So the wifes LWB has lost power to all 4 windows and sunroof. I can push any of the buttons and there are no noises and no actions. Also the driver front seat only moves when driver door is open. Started randomly. Is there a common ground for all of these or?
check the window ICU connection under the cubby. sometimes a little wiggle is all it takes and other times it just fails. it's 22 years old now. the 93 ICU i think should be the same as the 90-92 with just the quick 1 touch on the drivers window. Find someone parting. There is however a ground for the harness that's tied to a 13mm bolt holding the center console to the trans tunnel. Check that too.
Seat adjustment controls tend to fail now as well and are NLA like the window ICU. Mine would occasionally not work (usually after my wife moved it forward) and then it just worked all the time. I think someone retraced some of the circuit board or at least cleaned up some of the connections and got it working again. Check the web. it was someone on one of the US boards.
I forgot to update. The fuse E6 (under the passenger seat) had a plug end pull out. Put in a new fuse and wire pushed out the bottom. Re-installed all works. WOO HOO
