Parrformance Posted February 22 Report Share Posted February 22 I am not looking disparagingly at the wipers, being homeless and all. I just want to do my part to help them find a loving home. I need to turn the wipers on, wait till they get close to the home position, and quick turn them off. If left to their own devices they will stop wherever they damn well are when you switch them off. Might any of you successfully navigated a repair for this in a Volvo, with the Volvo D12 engine? Quote Link to post Share on other sites

Jaydrvr Posted February 22 Report Share Posted February 22 On my '99 Volvo, the wiper transmission drive doesn't lock onto the wiper motor, so that it can break away under load. The drive arm has spines, but the tapered motor shaft doesn't. If it slips, you can just loosen the nut, re-center the arm and re-tighten the nut. I actually replaced the motor unnecessarily to find this out. Not sure about other generations. Jay Quote Link to post Share on other sites

Parrformance Posted February 22 Author Report Share Posted February 22 Wipers are working fine, except they do not return to the down position upon canceling the wipers. Quote Link to post Share on other sites

Shawn Patterson Posted February 22 Report Share Posted February 22 My experience on cars having this same problem is that it typically is a result of a failure in the park circuit of the wiper motor itself. Looks like they run about $160. Quote Link to post Share on other sites

Jay With what you describe as the breakaway system, the wipers would still park reliably, just not at “home”. When you can’t get the wipers to stop at all, or just a very short window, it is electrical, typically in the motor as that is where the park switching usually is. Either way, beats my old Freightliner from years past. Air wipers with intermittent function. Some days they worked and some days they didn’t. Quote Link to post Share on other sites

I've experienced the random parking wherever it wanted to, so I suspected the motor. One time, it wasn't the motor. Sometimes you're right, sometimes you're wrong.

Parrformance Posted February 23 Author Report Share Posted February 23 Sweet, thank you. I have dealt with this since I bought the truck, I will get around to replacing the motor after proper permissions are granted. Quote Link to post Share on other sites
