I'm having trouble with my washer pump on my 2008 cabriolet. It wasn't working so I pulled the actual pump out of the plastic reservoir. If I was to just buy a replacement (which looks like the original) can I just re insert it with hose and electric? I figured I would take out the plastic reservoir since someone said you only need to remove the one nut in back of the wiper motor. I did this and there doesn't seem to be a way of removing this without major disassembly. On a side note I had to remove the wiper motor plug and it caused much grief. it has a locking clasp which looked like it was easy to figure out but it took an hour and I ended up ruining the clasp that keeps it firmly in place. I'm still able to plug the 2 back together but it's not as tightly fit as before. Anybody know the right way to disasemble a plug?
