: : power windows won't stay in full up position on my new 430 CLK. Any suggestions as to how to re-boot the comp[uter that runs them?<p><p>Put them down, then tap them up and hold for a few seconds in full up position (with door closed). This may re-set them. In my 430 cab, the windows were very slightly out of alignment once adjusted by the dealer (both sides) problem apparently solved. Computer apparently thinks there's an obstruction and due to "no pinch" feature, drops windows down. The owners' manual describes re-booting as well, or call 800 number. Good luck.<br>
