mrbrain i tested continuity from as far as the b pillar it goes into the frame from there but idid have continuity from that ground point to the plug for the seat switch i also tested from the main plug under the seat to the seat plug and it looks good when you say trace the ground path what path is...

regent here s the newest thing if i back feed a wire from battery ground into either of the 2 motor wires the switch will operate until i go to operate the back fed motor then the fuse will blow do you think its ground related im getting close lol

thanks for the schematics but does it matter that the pass seat is manual

im a little stumped i have a 2004 s40 2.4L in regards to the D/S power seat I checked fuses all good i have what seems to be a good switch only because when i take the plug off the top of one of the motors and put a tester to it i get 12v so the motors are getting power the strange part is if i jump...
