Okay, classic case of trying to fix one problem and causing another.... My rear washer has never worked on my car because the spraying jet was corroded. I finally got round to buying a new jet which meant i could clear the back window. All was well for about a 2 days. Then the rear wipe became very sluggish and not wanting to complete the full sweep. After stripping the motor today what has happened is the new jet had not fully engaged with the spraying tube inside the rear wiper mech. As a result every time i sprayed the rear jet water was slowly filling up the wiper gear mechanism and casing. I stripped out the motor, cleaned it out and lubed it all up before re-assembling....... Now the wiper runs all the time!!!! Runs when it's turned on, runs when it's turned off. I'm rubbish with electrics but my guess is i burned out a relay when i had constant power going to the relay but a mechnism full of grease and water. I have remover the fuse (27) and am hoping after a day it fixes its self. Any thoughts on what i have done?? Cheers.
