hi all,

my td5 had heated manual seats in, and i thought that it was
time to put electric seats in, and after reading a few posts i was short of the switch pack and the seat to switch loom/harness.

while fitting the the electric seat i kept thinking about that there was no wire to power the seat, but put the seats in and all wired up. The heated seats work ok, but cant get the seats to do anything. I think its because i cant see any power going in to them.

all the fuses and relays on both the engine / dash fuse box are full, except for a small relay in the engine box, i did use a spare relay to try but still nothing worked.

Can anyone put some light on this , as there anything that i still need to get ?



thanks

1. there's a white satellite fuse holder with 3 fuses under the front of the passenger seat, did you check those?
2. it must be set on electric seats in BCU with nanocom/hawkeye/etc

all fuses are ok, so must need bcu to be turned on.

Anyone near esher got a unit to turn on the bcu ?

thanks

You may not have the wiring for heated & powered seats, just heated seats, as fitted previously.

The Brown connectors that supply power for heat and powered movement are not all wired the same -

.


On these connectors, terminal-1 supplies power for the heating elements, with terminal-2 providing the path to earth.

Only on vehicles wired for powered seats, do these connectors provide power on terminal-5, with the underseat power relay's (in the satellite fuse box that sierrafery mentioned) earth path (controlled by the BCU) provided via terminal-4 (the seat motor's earth shares the heavy gauge Black wire in terminal-2,with the seat heaters).

The 'CCT' for these connectors shows that -

Pins 1 and 2 = 2

Pins 4 and 5 = 22

This equates to -

2 = Heated Seats

22 = Electric Seats

Have a look under your seats and see if the vehicle loom side of the connectors have wires into Pins 4 and 5.
