If you get no "click" the problem is likely in the switch; if it clicks but won't move enough lube the lock mechanism.
On my '88 power goes from the PWR ACCY circuit breaker through the switches to the door motors and to the theft deterent system.

Re: door lock actuators (65Z01)
Thanks for the reply,but i have the actuator disconneted from the lock it will unlock but not lock and these are new actuators.I also have an 88 vert that i swapped actuators same thing.Someone correct me if i am wrong i heard somewere that there is a relay behind the information panel for the locking system.Also does the stock alarm system have anything to do with the door locks becouse i removed the door handle to repaint the car and then reinstalled them.Any wiring schematic would be helpfull.

Re: door lock actuators (mak567)
I do not believe there is a relay on the 89 door lock system. You should be able to check the operation of the solenoid of the door by disconnecting the link at the top of the soleniod and activating the lock switch. I would look at the door lock switch. I have a Helms manual (with wiring diagrams) and let me know if you need info from this!

Re: door lock actuators (Sam Lam)
MAK: I tried to send the wiring diagram to you this morning on two occasions and both were returned due to problems on your end. I will try again tonight and see what happens!

That diagram is for an '86; notice there is no door lock relay for '86+.
The theft deterrent stuff shouldn't be causing this because it is in parallel w/ the actuators, although one of the wires leading to the theft deterrent could be shorted.
One of the switches could be faulty, or (referring to diagram) circuit 194 or 294 could be shorted to ground. Either would cause the problem you describe.

I have had both door swithes on my 86 act like this. I replaced the passenger side several months ago and now the drivers side is locking but not unlocking. However, the passenger side still locks and unlocks both sides. I should have replaced both at the same time. :cheers:

Re: door lock actuators (dwestsr)
Thanks for everyones input on this matter.Sam Lam thanks for trying to send diagrams i am getting all my other mail.I went on to the link that Jasonl sent me and got the diagrams.I think i have narrowed it to a ground maybe.Took both actuators and hooked them up direct to +&- they both work lock unlock.I have power going from the switch to the actuators both ways but still nothing.can anyone tell me were the ground circuit is,when i apply power to the actuator from switch and then ground the other wire actuator locks-unlocks depending which wire has +or-.Any further help is appreciated. :confused: :confused: :confused:

Re: door lock actuators (mak567)
OK, sounds like the actuators are working. It could be a ground wire issue, but you haven't eliminated the possibility of faulty switches quite yet.
Disconnect the battery!!!
Refer to the schematic again and check for continuity (zero resistance) between the proper terminals while at rest. If that checks out, then check the proper terminals while holding the switch to the lock position, then again for the unlock position.
To clarify, you cannot lock from *either* door switch, or just one of them?

Re: door lock actuators (JasonL)
I tried 3 different switchs.When i press switch one way i get power at the tan wire if i press switch the other way i get power at the grey wire ,if i have power at grey wire and then run a ground wire to the tan wire i get the actuator to unlock and vice-versa,so that is why i think that it is a ground .Do you know where this circuit is grounded,what grounds this circuit or anything that i might try. :(

Re: door lock actuators (mak567)
OK. You are probably correct, it does sound like the wiring. Maybe Sam Lam can post the circuit path from the switch to ground since this is probably year specific and I have a '96. Sorry I couldn't be more help.

Re: door lock actuators (JasonL)
I must confess I am better at cars than computers. JasonL, do you mind if I send you the wiring scan and you post it? You can reach me at ar1943@charter.net. Regards, SAM

Here is what Sam sent:

http://shell2.lomag.net/~jhliao/other/89doorlock2.jpg
First page is schematic, it appears to be nearly identical to the '86 scan posted earlier. Second page is a diagnostic chart. I think you have done most of this but I would look through it anyways.

Re: door lock actuators (mak567)
If you know both door switches are good, it appears you have a ground
problem.
On the Passenger Side Switch you should see 3 black wires going to the
switch. (Two of them are on Circuit 150 on the Schematic). On circuit 150 one black wire goes to pin B on the switch. This black wire completes the circuit when you Unlock the doors.
The other black wire on Circuit 150 goes to pin E and provides the ground for the circuit when you Lock the doors.
With an ohm meter you should measure zero ohms to ground on both of
the black wires. In your case, it looks like the black wire on pin E is open or
the socket/pin for the wire is bad.
For test purposes ground pin E on the switch and you sould be able to Lock
the doors.

Re: door lock actuators (Hooked on Vettes)
Indeed power is provided to both switches via the Orn/Blk wire but ground is only supplied to the RH door lock switch via the two Blk wires.
The Blk and the Lt Blu wires go between the switches to provide a ground path for the LH door lock switch.
So when you hit Lock or UnLock both the Blk wire and the Lt Blu wire should be at (or very close to) ground potential. And the two Blk wires on the RH switch should always be at ground potential.
BTW, are you sure that the new switches are indeed DPDT types?

Finally fixed problem.Some idiot removed the aftermarket alarm and did not reconnect lt blu wire circuit 195 and 194 blk coming out of the driver door.Thanks for everyones help on this matter. :) :) :)
