I need help

I asked this in the W203 area and have received no responses. Hopefully someone in the general area can help.

I hope someone can shed some light to what may be going on. The entry/exit mode is not working in my C320. To go a bit deeper, the lever on the steering column will not adjust the steering wheel position nor will the seat adjusters move the seat with the key in any position. I have checked all three fuses and they are all intact. Could it be an issue with the "smart key"? Thankfully I was the last person to drive it and the seat was adjusted to my settings. It is just annoying that it is only the driver's seat that has the problem. The passenger seat still is functioning correctly. Thank you for help.

I don't see how it could be the smart key even if you had key dependent settings active. In any case, have you tried the other key?

If fuses are OK, perhaps you could check from the control box that it receives power (and ground), otherwise an issue with the control box would be my guess. Could try resetting the box, might recover operation temporarily.

heres a quick easy check for the control modual
make sure you have the radio code handy
removed neg term on the batt for 5 min
reinstall and check function.
what this does is reset the control moduals
if for some reson the seat or door mod locked up this will unlock it.
this is normal i see it all the time. if it doesnt work. i suspect the seat mod.
