No power to lumbar
Hi Guys,
Ive got a 94 with sports seats here in Australia but the lumbar buttons dont work at all. Both power seats move but not the lumbars.
Now Ive had a good poke around and took apart the centre console switch and it seems there is no power going to the lumbers and/or the motors, by probing with a test light.
Now my question is where does power come from for the lumbers? On the back of the switch I can see the large diamater orange and black wire which powers the power seats and there is power there, but when I probe the thin orange wire on the lumbar control switch, there's no power. Does power come from this large orange wire or do I just need to give this thin orange wire power?
In the FSM I see power comes from the 10A power accessories fuse, but from there to the lumber motors I cant see where power comes from. Any help would be appreciated.

Reading the troubleshooting done, if the 94 seat wiring is anything like the 91 sport seats, you may have a connector or jumper disconnected in the console.
"On the back of the switch I can see the large diamater orange and black wire which powers the power seats and there is power there, but when I probe the thin orange wire on the lumbar control switch, there's no power."
On the 91, there is a connector (C360) in the r/h side of the console near the shift control lever. If C360 or the "Sport Seat Jumpers" S305 or S306 below the console have come unplugged there will be no 12vdc to the switches at the left orange wire (pin a) or at the right orange/white wire (pin a).
C360 will have the orange/black wire on one side and a orange and orange/white on the other side.
Hope this helps......

Thought Id update this for future reference.
OkieC4 was right on the money... I sussed out that the 2 pin plug (black & orange) that is located on the harness near the gear lever and this connect to another connector on the other side which goes to the driver seat pump. Mine was unplugged and tucked under the carpet...
