where's that 12VDC gone to?

Does anyone know where on an 89 GV, the front porch door switch gets its power supply from? The step stopped working. Since I didn't want to drive with it down, I siamesed the power lead for the floor lamps to the hot lead to the step solenoid. But I can't find the leads to and from the door switch. Heck I can't *get* to the door switch. Guess I'm going to have to remove a bunch of doorframe trim. Simultaneously, the front furnace decided not to have a 12v signal go to it anymore. I'm not sure where I should be running a new wire to from it either. Last but not least I found the ol girl to be down on power and the boost guage is only showing 5-6 psi instead of the usual 12. I can't find and leaks. Trying to find a get-your-boost-pressure-back diagnostic checklist for a 3208T. Anyone got such a thing?

Sounds like the old girl missing out on some monthly exercise...

You're not wrong. 6 and a half buck diesel isn't helping with that issue either...
