Hey, I did a bunch of searches so hopefully this hasn't been answered before, but I've noticed my windshield wiper ams don't reach their lowest position, except when at full speed and I've discovered that's only because of momentum, as they have about 25 degrees of free movement, or play. I haven't found anyone else mentioning play in the many posts talking about their wipers not returning to home. Does this level of play mean a worn bushing or something broken in the linkage? Thanks for any assistance! Cheers!

 

The wiper transmission may be worn out, yes I thought it was called the linkage etc but it is actually named the transmission. You can verify by taking your cowl cover off and take a look see where the motor hits the assembly, I tried to track one down but I believe they are discontinued and had to go to a yota yard. My wipers were going down too far and just kept getting worse. Although you may be able to get something aftermarket.

Once you get the cowl off you can temporarily put an arm back on and move it a bit and you should see slop in the assembly.

 

Appreciate the help. So I checked it out, and the only slop is actually where the linkage meats the motor. The bushing does fit firmly on the motor arm ball, but doesn't seat securely against the linkage so it just moves around freely. I found this rubber boot which has split, down in the gutter area of the linkage compartment. Seems like it might be meant to hold the bushing against the linkage?
I've tried attaching a short clip of the slop I'm talking about.

Fished this little rubber boot out of the linkage compartment under the cowl. Seems like it might be meant to hold the bushing to the actual linkage? Without it the bushing while pressed onto the motor arm just moves around freely.

Slop at the interface between motor arm and linkage. Due to the missing boot I found?

 

Yup, looks like mine, the hole is bored out from the play. You’ll need a new tranny Have you been able to find a source for the part?

 

I don't think the hole is bored out actually as the bushing seats in it perfect, it just wasn't secured. I removed the hole assembly from the compartment, removed the arm from the motor after making sure to mark it's position, cleaned up the torn boot, filled it with grease, and seated the bushing and boot onto the transmission, pushed the ball into place, and used self fusing silicone tape to wrap the boot, essentially making a new boot. Got it all reassembled and it's working perfect now! No slop. Saved $170.

Hmmmm maybe I’m not remembering how mine was trashed, mine might have been further gone, I swore there was another piece of plastic on the other side of the white bushing that presses in that hole in the vid, I could be wrong though it’s been years glad you got it sorted on the cheap!!
