New owner of 1999 S500 with trunk problem

This car was bought about a month ago and I am quite impressed with the ride although the trunk is causing me alot of grief! The trunk lid release switch light remains on and it is impossible to close the trunk at all. I have tried the Manual closing option and that is not functioning either. The eye of the latch does not seem to go in and there does not seem to be a position 3 (as in the manual). I can only get the light on the switch to go off is when I close the latch hook manually. The trunk is being held shut with bungie cords... not too classy Is there a way to reset the trunk lid release switch without fiddeling with the battery? Any help would be appreciated for this newbie. Thanks

I can help you a little bit. I have a 1999 S500 Grand Edition and I have had issues with my trunk. From my research it seems that there are 2 pump systems. One for the Doors and Trunk Handle and One for actually pulling the trunk down.

My trunk closes and the handle pulls in but the trunk does not close all the way. When I go over bumps or pull up lightly the trunk will release a few inches and the handle comes out. When the handle is out that means the red light will be on in your dashboard.

There are so many possible combinations going wrong and most likely your pump is failed totally if you cannot get it to close at all. Try pulling Fuse 9 and Fuse 3 to reset the pump. If this does not reboot your pump it is probably dead

If its not dead then there is either a leak in the lines of the pump or the pump pressure is too low or too high, which can be adjusted (I believe instructions are on this forum somewhere).

Hope this helps..If anyone can help my get my trunk from partially popping please help me!!!!!
