The repairs were going to be over $2000 so we decided to bring it home and look it over before proceeding. There is water in both sides of the trunk, so I pulled the rubber plugs and will be adding some sort of cover to keep road water out but let the tubs drain any future moisture. We will be looking for the leak before any interior panels are installed.

I opened the plastic shell of the central locking pump and it was moist inside but was not holding water. I dried the circuit board and cleaned off some surface corrosion (powdery and light green) and it looks like everything is good. It should work, as it was functioning before it was removed. I will be replacing two pins of an array of 18 that connect to the wiring harness of the car. They corroded away and broke off when the connector was unplugged. The connector itself is a bit corroded, but I hope a cleaning is all it needs.

I opened the alarm module and it was dry inside. I think the only problem here is a broken wire on the wiring harness. The alarm was working before the module was removed.

Once I fix these three bad connections I hope Dad's lights will work properly. And it will be a lot cheaper than all the parts and labor that the dealership was quoting.

I enjoyed reading the RCM no-start sticky that showed how to resolder some bad spots on the RCM circuit board. It helped me to decide to try fixing this one before spending money on replacement parts. Thanks to Tighed 1 for that encouragement.

Updates to come.
