yep...moisture (yes moisture) messes up the PSE pump and the 71 fuse can blow. I think it's part of soft-close, so would like to hear how this works out. probably simple. The added question to the community is there a hack for this issue? A friends SL500 has a humid trunk and gone through this issue a couple of times...does anyone make a solution for water dropping down in the well with the hydro pump and PSE? It reminds me of the immobilizer sitting under the drivers seat of my porsches, if it gets wet, car is dead and you are looking at a significant expensive repair, but solved by an aftermarket tray.
