Question about 2007 Mercedes-Benz ML320 CDI

2 Answers

The door locks on my vehicle are acting up. Every time I come to a complete stop and start up again the door locks click on and off.

The year is 2000. Now one of the doors double clicks several times and it will not lock anymore. One of the other doors you have to manually unlock and then push it down to get it to lock. How do I fix this?

This could be a break in the wiring loom normally on the drivers door as this door is opened and closed most frequently its normally in the section between the door post and door inside a rubber sheath check all the wires for condition and continuity.

This is usually a fault with the master lock , the one that sends signal to the others , usually this is the drivers door lock , to check the master lock will have 5 wires and the "slave" locks only 3 wires , so replacing the master lock , as repairing is not economical or impossible just do a few electrical checks before changing ie check for power to and from lock , earth and wire condition etc

What is causing clinking sounds when unlocking the doors with the remote? I also hear clicks when shutting the car off when the locks auto.

Next time notice the manual lock. If it is moving with the click noise, the lock actuator is going out.

I have a 2003 PT LImited. The door locks intermittantly lock-unlock lock-ulock, lock-unlock several times regardless of speed, it happens while idling, driving forward, and backing up. About a year ago...

The RKEM (remote keyless entry module) is the problem.
Only a DRB-III scanner can program the transmitter codes and VIN number to remedy this problem....I hope this helps.

When I use my remote starter & door lock/unlock and the lock/unlock button in the car, it does not lock or unlock both back doors. It does start the car, opens the trunk, and lock & unlock both...

The rear doors probably dont come w accuators in them. Meaning that the rear doors alot of times don't have power options. If you are certain that your rear doors have factory power locks then I would say it's a wire somewhere...did you try a double click of the unlock button. My two door chevy truck unlocks the driver door with one click and the pass door requires a double click. Hope this helps !

Emergency fuel door release for 2000 Volvo S80

Copied from Volvo Forums

I had a similar problem w recently bought 2003 S80.Several points: 1) Access your locking selonoid through the trunk interior panel ... loosen a few hex bolts and slide out for maintenance; 2) I fixed my lock by simply using light teflon-based oil (like for bike chains). I exercised it a few times and it works beautifully; 3) Not sure on your model, but gas door on the '03 unlocks when you push the associated release button under the headlight control switch. It is not designed to unlock w the key (again, check owners manual for your year). Hope this helps. master_pre08-04-2007, 09:35 AMYeah, the fuel door on my 2000 S80 is connected with the door locks. In order for it to open you have to unlock all the doors to the car. Sssnake08-14-2007, 03:39 PM Thanks Guys,

I removed the locking mechanism and applied a little silicon graphite and now it works like a charm.

The remote unlock for my 2000 Jetta no longer works on the driver door. It unlocks the other doors and pops the trunk. Is it the lock? I have to use the key to unlock the drivers door.

First thing to do is check for a burned out fuse. If that is not the problem, then check for a defective relay. A lot of newer cars, including VW's, use relays for several things, including the power door locks. If you have the owners manual, the location of the fuse and relay box should be in there. If not, try to find a repair manual, or an on-line repair manual such as All-data or Mitchell on-line. If the problem is not the relay, then the problem is either going to be in the control module that recieves the signal from your remote and sends the command to lock or unlock your doors, an open in the wiring, or both lock solenoids went bad on you. As a reminder, always use caution when working on electrical systems, ans accidently shorting out something could cause a lot of other problems.

On 2000 explorer changed steering colum&key now it only turns.

What will only turn over? The engine? I suspect you have anittheft and your new key needs to be programmed for your truck. You can do it yourself if you have the 2 original keys that came with your truck. the instructions are in your owner manual.

It usually invoves locking & unlocking the doors, turning the key on & off several times, locking the doors, etc.
