Take it to the dealer.
Check ur cps sensor
Check the window switch.
It has no specific fuse. Check the switch, first, since it's the first thing to go. You can remove the switch panel and swap wiring harnesses with the back window. If that switch moves the window up and down, order a new switch from performanceproducts.com. If it still doesn't work, open the door panel and check to see if you're getting electricity to the door window motor. If you are, then you'll have to replace the motor.
There is no dip stick in the ML for the transmission box - It has to be done by the Mercedes Dealer who has the required dip stick Hope this helps
Check power to window switch. Common cause. Check power to window motor. If none then check fuses/relays.
Try swapping it with the driver's side switch
i would first check to see if power window master switch is good usually if more than one window doesnt work, that's where the problem isfords also have a lock on the master switch for windows other than driver window. check that is not engaged
Short in the window switch . Check for bare wires before ther is a fire...
The can with a drip is the oil indicator. If the light comes on, check the oil level (well, you should check the oil at least once a week).
if manual, window regulator. if electric, check fuses, window switch, window motor, window regulator.
check to see if the window switch of the driver's side is getting power, if you are getting power to the switch and the switch is sending power out to the motor but the motor is not responding the motor needs to be replaced
First, check to see if you hear anything when you try the window switch, if nothing and the other window works probably the window switch. Could also be the motor but try the switch first, it's a lot cheaper.
You should check local used dealers. Otherwise shipping with take any you would save. Look for used ones in the classifieds as well.
check power to the window motor by removing the door panel, apply power to two teminals and then reverse terminals window should go up and down when direct power is applied if so your motor is good, if not either a bad relay or a bad switch ANSWER FROM ME THAT IS DEFINITELY NOT the first step. ML320 window switch problems are usually not the motor - they are the switch -- at the console -- lots of info available at MB forums. There is copper in the switch and it bends/wears with time -- usually the drivers side. There are 2 options: Take out the switch module and repair it [per MB forum member instructions] Replace the module [it is in a bank of 4 - so you're replacing all the 'switches']. You probably had stuttering of the window before it failed? Here in MA -- mine failed this winter - -So I plugged in the hair dryer outside and just heated it up to get it "UP" -- and tried to remember not to use it.. But just like high school physics -- heat expands and voila! The switch component is not tooo expensive....
Remove door panel to check wiring to switch and motor See if motor is getting power through the switch - if so motor is bad If no power to motor check operation of switch - jump wires to test if window works bad switch
electric window motor bad or switch is bad check the motor and see if its getting power if so motor is burnt up if not switch is bad
Remove the window switch panel, Spray switch contacts with WD40. Test operation. Not working? Check voltage on switch contacts. 12 volts on input and at least 11 volt on output to window motor when activated is required.
check the following; fuses, relays, regulator, window motor, off track, window switch. did not specify if it was manual or electric.
un plug the connector at the window regulator, check for 12V, if you have it when you press the switch up or down, its your regulator, if not it mat be the window switch or a problem further up a wiring diagram Justin
If the vehicel is several years old, this could be due to a fatigues cable in the gaiter which connects the door to the door column. The solution to this questions is answered elsewhere in this web site. it could laso be due to a failed window switch. To check this, remove the window switch be 'leavering'it out of its recess and use a voltmeter to check that when the button is pressed, a votage appears on the appropriate terminal to operate the window. You can check this out by first operating a window which works.
A faulty power window switch or faulty wiring. The motor works in either direction (there is only one motor per window), so it's not the motor but the wiring or the window switch. Unless the motor control is damaged, that is. Check the switch for continuity first, then check the continuity of the wiring. If you don't find the fault in either of those places, check the motor assembly. Post back here with your findings. Thank you.
check for broken wires in the door and check for pawer across the switch drive safe
NOTE: Anytime the battery terminal has been disconnected, please initialize the driver's door power window and front passenger's door power window after reconnecting the battery terminal. With ignition switch in the "ON" position, do the following: 1. Push down and hold the driver's door power window switch to completely open the window. 2. Pull and hold up the driver's door power window switch until the window closes. Continue holding the switch for approximately one second until the switch changes from blinking to a constant illumination. 3. Check for proper operation of the "one-touch open and close" function by fully pushing the switch briefly to the "DOWN" and "UP" positions. At this time the power window switch for the passenger's door window should be blinking. 4. Push down and hold the passenger's door power window switch to completely open the window. 5. Pull and hold up the passenger's door power window switch until the window closes. Continue holding the switch for approximately one second until the switch changes from blinking to a constant illumination. 6. Check for proper operation of the "one-touch open and close" function by fully pushing the switch briefly to the "DOWN" and "UP" positions
check power going to the switch , and power coming out of the switch ,if no power check fuses and wiring for open or shorts , then remove door panel and bench test the motor basically put power to the window motor
switch on driver side door rear windowsAnd if the switch doesn't work - check out the "Related Questions" below for more details on the rear window motors.Check the fuse(s) too...
