Greetings- Well, not wanting to waste any time testing out the "new" Volvo's rear bumper, my wife backed her 5 day old 2006 xc 70 into a tree, shattering the rear hatch window, but only doing minor damage to the bumper itself. $210.00 later, it has a brand new rear window, along with an unusual problem. The rear wiper will not shut off completely, you can vary the intermittent function, but I can't find a position to completely bring the rear wiper to a halt. Any ideas on where to start trouble shooting? Doesn't Haynes make a workshop manual for this car? Thanks in advance. Paul

 

Nobody else has ever experienced this issue? or are you too bashful to post?

 

Wipers don't really "turn off"; They park. So the wiper motor itself has a set of contacts internally that tell it "stop here". All the other components, the switch, CEM, and rear EM just tell it to kick off when it's in the park position. I would expect to find the problem internal to the wiper motor assembly. You can troubleshoot that easily enough if you want to (I would) and I would look at the wiring diagram. volvowiringdiagrams.com does have that for your car. 41 megs, 328 pages. they are difficult to understand, I have to admit.
