v40 wiper relay

limpetminer · Nov 10th, 2013, 20:32

My rear wiper has stopped working so i bought a second hand replacement but am having a problem finding where it fits.I took the lower dash cover off but the only relay i can find that looks the same has flasher printed on it.Am i looking in the wrong place?can anyone help.

The relay is actually inside the CEM unit and is soldered on the PCB board

Location of CEM:

This is what VIDA shows for troubleshooting

The relay i have bought came from a v40 & plugs in,maybe it is the wrong one?

Thanks for info i will have another look.

My relay box looks exactly like the one in photo,so maybe it is inside the cem.Is it a matter of just plugging a new one in?also the rear wiper was working inermittently & then stopped altogether so i assumed it was the relay.Do you have any idea what else it might be?

I am assuming that you have a CEM with part number 30896698 or 30859700. Possible causes of your problem:
- faulty CEM (failed rear wipers relay)
- faulty wiper motor
- wiring problem

Thanks for that,have tried changing the motor so will have to get wiring checked & then maybe change the cem which hopefully will be straight forward
