wingsno19 Posted December 14, 2008 Share Posted December 14, 2008 I have a problem with my wipers that is driving me crazy. Firstly, they go too far at both extremes. So at the top of the swipe, they go off the car on the driver's side. At the end, they slam into the bottom with great force. This causes the wipers to be extremely loud. 2ndly, the wipers speed is fine 80% of the time, but at other times they are extremely slow. Does anyone have a fix for this? Is there an adjustment or do I need a new motor assembly? If so, has anyone done this and is it as simple as bolt-on? Link to comment Share on other sites More sharing options...
KnifeyMcShanker Posted December 14, 2008 Share Posted December 14, 2008 I've never dealt with wiper motors before but I imagine there's a sensor that detects when its at the end of the stroke. That's probably the problem. Link to comment Share on other sites More sharing options...
Osei Posted December 14, 2008 Share Posted December 14, 2008 Don't believe its a sensor, things were not that sophisticated back then. Make sure the driver's side blade is not too long. More than likely the crank arms are bent or have been replaced with the wrong parts. Only things I know of to check. O. Link to comment Share on other sites More sharing options...
jonklein611 Posted December 14, 2008 Share Posted December 14, 2008 motor would be an easy replacement. Should be able to find one cheap. Link to comment Share on other sites More sharing options...
wingsno19 Posted December 14, 2008 Author Share Posted December 14, 2008 My wipers are the correct length. I am not sure if the entire assembly is bent? Swapping motor assembly: does the motor just free-spin or is the gearing part of the assembly (to make them go back and forth)? Link to comment Share on other sites More sharing options...
Osei Posted December 14, 2008 Share Posted December 14, 2008 Open hood and see where cranks attach to motor. There should be an odd shaped cam/bellcrank that attaches to the arms. If the bushing is worn or missing, you will get the erratic operation you're experiencing. Watch the motion as the motor turns. There are plastic gears in the cranks and may have reached the end of their life. Go to www.opposedforces.com , (can't find original poster to give credit). save everthing now. Go to pages part of browser and save that way. Will help in all your future endeavors. Also search under vacation pix for other good stuff. Lastly www.endwrench.com. Hope this helps. O.
