk and a jerky wiping action which I resolved over the weekend.
I did the job of disassembling the plastics under the wind-screen (what is the name for those???) and then disassembled the motor assembly also. Like most people who do that job, I was surprised by the amount of grease in the commutator plate, and promptly removed it all and cleaned it with a switch cleaner.
On working the wipers, I found that the action had worsened, it was clicky and jumpy and sounded as if there was arcing in the assembly... so I figured that a little grease was required in the assembly. It may sound unusual, but I used a tiny amount of copper grease for two reasons... It contains copper, which is softer than brass or steel (what the armature/pickup and plate is made of) and will act as a type of lubricant. And it is also a conductor. When it's in it's normal state, ie, direct from the copper grease tin, it's non conductive as the copper particles are insulated from by the grease. So this eliminates the chance of a short in the module!
I also cleaned the contacts on the control stalk, these too were flooded with grease, causing the intermittent intermittency.
I now have working wipers for the first time since I bought the car!
Now another option would have been to use graphite. It's a great high pressure lubricant, but must be suspended in grease to be of any use. Otherwise it flakes off...
So, add that to the list of 1001 uses for copper grease!
