Hello, I have a 2017 Silverado. It was 41k on it so just out of warranty. The wipers quit working. When you lift them off the windshield they work great. Lay them down and nothing. I’ve replaced the blades, motor, and the top of the fuse box pannel. After 3 days of trying everything I can think of it’s at the dealer. Hard to believe they can’t / won’t help me with this as new as it is. Anyone have any similar issues with 2017 wiper blades? I’m sick over it. Ready to be done with chevys . They are all I’ve ever bought since I was 16. But crap like this leaves a bad taste

That's bizarre but, it's a computer controlled mechanical item so unfortunately cars can be really infuriating these days. I am not surprised that the dealer isn't willing to work for free, they get paid for warranty work by GM it's not something they just provide to you... Sorry your having issues but, I think your expectations are a bit amiss about the dealer 'helping' you... I do find it disappointing  that the wipers aren't working on such a new truck though and I hope you can find a quick cheap fix..

The puzzling part is that they will move if lifted from the glass, but not when down.

There isn't a sensor that tells them if they're lifted or not, it's purely mechanical there.

If you turn the switch on while they are against the glass, have you tried helping the motors along by trying to move the wipers by hand?

My only other guess would be that there is a short somewhere, reducing power to the wiper motors such that they move under essentially no load and won't when one is applied.

You said you replaced the motors. I would try this.

Take your old wiper motors and cut off the pigtails. Strip a little insulation off of the wire ends.

Plug these into the truck, and use a multimeter to look for power when the switch is turned. You should see 12-14V pulsing at the frequency of how the wipers would move. If you're seeing good voltage, idk what to tell you. Something is physically sticking the blades to the glass.

If you're getting low voltage, you have a short somewhere sapping the power.

      What did you do to your "other" car (aka musclecar) today

      Even tougher is the 5.0 / 302. That's what this one has.    https://postimg.cc/Z9XRrCSg   https://postimg.cc/4n3F3yzY   Just realized I had the airbox removed in the engine pic, lol.

      Yep! This should be a pin somewhere as @pgamboa really dives into all of this. Thanks for reposting the link!

      I did the new thermostat after doing a 'flip' for a year. Runs as cool one way as the other in the summer but in the winter there is a bit of a floor. Yellow with the new 70 C thermostat. My data over the life of the unit to date. Still need more cooler. Anyway that floor helped both winter fuel economy and shift quality in the winter. I found it a good balance.

      Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.
