Jono Posted October 7, 2005 Share Posted October 7, 2005 I've tried a lot of approaches to get rid of windshield wiper chatter on my '92 SC400. The chatter does not happen when the windshield is initially clean but after only several miles in rainy conditions, the wipers start making noise. Here's what I've done but none of them have made much of a difference: Tried various brands of wipers blades: OEM and aftermarket, including teflon coated Replaced the wiper arms with new ones Installed a new windshield (previous one needed to be replaced anyway) Used different windshield cleaning and polishing products Tried several Rain-X type products Teflon window washing fluid About the only thing I haven't done yet is the wiper motor and linkages. I've searched many websites that deal with this subject and I'm out of solutions, and frankly exasperated. Any suggestions out there (other than getting rid of the car) ???

DomLee Posted October 7, 2005 Share Posted October 7, 2005 Have you checked to see whether the wiper arm itself is warped/bent? This happens when you have the wiper arm up...and then proceed to open your hood. The hood will hit the arm...and either hit it back or possibly bend the arm. I accidentally did this on one of my cars. You might also want to check to see that the wiper arm is firmly bolted in place. Look for the nut at the base of the arm, as it may have loosened over time. Quote Link to comment Share on other sites More sharing options...
SKperformance Posted October 7, 2005 Share Posted October 7, 2005 Odd to go through all that and still have chatter. My wife gets that on her car but she never washes it either ,so it is her own fault. I used rainx and oem Lexus wipers and all my noise is gone completly.

Jono Posted October 7, 2005 Author Share Posted October 7, 2005 Thanks for the responses. The arms are straight and the bolts are tight. Although I haven't opened the hood while the arms were up, I can easily see that happening. I have the old wiper arms so I'll experiment with various spring tensions. (not sure how since they're not adjustable but I'll innovate) Quote Link to comment Share on other sites More sharing options...
