Hi Roverlike.
I have been looking through the fuses diagrams that you so kindly uploaded to the forum, but I have an electrical problem that I just can't fix. So I thought that maybe you can help me??

The problem is this.

I have a rover 45 facelift 55 reg. 1.6 manual saloon. And on the windscreen wash wipe function the water sprays the screen but the wipers do not wipe. Every other function related to the wipers works fine. intermittent ect.
I have had all the relays replaced in the pektron box and checked fuses 18 and 21 which are both fine, I also removed the plastic covers from the steering column and removed 2 multiplugs from the wiper stalk and sprayed electrical contact cleaner on them and gave all the wires a wiggle, checking for loose connections, but all seemed fine.
But the fault is still there!!!!

Do you have any ideas what could be causing this??? or I might have to go to an auto electrician (lots of money)
Any help from you or indeed anyone that can help me will be greatly appreciated!!!

Kind Regards.

Bringe

Hi Bringe,


I read through your problem. Your windscreen wash is not followed by wipe.

Stalk switch provides signal to BCU unit, but after that all following relevant signals are provided by BCU unit. BCU unit provides signal to wash pump, and after that BCU unit should provide signal to wipe motor, which seems missing.
Problem is withoit BCU diagnostic, it is not possible to see why is this happening.


The best person for BCU units is Technozen. He provided very useful explanation of problems with BCU unit here: http://forums.mg-rover.org/how-do-i-answers-common-problems-8/pektron-scu-bcu-384938/


BCU unit is also called SCU unit.



My best suggestion would be to contact Technozen, either on this forum, or on his website: https://www.technozen-electronics.co.uk/

Hello,

Why am I unable to see the pictures you have attached?
I registered hoping to fix issue with the started, but I need to identify the relay so I can check it first before going to repair/replace the starter itself.

Best regards,
Shamoni

I can see pictures in Chrome and Firefox browsers. Pictures are still hosted on Photobucket site, so it is either browser related or Photobucket related.

Hi. Is the starter relay easy to get to, without stripping out too many parts? Having changed the heater resistors to ceramics, the car now won't start. I'm thinking that I may have either blown a fuse or relay?! Has anyone had this happen?
