Perhaps ask in the tech section. My thought with fuses would be it would work or wouldn’t. Sorta working sounds like a problem inside the switch itself. In my general experience.
Good luck.
FWIW, my wipers were totally dried up and split and I found a good coat of rain X and I didn’t even need em. Yes I replaced the wipers but until I did, rain X and the angle of our winshield makes for a pretty good combo in a pinch.
My wipers on my 09 quit working. I can move the lever down and it will wipe one time with the mist function.
I can also use the washer function and they spray and wipe twice. But you put the switch on the delay setting, low, mid or high I get nothing.
Anybody have any idea what the problem is? Is there a relay or fuse that affects this.
Thanks in advance.
John.
