Nifty Posted July 12, 2009 Share Posted July 12, 2009 As title says I've just replaced the wiper cable and drive unit after it broke, almost a couple of years ago, and thus I went aero. Neither the wipers nor the washer pump wants to work when the relevant switches are pressed and ignition is on. Wires all appear to be attached correctly. Have checked fuse and it appears to be OK. Have even switched it with another 15A fuse which I know is working but still no life. I am desperately short of time to get these fixed before I go to the Dales in a week's time and need to have the windscreen on. Any ideas please? ======================================== Keep off the straight and narrow 😬 Link to comment Share on other sites More sharing options...
SV Gary Posted July 12, 2009 Share Posted July 12, 2009 Nifty If you have tightened up the windscreen rack tube clamps too tightly it can clamp the rack in the tubes and stop the wipers from turning - as for the washers The lead dog always gets the best view.

Mick Day Posted July 12, 2009 Share Posted July 12, 2009 Try Gary's suggestion 1st. Did the wiper motor & washer motor work before you removed the bits? If the wipers still don't work you need to get back to basics. Is there 12 volts present at the washer motor? Check the earth? Do the same for the wiper motor as well.

Nifty Posted July 12, 2009 Author Share Posted July 12, 2009 Windscreen wiper switch light isn't coming on when the dash lights are on but washer light is? Could it be no power to the switch and the washer circuit only works when wipers are on? (I don't suppose the electrics are clever enough that the wipers/washers don't work if the windscreen heater lines aren't connected ) Will be taking the wiring diagram to bed ❗ ======================================== Keep off the straight and narrow 😬 Link to comment Share on other sites More sharing options...
rj Posted July 13, 2009 Share Posted July 13, 2009 Nifty, The switches should light up when lights are on, but it's a separate circuit which has nothing to do with the operation of the wipers. /r Link to comment Share on other sites More sharing options...
tweeky Posted July 13, 2009 Share Posted July 13, 2009 have you put the fuse back in the fuse box I took mine out when I went aero didnt want a face full of washer fluid lol Tweeky In a purple haze Link to comment Share on other sites More sharing options...
Nifty Posted July 13, 2009 Author Share Posted July 13, 2009 Might just be that the light has gone in the switch ? Haven't had the wipers functioning since I swapped the engine so perhaps I rewired the switch incorrectly when I rewired the ignition. Is there a feed from the ignition to the wiper and/or washer switch 🤔 ======================================== Keep off the straight and narrow 😬 Link to comment Share on other sites More sharing options...
Nifty Posted July 13, 2009 Author Share Posted July 13, 2009 Tweeky, All fuses appear to be correct and whole. ======================================== Keep off the straight and narrow 😬 Link to comment Share on other sites More sharing options...
Nifty Posted July 14, 2009 Author Share Posted July 14, 2009 With grateful thanks to Ernie giving a lending hand we managed to track live power down to the wiper control unit but nothing coming out the other side to the motor. A quick chat to Lucas confirmed that the wiper control unit, a Lucas 6DA, is obsolete However, Mick and John at Redline told me to bypass it and hey presto I have an active wiper motor. Believe it or not the washer pump was also broken and that part is also proving to be a sod to find. However, on Redline's advice I've bought a "fit all" pump and will connect it in series with the old one (which is required to fit into the aperture of the washer fluid reservoir) and just draw the fluid through the old pump body ======================================== Keep off the straight and narrow 😬 Link to comment Share on other sites More sharing options...

Nifty Posted July 14, 2009 Author Share Posted July 14, 2009 Managed to locate and purchase a replacement wiper control unit from Rimmer Bros -£33 + VAT ..... then came home and found one on eBay for £6.50, secondhand but assured it's working by the friend chap on the other end of the phone. Might have to find a heartbreaking excuse to return the new one to Rimmers for a refund *redface*p] ======================================== Keep off the straight and narrow 😬 Link to comment Share on other sites More sharing options...
