Hatch key releases, but switch just cycles hatch motor
OK, 92 Camaro Z28 5.7L Hardtop
I have looked in hatch threads a lot and could not find a diagram or a solution.
(If I missed it then shame on me)
The key behind the license plate releases the hatch like it is suppose to.
The mechanical rotation triggers the proper release.
When I close the hatch, it grabs and the motor brings it to a tight locked position.
OK, now when I use the hatch release button inside the car, the hatch motor just cycles to release and locks back down.
(The solenoid is not doing its job?)
I need to learn how it is not triggering the mechanical release the same way that the key switch is.
I need an exploded view diagram of the hatch release assembly,
Or a really good explanation on how the interior switch is suppose to start the solenoid to release it the same way the key rotation does.
I have looked high and low; (I guess not well enough?), and cannot find the right diagram or the reason why this is doing this.
You all have heard of male pattern baldness? My Wife says I have male pattern blindness...

I am sure I have seen a schematic on here at one time. The positioning of the switches is pretty important. Give Lon a call at Top Down Solutions, they have all the parts you need, Lon is very knowledgeable. https://www.top-downsolutions.com/hatch-pull-down-items
Disassembly is fairly straight forward if you take your time at it.

Re: Hatch key releases, but switch just cycles hatch motor
Sounds like everything is working, so the problem(s) are likely to be: 1) the struts are too weak to lift the hatch out of the latch without human assistance after it's released, before the mechanism's reversing switch activates and pulls it back down; 2) the hatch has become slightly out of alignment, which is common as 3rdgens age, and it isn't free enough from of the latch to let the struts lift it without human assistance, before the switch reverses and pulls it back down; or 3) both, 1 and 2.
If the worm gear inside the motor has worn out, which is also a common problem due to age and usage, then the motor will run continuously without results either way, not much up or down movement, not strong enough to lock the hatch back down and will just keep on spinning. But you didn't report a continuously running condition, so I'm going with number 1, 2 or 3, above.

Wow, thank you all for your help.
@Bow_Tied really helped me with the handwritten notes about initiate and sustained.
Evidently, the key switch will bring the "latch" limit switch all the way to unlatched.
So, what I need to do is find a way to get the solenoid to do the same thing.
It is probably not extending far enough to get the latch switch all the way to unlatched.
I will try this as soon as it stops raining here.
I will let you all know the details of the solenoid adjustment, (If it can be adjusted?), if it works or not.

OK, here is the problem that I have discovered. The little cam arm that pivots on the underside slope of the fixed block does not move enough.
The latch will unlatch with the key, but the little swing arm does not rotate enough to unlatch it.
If I manually close the latch and function the unit, the little arm rotates just not enough. I know this because if I just push it slightly, the latch un-latches.
OK, the video does not show the latch arm functioning like this, but it does show the arm movement to the end of the fixed block.
OK, here is what I'm thinking, the unit is not raising up high enough? there is too much play where the base of the arm attaches to the latch mechanism?
What do I do now?

Re: Hatch key releases, but switch just cycles hatch motor
Need to make an adjustment so the arm moves a little more.
How can I do this?
Look in the video at where the arm stops on the underside of the slope.
If it would just move an 1/8" more, the latch would unlatch.
How do I accomplish this?
