Some cars are fitted with autolock,car starts/car locks. some are fitted with driver masterlock button(above door switch panel)so the driver can lock all the doors/unlock for passengers to alight.but to stop you
locking the keys inside/you have them in your hand),car will not let you lock when in on position,keys in ignition/engine running etc.
so you do not have a problem.

All the other windows work ? Not a fuse , one fuse powers all the windows . Test for B+ voltage at the switch an the window regulator would be the proper diagnostic procedure . Do you own a volt meter ? know how to read a wiring diagram ? how to do basic automotive electrical testing . The Faint click you hear is probably a relay , which means the GEM - genaric electronic modual is energizing the window relay . The windows are computer controlled .
The GEM will activate the OTD Relay until one of the following conditions is met:
The LF regulator control switch is pushed to the UP position.
The LF regulator control switch is released (OFF position) and then moved to the down position (first detent) or one touch down (OTD) position (second detent).
Seven seconds have elapsed since the OTD was initiated.
A window regulator electric drive stall condition is detected on the one touch down sense line inputs.
The UP window operation is not controlled by the GEM. The feature is activated when the delayed accessory is active and the LF window regulator control switch is pressed to the UP position. The switch provides delayed accessory power to one side of the motor and ground to the other side through the one touch down relay. The one touch down relay is not active when the LF regulator control switch is in the UP position.
Passenger windows may be raised or lowered using the LF master control switches or the appropriate passenger window switch. Passenger window switches receive power when the delayed accessory relay is active and the LF remote lock-out switch is in the UNLOCK position. When in the LOCK-OUT position, the passenger windows are deactivated.
The GEM controls manual down and auto down window movement with the down window relay. The relay is activated by applying ground directly to one side of the down window relay coil, and deactivated by removing the ground signal.
The delayed accessory relay provides power for the operation of the power windows and the power moon roof. The delayed accessory feature is active when the ignition switch is in the RUN or the ACC position, or when the ignition switch is changed from RUN or ACC to the OFF/LOCK position and the LF and RF doors are closed.
The GEM will deactivate the delayed accessory feature when:
the LF door is ajar and the ignition switch is in the OFF/LOCK or KEY-OUT position.
the RF door is ajar and the ignition switch is in the OFF/LOCK or KEY-OUT position.
10 minutes have elapsed since the ignition switch was changed from ACC or RUN to the OFF/LOCK position.
LF door open warning switch (open circuit with door closed, grounded with door ajar).
RF door open warning switch (open circuit with door closed, grounded with door ajar).
Ignition switch RUN position (battery potential on both the RUN and RUN/ACC inputs).
Ignition switch ACC position (battery potential on the RUN/ACC input).
Ignition switch OFF/LOCK position (absence of battery potential on the RUN, RUN/ACC, and START inputs).

C CLASS (1993-1997), E CLASS (1995-1997), SLK (1996-) Procedure 1. Point the remote control at the receiver - this should be located in the driver's door handle or next to the boot lock button. 2. Press the lock/unlock button. 3. Within 30 seconds manually lock or unlock the vehicle using the passenger's door lock or the boot lock. Alternative method Procedure 1. Point the remote control at the receiver - this should be located in the driver's door handle or next to the boot lock button. 2. Press the lock/unlock button. 3. Within 30 seconds, switch the ignition ON. Alternative method Procedure 1. Point the remote control at the receiver - this should be located in the driver's door handle or next to the boot lock button. 2. Press the lock/unlock button. 3. Within 30 seconds, turn the ignition switch to position II.
1. Place key in ignition lock and turn to position 2 [all ignition lights on] 2: Turn key to off position and remove from ignition. 3. Within 10 seconds: 3a: press the Close
[Lock] button and hold it down 3b: while the Close button is
still depressed simultaneously press the Open [Unlock] button. Press and release
the Open button 5 times [still holding the Close button down] 3c: Release both the Close and the Open buttons at the same
time, and immediately push any of the two Open buttons once [i.e. either the

information is for the resetting of a previously synchronised key to match the
security system after batteries have been removed or replaced. This information
does not work with new keys which it seems must be taken to a person with a key
synchronisation device [or a super-ripoff-expensive MB dealer]
Try locking all doors and with the key unlock the front passenger door and reach across to the drivers door and manualy unlock drivers door dont use the electric locks. Then put the key in ignition and start it. If that dont work then disconcet positive batery terminal for exactly 10 min. hook it back up and start engine.
Method 1: Press lock or unlock button 4 times in succession. Method 2: Switch ignition ON and OFF. Within 10 seconds press lock and unlock button in succession.
This is the only manual reset
If this does not work go to your local auto electrician
The probable fault could be central locking activator passenger door
