Most electrical components on BMW X3 models require programming using an advanced BMW scan tool when replacing. With that said, don't feel you can't replace these items yourself. You also have the option of swapping out used items, which will at times work with programming. I don't have experience with this method, due to my access to a BMW scan tool, but it is something to consider. I have been by been told programming of used items isn't always required, so this may be an option, but be prepared for this not to be the case. As I cannot vouch for it.

The seat heat control buttons are in a combined control panel with DSC (dynamic stability control) button. The failure mode of these buttons is quite simple. You will press the button to activate your seat heat, and the LEDs will not illuminate as they have the past. This may also be due to a break in the circuit further down the line, like in the seat heater itself. So be prepared to check fault codes before pulling the trigger on replacing the control panel. Most of the time, I find the control panel at fault.

Remember your car may have been serviced before and parts replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.
