97 LC: Door Lock Issues after removing Prestige Audiovox APS-400 Alarm System

[Charles4x4]

Hi all, I gave up on fixing it and removed my Prestige Platinun by Audivox alarm system, model APS-400. Before removing it, all door locks worked fine.

After removing it, only the drivers door lock works. I know this system was a Southeast Dealer Install only one, but the install on mine looked more “inexperienced” than the others I’ve seen pics of. The aftermath of wiring is attached in pics.

Does anyone know what I should do to get this all back to the Factory Wiring Setup? Even pics of your wiring in the Drivers Kick Panel would help! Thanks.

While I don't have any experience with that particular system, I've played with several others over the years.

*Most* of them tee into factory wiring or interrupt a factory circuit. You can likely trace the harness from the main box of the audiovox and find where it has plugs that tee into a factory harness or a factory wire is cut and spliced into and out of the audiovox harness. It should be a relatively easy job to remove it.

If you're not comfortable pulling it out, a local audio/alarm shop would likely do it pretty affordably, or as part of upgrading to a modern keyless/remote start setup.

All the pics above are from After I pulled the system (which was pretty easy).

ahhh- sorry I misread that it had already been removed.

A cursory look shows that blue wire with the white tracer that is cut is the power (+) to all other door lock actuators when it comes out of the drivers door lock actuator and door lock control relay. I'd guess that there is another end of that you need to find and reconnect in the harness there on that same bundle of wire.

The two smaller connectors you show, with one wire each- were those plugged into part of the audiovox harness you removed? I wonder if you need to de-pin those and put them back into the factory harness. It almost looks like the brown wire needs to be pulled out and replaced with the red wire/blue tracer. I can't tell for sure from your photo... the blue wire w/red tracer might have a home in the same connector as the cut blue/white wire. Does that connector have a cavity and a corresponding wire on the other side?

I'm not suggesting you go randomly hooking up stuff just yet...but it looks like that may be the case. The door locks are a simple polarity reversing circuit and it's possible the wires were pulled to go into the audiovox module. I can't see a brown wire anywhere in the door lock control circuit, which makes me suspicious that it may be aftermarket.
