Mercedes CLK 320 2002 Window wont wind up
The battery on my CLK 320 recently went dead after a period of about two weeks of idleness.
I charged the battery and placed it in the vehicle at which point I managed to get the vehicle going again, however....... every time i turn off the engine and get out the car the window winds down about two inches on the drivers side at which point i am unable to get it to stay up again. I can get the window to go up and down no problem but it just returns to the open position again once i have wound it up to the top again, this is VERY INFURIATING!!!
The only time the window will do up and stay up is when i am sat in the car and the engine is running.
If i then turn the engine off and get out of the car the same problem arrises, the window will go down about two inches and not matter what i do will always return to the postion once i try to wind it all the way to the top.
Can someone please help with this issue i would greatly appreciate it???

Method #1:
If windows won’t go up after loss of electrical power. Make certain trunk and all doors are closed. Stand outside by driver’s window. Use key remote to lock car. All windows will go up.
Method #2:
Press power window switch to resistance point until the window is completely closed and hold for additional 2 seconds. Repeat procedure for each window.
Reset Windows Express Feature:
Bring down both windows at the same time by holding the switches just before the click that brings them down automatically. Once both windows are all the way down make both switches click by pressing them all the way down for 10 seconds.. This lets the ECU learn that this is the end of the window track and it records it in memory. Do the same closing the windows by holding both switches and making them click once the windows are all the way up.
Thank you Thank you that worked for me and probably very likely stop my car getting broken into Regards Dave Blundell

Preparation Steps:
1. Make sure your steering wheel is straight.
2. Make sure your windows are all the way up
3. Make sure your sun roof is completely closed (if you have one)
4. Make sure your parking brake is released.
6. Turn off your stereo and make sure you have your stereo's Anti-theft code.
7. Turn off your heat/AC blower
8. Turn off your lights
9. Make sure your doors are UNLOCKED.
Now, disconnect battery 30 secs and then reconnect.
Get in car close the door and turn the key to position 2 (Just before you start the engine but do not start it)
1. Resetting your windows: Bring down both windows at the same time by holding the switches just before the click that brings them down automatically. Once both windows are all the way down make both switches click by pressing them all the way down and hold them for 3 secs (This lets the ECU learn that that is the end of the window track and it records it in memory). Do the same for closing the windows by holding both switches and making them click once the windows are all the way up.
2. Turn on your blower and make both sides go to 72 deg (if you have this typr of heater control) by pressing both up and down buttons at the same time. This will calibrate the ECU
3. Turn on your stereo and enter you stereo code. 4. Pull the sun roof all the way back and all the way forward then up and then done.
6. Turn all you lights on and off, including your fog lights.
7. Turn the key back to position 0.
8. Turn on your engine. You will get 2 malfunctions, your ABS and ESP lights will be on and must be calibrated.
9. Calibrate your ABS and ESP systems by turning the steering wheel all the way to your RIGHT and then all the way to your LEFT, then bring it back to the middle. Notice the two yellow lights disappear from you dashboard.
10. Let your car run in idle for about 5 minutes and then take it for a spin. Remember your ECU is still getting all the readings from all the sensors on your car so drive slowly first then faster... and so on.. you are basically teaching your ECU how to handle your car.
Throttle Reset
1. Get in and shut the door
2. Turn key to position 2 (just before you start the engine).
3. Press the gas pedal to the floor... past the kick down point...
4. Hold the pedal there for 15 seconds
5. After 15 seconds while foot still planted, turn the key off but do not remove it.
6. Release gas pedal and wait 3 mins. Do nothing, you should here a click near key at 3 mins.
7. After the 3 minutes start the car and drive off normally... you should notice a difference in the shift pattern and smoothness.
Service Reset
Turn the car on to the 2nd key position, all the way ON, but do not start it.
- Then scroll through and find the A/B Service notification. Hold the "R" or reset button on the dash. After a few seconds a message will display on screen asking you if you would like to reset the service notification. Once this happens let off of the "R" button.
- Press and hold the "R" button one more time until the reset is complete.
Valve Reset:
(move valve with finger off 90degrees, turn key to 2nd position, let valve close and open, wait for "click", turn off key, turn back on for 45 secs during which time the valve will close and open again, key off (Not been able to make this work)Trunk Release:Remove drivers fuse panel, pull 4 fuses on left 7.5A and 5A, wait few secs and replace then try door unlock switch to see if it works, this will tell you if alarm is deactivated. If not try other fuses.Passenger Mirror auto-dip reset:1- Turn key to position 2
2- Select reverse, adjust mirror down so you can see kerb for reversing etc.
3- Press Green store button on drivers door control next to the seat adjustment for a couple of seconds, then within 3 secs press the mirror control again just once in any direction, mirror is now stored. Return to Gear shift to Park.
4- Wait 17 secs mirror will return to normal position.
5- Select reverse and test to make sure it dips ! DONE.






Although the solution was just a 'door closed' switch not properly actuating, the thread has lots of window operation / troubleshooting details.

The window re-synchronization procedure, only restores erased memory settings, due to either a low voltage condition or an interruption of voltage supply and will not work, when there is a malfunctioning component, within the window system.


@Serndipity Thank You, Sir for guiding to the right place

@A1EK Reset procedure did not help me
