steering wheel heater X5 2004
 

Hi everyone

I have a built-in feature for steering wheel heater. However, when pressing the button nothing happens. Not even a small LED on the button lits up.

I've checked fues 29 10A and is OK. Any ideas where to go from here? Guess there must be a relay somewhere. A wiring diagram would be excellent.

I would check if your X came with the option or if previous owner just installed a new steering wheel

I think it does. Also, Inpa does detect button been pressed.
