Hey everyone,

I have almost finished putting my rover column and rover wiper motor into my clubman van. My question is this.

The wiper motor works from the column stalk and I have intermittent, slow and fast. The problem I have is that the motor runs really slowly. What does this usually signify? I have it earthed from the body of the wiper motor and also from the black wire coming out the back. I think this is correct but wanted to see what you all think.

I have installed it but not attached it to the tube, wheel houses or any of that stuff so its not this that is slowing it down.

The wiper motor is new and a rover one. The column is a rover one out of a late model mini (we don't have rovers here in oz, well many)

I thought maybe the extra earth was the problem but it isn't

I tested the voltage and it is getting about 11.5. Should this be more?


Thanks in advance guys, looking forward to hearing some ideas as I have no idea.

Cheers
David

11.5v is a bit low, but should be fine. Have you tried charging the battery or running the car if possible and see if that makes a difference? Also, check the condition of the original wiper multi plug as they can be corroded and cause a high resistance which in turn reduces the efficiency. If the plug is corroded, Mini Spares etc sell repair looms which you can solder in. I take it the wiper motor came with a brand new park switch too?

Hey Mate,
Thanks for your fast reply.

My mini is a clubbie van and it had a 2 speed wiper motor that had a dash switch.
I put in a rover column so I can have the controls on the column and put in a rover wiper so I can have the intermittent etc.\

What I have done is used the existing wiring that ran from the old motor to the dash (its a brand new loom anyway) and added to the wire to make it reach from the dash to the new column. Could this be the problem? Im stumped.

Cheers

Could possibly be where you've extended the wiring then, how were the connected, did you solder the connections?

Hey Black Tulip,
Thanks for the reply.
the motor is running slow whilst not attached to the tube, wheel houses etc.

Hey M44k,
I used connectors to connect it. I was going to solder it once I knew it worked.

Maybe I will test the voltage at the column to make sure that the voltage it at a good level before the addins maybe. Any other suggestions?

When I swapped mine over to MPI stalks, I fed the lights through relays so no heavy current was going through the stalk/switch, I think I did the same for the wipers too. It could be that the stalks aren't up to the job of powering the wipers due to the relativity small contacts within the switch itself, it might be too much current for them to handle? I'm just guessing now though.

Hi again,

Its weird as I bench tested it all and it all ran fine and really fast so not sure. I will have another good look next weekend and get it working.
I think it will be worth it once I get it working. Controls on the stalk... much better.

Youre overlooking the wiper motor brushes, cheap and easy to change, theyre something that wears as the motor is constantly turning against them.

My money is on those

[M44K TS]

Brand new motor though I think.

[Carlzilla]

just read again, sorry

if the motor was working fine just on the bench test, id take the wiper rack apart and regrease, and check for any resistance, there should be very little
