Had the same problem twice on my 2005 Sequoia. Rear window, wiper and defogger all dead. First time it was repaired under warrenty (29,000 miles) about a year ago. This time I have 45,000 miles (althought only 29 months old) and the service center quoted $650 to repair, at my cost. Both times they say the window motor shorted out and ECU for the window shorted out as well. That part (the ECU) alone they quoted as $219. I did not get it fixed. I read through the Techncial Service Bulletin EL007-06 and it sounds like a lengthy process, especially drilling out the rivits. However, from reading above, it looks like the process will fix the root cause. I'd like to know if anyone has approached Toyota with this common design flaw issue and had a positive response from them, i.e., they would help defer the cost of fixing their design error.
