Pontiac Problems? Ask a Mechanic for Answers ASAP
In the body harness, left side of the vehicle, approximately 14.5 cm (5.7 in) from the left power seat breakout
THis is under the rear seat, #3 is the connection.
I see that one #3, it also appears to be a grounding block. That looks good. The splice you reference in the original answer I don't see(the one you show under the drivers seat).
I find it hard to believe there would be a pinched wire in all the doors at the same time. So I really want to check that connection whereever it is.
Please stick with me on this, if we can pull this off, I am willing to pay your bonus whatever you would like that to be.
IT could be a single one of the branches that is grounded.
THis splice is not under the drivers seat, it is under the rear seat by the rear fuse block.
What I would do is get the splice apart and then find the branch to the drivers door. With it on, connect one branch at a time to see if one of the other doors works. The one that does not is the area to start looking.
OK, I have to appoligise. I made an error. I was looking at a splice pack sp302 not splice s302. What we are after is in the picture below, #4. This will be in the harness behind the drivers seat.
