Several Toyota & Lexus vehicles find themselves with a broken power seat from time to time, and the most common causes of these are missing white caps, and stripped gears. The white caps can work themselves out of their little housing through use, and once they fall out continued seat use will damage the gear inside, since missing cap has made the shaft and gear inside no longer in alignment with the worm gear. To see if you’re missing a white cap, just look under your driver seat from outside the vehicle, towards the front of the seat. You should see the little cap threaded inside the gear housing, shown below. If you see a hole, then voila, you need a new white cap. To inspect the passenger seat the seat must first be unbolted and tipped back, as the cap is against the transmission tunnel.

Originally developed for 1993-1997 Toyota Land Cruisers and Lexus LX450’s, these parts have been known to also repair the Supra, Solara, 4Runner, and other vehicles made in the 1990’s by Toyota, including the Granvia and Crown Majesta!
