Power Door Lock Actuators
« on: April 21, 2009, 07:08:38 pm »
Folks
This one has me scratching my head.

I have figured the wiring from the door lock actuators, lock/unlock switches ,to the polarity reversing relay. Everything works as it should...when it's hot-wired.

However, my relay has no power and without a schematic (power locks are not shown on the schemas in the forum) its difficult to trace the source. It's a heavyish orange/black cable...

Anyone know where it is fed from?

The power windows/locks have a separate harness the gets power from the fuse box, it is also grounded on the side of the cowl.

My fuse box doesn't seem to have a window/lock marking for a fuse...do you happen to have a fuse layout diagram, Captain? Your help is appreciated.

I don't think it's fused at the panel, just getting it's power from the panel. This power then goes to the separate harness.

It should plug into fuse block cavity E but you didn't provide any info on your truck.

Thanks for the helps guys - three locks working, one bad actuator (driver side, rear), and I re-sited the polarity-reversal relay as it was in a total pig of a location.

Strangely enough, the window and lock circuits are on separate fuses. Looking at the fuse block, right side topmost fuse (which was unmarked and missing) was for the power locks.

Live and learn...

Is this a pickup, 4 door or suburban?
