BostonETC97 Posted September 8, 2006 Report Share Posted September 8, 2006 I've read some previous posts, but I'm having no luck fixing my chattering wipers. I replaced my blades with new oem GM wipers, but the chatter still continues. I've washed the windshield with bon-ami, ajax, comet, spray-way window cleaner, windex, rain-x, claybars, simple green, simple green extreme, dawn dish soap, ivory soap, snuggle fabric softener, Tide, Tide with Bleach, and wool-lite. In my last attempt, I even scraped the entire windshield with razor blades. I've tried the rain-x treatment, and come to find it makes the chattering worse after one rain-storm. The only benefit is that without the wipers running, the chattering is gone. I've just about retired my Eldorado to 'sunny days only' due to this problem, and now drive the Jeep in anything but sunny weather. One night I got so irratated by the chatter that I actually sprayed my windsheild with WD-40 (don't ever try this!). What surprised me is that with the WD-40 the wipers were silent, with no chatter or skipping, which says to me the mechanism and motor isn't the cause of the chatter. I've adjusted the angles of the wipers, tightened the arms, played with tensions. I'm starting to think I should just replace the windshield, wipers, wiper arms, wiper mechanisms and motor. Anybody ever find a reasonable solution to this? -Scott Link to comment Share on other sites More sharing options...
BodybyFisher Posted September 8, 2006 Report Share Posted September 8, 2006 Here is the solution, find BonAmi for windows (GM used to repackage this and stopped), the ONLY place I have found it is DO IT BEST HARDWARE See it here http://doitbest.com/DoItBest/Main.aspx?Pag...&SKU=655197 BE CAREFUL, the stuff you find in the grocery store is SCOURING POWDER not recommended for windows/glass! Do a search to see if there is one near you, or order it from them on line! Make a nice paste and using a sponge in circular motion clean the entire windshield. The water will sheet off and your wipers will be smooth as silk... Be sure to clean you wiper blades with windshield washer solution and a paper towel.. Mike My windshield is so clean it sparkles when I use it, it removes wax buildup, tar, road dirt, sap, etc Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
Patrick7997 Posted September 8, 2006 Report Share Posted September 8, 2006 I had the same problem, Boston.... I cured mine by lubricating that hinge at the base of the wiper and getting that to properly move and flex during the stroke.... mine had a little rust there, which kept it from moving.... I theorize that the rust kept it from exerting proper downward tension.... Cured mine. Hasn't chattered since April. Not once. All that stuff on the windshield did nothing for me. Get that hinge lubed... again, my sense of the engineering of the thing is that insufficient downforce causes the chattering... at least in my case. Good luck.
