Re: driver power seat adjustment and steering tilt not
I had the same problem, the c and s class seem to have the issue with the power seat and steering wheel adjustments. On my 04 it was two bare wires under the drivers seat that were touching and blowing the fuse (fyi)

A control module ! Electronics
The steering column has a tilt/telescoping control system that consists of an electronic control module capable of class 2 serial data communication, a steering column power assembly with positioning motor and sensor, and a steering column control switch. The multi-function lever provides for the control of the headlamp high beams, and the windshield washer and wiper.
The tilt/telescoping steering column in/out/up/down switch is an input to the driver position module (DPM). The tilt/telescoping drive motor is an output function of the DPM.
Steering column memory settings are stored in the DPM. The steering column position sensor is an internal part of the tilt/telescoping motor assemblies, and is an input to the DPM. The DPM uses the position sensor input when storing and recalling memory settings.
Same thing with the seats , electronic control module .
Battery positive voltage is supplied at all times to the memory seat module (MSM) through the battery positive voltage circuit from the POWER SEATS circuit breaker located instrument panel (I/P) fuse block. This voltage is used to power up MSM and also to apply power to the seat motors when commanded. Battery positive voltage from the TILT/TELE SW/MEM SEAT MOD fuse located in the body control module (BCM) fuse block that supplies voltage to the seat adjuster switch and the memory function switch, also supplies voltage to the MSM. The MSM monitors this voltage circuit in order to determine if battery voltage is supplied to the seat adjuster switch. The MSM is grounded through the module ground circuit and G301.

At the bottom of the tilt steering coloum is four bolts that, sometimes, come loose and, from time to time, will come out. If this is the problem have a flat bed tow truck take it to the mechanic. Again, if this in the problem, "YOU DO NOT WANT TO DRIVE IT"! Trust me. VSA
If your driver's seat and the steering column adjustments are not working, check the switch assembly on the side of the driver's seat. Look at the wiring harness plug. Is it properly and securly plugged in? This is a common problem, the harness plug housing breaks and the plug comes loose.
Most often, the stuck steering wheel is a result of a faulty 'tilt relay switch.' If you attempt to use the tilt switch and you can hear a clicking/whirring noise, then its your relay switch, if not, it may be the motor that is broken.
I have the same problem. Seat and steering column just stopped working. Passenger side normal. No fuse for these components. With so many postings witht he same problem there has to be a defective or worn out source. Please post if you find a solution!
you will not alter the steering angle more that what you have
however you can raise the seat
get a piece of RHS x 1/8" thick ( comes is dimension 1x1", 2x2", 2x1" and 3x1") and by drilling new bolt holes for where the seat runners are , you can raise your seat up to 3"
Any body with mechanical experience can do it for you or get an engineering shop to make the bits for you
