I recently got the hydraulics rebuilt on my 01 slk and everything seems to be working but my trunk lid will not shut. If I open the top it will go all the way to the point where the trunk should close but the pump keeps running and the trunk lid continues to stay up. If I close the top it does everything but close the trunk. If I push the trunk down and lock it in, it will finish and raise the rear windows. But if I don't close it till it locks it raises the trunk lid instead of closing it. Any ideas?
