So i installed my 300m seats, the heat works, only if I push the buttons REALLY hard, to the point where it hurts, and I cant use memory at all. it wont let me set it and it wont let me use it!?
Also, the green LED backlight on the heat always stays on, the lights dont need to be on, as long as the ignition is on.
does everybody's do that or do i have faulty switches? please help me... any help will be great.
BTW, i wired it like this:

First look at page 625 of the manual. It shows the main power feed for the seats as coming from the BCM plug #4, so if you flip to page 31 of the pin outs, you will see that circuit D25 is the Violet/ yellow trace for the PCI memory to the BCM, which controls your Radio memory settings.
Next, flip to page 630. This shows the memory seat circuits.
The top is the RED to the junction block/fuse block & Black to ground that powers the motors.
This is the small plug under the seat. On the large plug, you need to find the Dark Blue wire with the white tracer. It goes to the BCM junction block #C4 - the green 12 way plug. Insert the wire into cavity #11. At the driver's seat, you will need to jumper this to the appropriate spot on the passenger seat large plug.
I pointed out the memory wire PCI bus, because while you are "under the carpet" you may as well hook this one in as well, then (perhaps) your radio will operate in the memory mode as well.
The rest of the wires in the harness go to the mirror circuits, so you needn't worry about them unless you plan on putting heated memory mirrors in at some time.
Once you hook up the wires above, the heat and memory in the seats "should" work correctly. This was how I did mine originally.
If you got the Special seats, how come you didn't just take the whole harness? It makes life really easy. It only takes about 4-5 hours to strip out your existing harness and install the correct one.
