02Envoy wiper chatter

My 2002 Envoy Windshield wipers chatter in Delay mode only.

Try cleaning the windshield with glass cleaner and wiping the wiper blades with rubbing alcohol.

Recall for wiper motor issues had the same thing with my 2002.

I can check to see if there are any open recalls on your vehicle, if you like. Please send me the last 8 digits of your VIN in a private mesage.

Clean windshield/wipers is not the issue. Tried this first, then replaced wipers and still have the problem. Maybe my explanation should state herky jerky movement instead of chatter.

I was thinking that I had heard of this recall before, I appreciate your help.

Good morning,
At this time, I do not see any open recalls associated to your vehicle (the windshield wiper motor recall has already been done on this vehicle). Please let me know if I can be of further assistance.

Yes. There is a big difference in those two. Chatter implies wiper blade is sticking to windshield. Herky jerky implies a motor issue. More info, is always better.

You can always try a used, cheap junkyard wiper motor to see if the result is the same. I always try the cheap scenarios first.

*" The contact wheel inside the gearbox is covered with grease, and caused intermittant contact, which causes the stutter. I cleaned mine after reading about this here 3 years ago, and its been fine ever since."
