How to test windows and locks?

[Eastsids]

So none of the window or lock switches work in my Century except the front passenger window switch. I already have the door panels off, is there any tests I can perform to test the locks and windows? I suspect i need a master switch and window regulators

Starting at the wrong location.

These cars are known to have problems in the drivers door flex boot. Broken wires, and corrosion.

So what wires can i test? I mean i looked in the boot and at the wiring and none looks corroded or broken but ik that isnt for sure.

You cant just look at the wires in the boot on the drivers side, you have to apply light pressure, feel for a disconnect. Sometimes wiggling the wiring loom, while pressing on the window up or down switch (key on) will show you the disconnect.

Honestly i had to go thru the whole drivers boot . My best advice is if you have a garage take the drivers interior panel off and unhook everything power related with battery unhooked . Take the door pins off and remove the actual drivers door off the car and pull wire harness out of the door itself and slid the boot off u will never get the door open enough to repair all the wires or see in that space . So the power locks and windows rely on a main black ground wire to operate the doors and locks and each window has a wire for up and down x 4 in that boot and locks have the same set up 4 wires to unlock 4 wires to open

There is a way to unhook the wires inside the car it self but the e brake and bracket blocks the way and there is 2 harness connectors and u have to follow the wires to the firewall joint power block . No offense I’m 6ft 200 lbs . Removing the drivers seat laying on your back with a flashlight and moving 25-30 year old stuff around . Door pin comes out faster and quicker u can unhook the power wires the drivers side door and pins and slide the drivers door far enough support it on Jack stands with a towel so no scratches can’t be made and give u more room but not take the whole door off completely but u need a extra hand the door is bulky off the body to balance it for a hour or so while u go thru the boot and wires . What I did is find a car in the junk yard your close year and grab the boot if it’s not torn to have a spare . The solder heat shrink new and same thick wire to the broken ones and attach it to the other end and make a new connection .

Ive been busy woth work but yesterday i located the issue. My boot was already split in two so i popped that out, and unclipped the harness from the door panel and pulled the harness a bit to give me some space. After that the problem became obvious. 5 of the wire links inside the boot have came undone. I have 3 white, an orange and black on the door side, and a blue, orange, pink, white and black wire on the dash side.

So i guess i just have to figure out where each wire goes. I was able to pull the harness out the door jamb enough where i can splice in new wires without taking it off the pins. Im a pretty lanky young guy and ive been under that dash prolly a dozen times now i just recline the seat all the way and lay upside down its not too bad

This is what im looking at. Having trouble reading the diagram. I have pink, black, white/blue, white and orange on the frame. And black, orange and 3 white on the door. I think the pink is hot, and orange for the locks and black is the ground?

Is there way to solve it with a test light or meter? Im no electrician and randomly putting wires together sounds like a good way to start fires
