So I've read a lot about the wiring pathways and issues with power door locks and windows on ye olde fox bodies. But I'm not sure what could be causing my issues at this point (outlined below).

Power locks no work on either side:
Fuse good
Passenger door won't lock with key, suspect bad lock actuator.
Power to switch, no power coming out of driver's switch
Replaced switch, power out of driver's switch, but no work on either side. Ordered new actuators off Amazon and will do the rig setup people shared in another thread

Power windows:
Both doors worked intermittently when I first got it a few months ago.
Then passenger window would only go up with driver's switch, but went down fine with either switch
Driver's door worked fine
Then neither window would work from either switch
Power to switch, not out.
Put new switches in,...
Fuse good
Power to switch and out of switch when pushed, dome light even dims when I push either switch (driver or passenger), so power to the motors is being supplied..
Driver's window still won't work, passenger window only works from driver's side switch now

I had the dash apart when I did the interior, so I suspect I may have jossled the plastic ignition switch (replacement on the way), but if that was the case, I'm assuming I wouldn't be getting power to the switches at all.

Tried jiggling the key and cycling ignition cylinder while holding the switches. No movemento. But I'll replace the switch and wiring anyway.

Next is pulling the door cards.

Any ideas from the experts?

Buy a cheap China knock off power probe, something like a p100 top diag for around $30 is fine, this will let you supply power and test the motors/ actuators before wasting money on other things. All these parts are old as dirt now so many are locked up, have broken bushings like in the windows motors are super common and can be fixed with some small 1/4-20 hex nuts for a quick hack to replace the plastic bushings or just plain busted, most of the switches will come back to life with a good cleaning of the contacts, almost all where dead simple copper contact switches.

The door power switches has its own jumper harness that runs along the kick panel and under the dash, your going to want to probe those connections to see where power stops, believe its a green 8 prong rectangle if I remember right on most year, harness wires are typically pink.
