Just bought a 2013 GS350 and saw some weird things with the wipers, want to make sure this was a "feature" before I take it to the dealer. My apologies if this is a common problem that's been hashed out a millions times here.

For one thing, it doesn't seem to want to finish a full cycle. When I hit the stick up for a single wipe, the wipers will only move for as long as i hold the stick up. If i let go, the wipers will stop at the top of the cycle or anywhere in between. It won't return to the home position.

Similarly, if I put the wipers on continuous, if I turn it off the wipers will just stop wherever they are on the window, instead of returning to the home position.

Also, if I hit the sprayer, the wipers won't start wiping, i'll have to manually turn them on (and then run into the issues mentioned above).

Is this a normal thing? Is there some fancy setting that I don't know about? Any easy way to reset the wipers?

 

Mine is a 14 and it definitely completes a full cycle when I push it up. And it also returns to the home position when I turn them off.

 

OP - That is most definitely not normal. Something is amiss. Did you buy the car from a Lexus dealer?

 

Thanks the replies, the car should still be under the factory warranty so I'll take it back to the dealer. Unfortunately I just had it go through the 20k service so i'll have to take it back there again.

 

I had this same problem. Under warranty so no charge

 

Just took the car in today and yeah, it was the control relay. Apparently this is fairly common, service adviser knew exactly what it was when i described it.

 

I had this issue as well on my 2014. Had to take a video of it cuz I had trouble replicating the issue at the dealership.
