I just wanted to follow up with you guys, I ordered a used central locking pump off of eBay for $150. Install the used unit and everything worked related to the pump except for my convertible top which is why I started this investigation in the first place. The only relation the pump would have to the top would be the trunk lock, which is activated after unlatching the top, When you activate the top button on the council, the first step is to lock the trunk and for some reason this was not happening, thus no convertible top operation.I then Ordered a new locking pump from a Mercedes dealership that a friend of mine operates. I installed the new pump and the clouds parted and the sun came out, and everything worked as it was supposed to. As you know my old pump was submerged in water and I did find corrosion on the plug connections. I took my time and also cleaned The connectors with electrical cleaner and a tiny wire brush that I use to clean my paint guns. I just want to thank you guys for the help in the tidbits of information you gave me to help me figure this out
