Default Door Lock Actuators
My driver's side door lock actuator grew gremlins.
I think.
It click-click-clicks while driving and the "door open"
light on the dash flashes on/off. I know it's not just
the door switch. I've dealt with that before and just
the dash light flashes, no clicking.
Anyway I plan to remove the door panel and look for
any shorts or loose connections.

I even bought a replacement actuator just in case.
I read the FSM re: actuator replacement. It says
you have to drill out some rivets to remove the old
actuator then rivet in the new one. Correct? WHY WOULD
THEY RIVET IN A REPLACEABLE PART? I'm surprised
they didn't locate it under the plenum.

Anybody ever have this problem? Fix?

TIA

Ted

Every door lock actuator on every power window car or truck I have ever worked on the OEM actuator is ALWAYS riveted from the factory. It its nutted and bolted its been replaced before. Sounds like your having a PKE issue Ted.

Good point. But wouldn't both door actuators "click"?
Just the driver's side door clicks.

The intermittent nature of this sounds like a grounding issue. Just my .02.

Do your locks work manually?

No Ted when I Had a problem with my dads 96 his PKE system went haywire and would randomly pop the hatch open. You would get flashing lights and a clicking sound in the car. I was driving on the freeway at speed the first time when it happened which I admit startled me. We ended up replacing the PKE brain and reprogrammed the fobs and it never recurred again. As Mark Twain once said, "History never repeats itself, however it sure does rhyme.

Hi Ted,

'93 and up cars have automatic lockout protection if the PKE system is enabled. If the key is in the ignition and a door is closed an automatic door unlock cycle will occur. The driver's door or both doors will be unlocked depending on how the PKE system has been configured.

Turn the PKE system off and see if the door lock activity stops. If so, there is a problem with a door switch.

I don't know if it matters, but for years I have used an aftermarket FOB
(Viper) anti-theft/auto lock system on my Z. I haven't had a problem
(yet) with it. The factory FOB sits in my desk. Low Battery?
