Lock / Unlock for doors and trunk not working
I have a 2004 sl500, the door lock stop working recently as well as the trunk. when i use my key to lock, the alarm is ok, except the doors does not get locked, same story if you try to lock by pushing the buttom in the car, all I hear is some noise from the back of the car, and after it stops, nothing happens.
I checked out the forum and was told maybe it's one of the pump stop working, or has a leak,
I took it to a shop and they told me the pump has been ruined by water, I guess because I told them there was maybe a leak in the trunk, and they want to charge me a thousand to replace it.
I'm trying to understand why does the pump still making noise while it's being broken? any idea?
