Whinning noise heard from inside car on idle and acceleration


Might be a bearing in one of the accessories, such as the alternator or power steering pump. Try to isolate to a specific location, especially as it gets worse.

How do i open Mercedes-Benz 1998 E320 trunk from the fuse box under the hood


You may be able to unlock the trunk from the door lock pump under the back seat. Remove the rear seat bottom and the insulation from the right side. You'll see the battery and a foam box. The door lock pump (PSE) is in the foam box. You need to remove the vacuum line for the trunk latch (labeled RTR or RHR on the PSE pump) and apply some air pressure to it to unlock the trunk. You should then be able to open the trunk normally, unless the trunk lock key tumbler is in the lock position, then you need a key to get in.

Cant figure out how to open rear trunk, the remote seems to be unlocking it. it wont open. is there a safety feature or is it broken ????


if you can hear it clicking inside, it more than likely came out. the linkage should be held in place with a plastci clip, if that broke you could be stuck taking it to mercedes. did you try the key. if it works with the key, then its the actuator itself.

When I press the power door lock switch on my 2001 mercedes SLK 320 to lock the doors, nothing happens however i hear a whining type noise in the truck


Looks like the trunk lock has a problem and not locking with the rest , as the rear lock ia a master lock. You need to check it and replace if necessary.
