Seat upgrade problem from 2003 STR to 2005 V6
Hi All
We are trying to fit some nice 16 way adjustable STR seats from a 2003 car into a 2005 V6 that only has 10 adjustable.
The passenger seat works fine, but the driver's seat not.
Heating elements seem to work (or at least light up) but the driver's seat has no motor control at all.
We got a secondhand 2005 16 way seat module and fitted that, no change, it is not working.
Putting the original seat back in shows all is ok with the fuses etc.
I understand that there may be a change to the wiring loom between 2003 and 2005? Not able to find anything on it.
Is there a change to the protocols? CAN and SCP to just CAN?
Why does the passenger seat work?
Any advice welcome.
Thanks
