shotrock Posted March 23, 2012 Share Posted March 23, 2012 My rear wiper stopped working today so I have taken off the door panel to get at the motor. There are two plugs onto the motor a three pin and a two pin. Does anyone know what each plug does. There appears to be power going to the motor and I can hear a noise in the motor and the lower section gets hot. Knowing this I took the motor off the door and when I turned in over water came out of the motor section. So I am assuming the motor is knackered. Would you agree??? Does anyone have a diagram for the wiring to the rear motor?? Any yes I have checked the fuses etc. Shotrock Quote Link to comment Share on other sites More sharing options...
western Posted March 23, 2012 Share Posted March 23, 2012 wiring diagram below, some of the wires are for the heated rear screen. a new or known good motor will get it working again. parts book page attached too.

shotrock Posted March 23, 2012 Author Share Posted March 23, 2012 Cheers Western for the diagrams. When i took the motor body apart, two magnets fell out. Am I right is saying this should not happen as they should be stuck to the motor casing... Shotrock Quote Link to comment Share on other sites More sharing options...
western Posted March 23, 2012 Share Posted March 23, 2012 I haven't taken one apart, but don't think the magnets should fall out. Quote Link to comment Share on other sites More sharing options...
nickwilliams Posted March 23, 2012 Share Posted March 23, 2012 No, the magnets should not fall out, but they are only held in with glue to hold them in place during assembly of the motor so the fact that they have come loose does not necessarily mean the motor is knackered. So long as there isn't excessive corrosion in the motor then you can probably get it working again once it's been dried out. One thing to look out for is that the shaft which goes through the back door can seize up. Re-assembly with lashings of grease should help to keep the water out in future. Nick.

cackshifter Posted March 24, 2012 Share Posted March 24, 2012 Water comes in down the wiper shaft and runs through the gearbox, drops down through the motor and collects in the bottom bearing on the motor. It's a great design - not. It needs some sort of drain. I spent ages playing with one then gave up and replaced it. Good thing is they all seem to to be the same, even the latest. I think it's a good idea to use it regularly to dry it out. Quote Link to comment Share on other sites More sharing options...
shotrock Posted March 24, 2012 Author Share Posted March 24, 2012 Thanks for everyones help. I used Araladite to glue the magnets back into the casing and gave the rest a clean up. Plugged it all backup and IT WORKED!!! So again thank you.. SHOTROCK Quote Link to comment Share on other sites More sharing options...
