After checking my fuses,I told it was a bad door lock accuator on my 01 ml320. It was actually my passenger rear door (right rear). The cost to repair is roughly 500.00 or more,given that the acuator itself is over a 100.00..Check your fuses first..Hope this helps....
You need to remove the door panel, the outside handle and lock unscrew the 3 bolts near the latch unplug elect plug and remove..The rear locks u need to remove the window rail on the left side to get lock out its 2 tight with rail installed
doors locks & trunk lock not working
In my case I have a 1999 SL1 and the clicking sounds where the relays for the electric door locks. I removed them and I have not have the battery drained. I have not replaced them yet.
there isn't one. it locks with the door locks. unlocks when doors are unlocked. doesn't pop open you do it by pushing in the door on the front side.
There is no latch. The fuel door locks/unlocks with the doors.
There is a fuse blown I think is f31
it might be a safety thing
On my 1992 190E I can lock the trunk with any of the keyed locks. If you lock the doors, the trunk locks and if you lock the trunk, the doors lock. In other words all the keyed locks are electrically interconnected. In reality the locks are not electrically interconnected. There is a pump in the right side wheel well of the trunk, it uses vacuum to lock all the locks and pressure to unlock them. Although the pump is powered electrically, the locks are not.
I removed the 75 amp fuse in the trunk box of my 93 400sel, left it out for 5 mins and put it back, all vac locks work again
It is interesting that you make that observation. I am not sure all owners would agree with you.
from what im told the locks on the car are vacuum lines, perhaps your vacuum isn't working or the lines have popped off.
The gas cover is sometimes locked when the trunk locks. Therefore, unlock the trunk and the gas cover will be unlocked..
