My rear wiper isn't working. I bought a replacement motor from eBay but its slightly different. how annoying. However I now think that it may be the relay that is at fault.
Armed with my multimeter, it appears there is a constant 12v coming down the wire to the motor when the ignition is on. Surely voltage should only appear when the rear wiper button is pressed.
Does this mean that my relay is faulty? apart from swapping it, is there any other way of testing a relay? Relay part is PRC7404. Dont want to have to pay =A330 odd if its not the fault.
Thanks,
Paul
