2021 Silverado Windshield Wipers - wacky, intermittent!!

[ChevroletSilverado]

Hello everyone,

I’ve got a 2021 Silverado 1500 LT, 5.3L … My windshield wipers work fine in the first couple slowest settings, not at all in the middle settings, and intermittently in the fastest setting. At the fastest setting, sometimes they come right on, if they don’t, I hit my turn signal with the fast setting on and immediately they take off(that’s only for the highest setting, the others either work fine, or not at all). Any ideas???

I will also add that they never get stuck straight up, they always return to home. When they do go they seem normal and full strength, it’s getting them to turn on it seems.

since you have some lower speeds and high speed that probably eliminates the under hood fuse block. could be wiring, but probably is the switch. i had to replace mine because it would turn on the left signal and would not shut off

I have an identical truck (year, model, engine, trim), and I’m having the exact same issue. Did you ever find a solution?
