How should I start going about as to why the power locks on my crew cab arnt working?

check for power at the lock actuators when the switch is pushed. if power is present, the actuators are most likely bad.
Do you have Remore Keyless Entry? Here's the wiring diagram for a crew cab without RKE. Start by figuring out where the power gets to and where it doesn't (fuse panel to switces, etc.). Cheers!

Start by putting ALL your truck's details & history (as much as you know) into your signature(<-click that) so it shows with each post, as this page explains:


Phone apps don't always show signatures, so you may need to switch to a real browser in desktop mode on your phone, or just use a desktop/laptop computer. Put your location (nearest city) in your profile &/or signature, & upload an avatar of the truck. The more pics you post (NOT in your sig) of the truck, engine, wiring, labels, & undercarriage, the more likely we can help you. Not all its details are relevant to these issues, but you don't necessarily know which ones are relevant, so just put everything in now. "Stock" tells us nothing because Ford offered dozens of "stock" configurations in these trucks - you need to list every detail. If you're not sure about something, post several pics of it, and we can help. But we only know what you show & tell us about your truck.

What's the history of this symptom? Does the truck have PL in the rear doors?

What’s the process to seeing if there’s power, like how do I go about it

I’m assuming pl means power locks and if it does then yes. I got this truck in September. Power locks didn’t work for the last dude and now that it’s almost Summer I have more time to work on it

Open the door panel and using a volt meter se if power goes to actuator when button is pushed
Does it seem like they are trying to work all? I would start by checking fuses, then the easiest thing to start with is likely pulling the switch panel on the drivers armrest to see if you have power to the switch using a volt meter. If you have power there then I'd start pulling door panels and check for power at the actuator when the switch is pressed.

If I were betting man, I would guess the actuators were tired.
Track down your ground(s) for the circuit first. Trucks are 26+ years old and sometimes the grounds can be needing a cleaning. I’d start with simple things first. So Ground(s), switch in drivers door, then check inside the accordion boot between door and A pillar, drivers door first. Not uncommon for wiring inside the accordion to become brittle and break/short, causing windows and locks not to work.

No it’s a power issue
