RX400h rear wiper.

Just had a right royal battle with the rear wiper motor, the wiper blade had been juddering and noisy for some time so I took the arm off and ran the motor, what a racket. I removed the motor which took some effort as the window bush had rusted too but I finally freed it. That little motor is really powerful, I removed the cover to expose the gears and I couldn't turn the spindle. I finally removed it and cleaned off all the rust and then rebuilt  and fitted the motor with a liberal coating of marine grease. The moral of this story is that if your rear wiper is noisy and judders don't leave it too long before giving it a coat of looking at, it may save you pounds as a new motor will not be cheap.

Hi there, I think I have the same issue with my wiper motor. Did you get to it from the outside? Or did you have to remove the cover inside the boot?

After a few recoveries via WD40 mine has finally seized up totally.

Can anyone recommend a good replacement?  I don't fancy paying the thick end of £300 for one off Lexus!
