Hello,

I have isolated my issue with heated seats, blower moter etc. to a probable ground wire issue, but I'm having trouble finding the 4 locations I'm after to check. On the wiring diagram, they are listed as ground zones 10, 11, 12 and 18, and appear to be somewhere near the left and right front door pillars, and near the pillars between the front and back doors. I've got the front seats out and a lot of the trim parts removed in that area, but I can't seem to find the location of any of these grounds. Can anyone help?

Roxie, with them calling out zones are you sure you're looking for a ground and not a common wire to those zones? I don't have those drawings but sounds like u might be searching for the wrong thing. That wire would not be bonded to the frame or body like u might think. It may need to go back to a common buss. Check the drawing a bit more, if truly a ground then bond it to the frame or pillar with a fresh attachment point.

I've tried to upload the diagram, but no luck. I did however find a link to it. Its on page B16 in the following document:

I guess another way to word it, would be that I'm looking for the ground location for the front blower motor, and the heated seats.

Ok, after scanning the drawing of the ground zonnes (that's all I looked into) it says that all but zone 18 are dirty grounds or tapped at some point to the engine-body-bed-or elseware. Zone 18 is clean and has to be connected back to that paticular buss. find your drawing of the circuit you are looking for, find the color of wire you need for the common and trace it back to see if you have continuity. If you do redo your connection, check again for continuity, if none, try providing a jumper or new wire back to that common buss.
