-The chassis ground is worth investigating. As I said the car was sitting for 8 years to date, so it's very likely. Best guess 7ish years when I noticed the problem with the spoiler and most likely the wet CLP. The first repair was replacing the CLP and connectors back in December, only 2 connectors needed to be replaced, and I was VERY careful when splicing the new wires and plug assembly to the new pump. The pump worked and the doors locked/unlocked as expected.
My caution is that you should be VERY CAREFUL about "Cleaning" those connectors - because you cant. You see, the contact between male/female pins is not all that impossible to clean, but the issue is the crimp that you can't clean, that is the crimp between pin and wire. This is where so many problems are caused.
I'ts the contact from aluminum pin to copper/copper clad wire, the arrow points to the problem area:
I first ran into this in the 1980s when working on Motorola Micor/Mitrek radios in emergency vehicles. Some facilities would wash the inside of the vehicle with a hose, they'd cover the radio heads, but then get the cables wet and water would "wick" down the cables and into the connectors. (My first 29 years in the industry was as a field technician doing component-level repairs.)
