We pulled a front passenger  door from a 2009 IS250  to put on our 2007 IS350. The window motor sounds like it is trying to lower the window but only makes a muffled clicking sound.

Any ideas? We tried the battery disconnect reset procedure. 

Check to see if your  reverse lights are out.  The horn shares a fuse with that.  Probably not but worth a try.  

For a few bucks you could bypass the steering wheel horn and mount a horn button.

Thank you for this post.  I was having the exact problem with the 2000 LX470  I bought this morning. After reading your post I checked the tires and added about 20PSI per tire and problem went away.  What was remarkable was that i was able to reproduce the problem every single time on an S curve in my neighborhood.

I am the second owner

Paid $2000 inAustin Tx

l have owned it for 45 minutes

I bought he car knowing it needs some work.  Right front ABS will engage . I am hoping it is only a wheel sensor.  Any thoughts?
