There is a connection between the switch and the "indicator driver" and it could just be a connector problem.(P81) LEFT HEATED SEAT LOW INDICATOR DRIVER CIRCUIT OPEN/SHORTED TO GROUND
Thanks for that, but there are two reasons:Why not just replace the switch entirely? Only $20ish on eBay. Less if you have a wrecking yard nearby.
No, I haven't got round to it yet. And with this cold weather I have decided to wait until the spring. Did see a YouTube video and it looks fairly straight forward.Feichter - did you manage to fix the switch? I now have the same problem with the passenger side. Functions work OK, but switch not visible in dark.
Let us know how you get on, and if you can take some pictures even better!Thanks for the info. I've just sent an email to the Custom300C shop to see if they can shed any light on it (no pun intended). I now understand how the bulb may have failed, as it's filament - not LED.
Whilst typing this reply, I've just received the following reply from the Custom300C shop, so I will go ahead and order the parts:
"yes to recollection they do come out easily by firstly removing the silver fascia first, which will just ease out (easier pulling from the top initially). This exposes the ashtray panel and two switches which can then be pulled out. A long time ago though since I messed with the panels."
