Okay, Ed Borland, Eds-Red-05, came over and we dove into the Switch problem.
Ed is excellent with electric schematics and traced the problem to the Shift Lock Control Actuator located in console which will not energize.
We bypassed the actuator and key solenoid worked fine. We tested the actuator outside the truck and it worked, sometimes.
Can't order JUST the actuator, have to order WHOLE shifter which includes the actuator. I searched the internet and can not come up with a part # for the actuator (see picture).
Best part, Shifter assemble is on BACKORDER from GM. Seems they are having a problem with Blazer, Envoy, Tahoe, SSR and a redesigning the Shift Module.
Maybe Greg Ducato knows where to get them.
Anyway the saga continues.

1. Minor removal to get to switch, seat, Windjammer, Waterfall, Console, Console frame. Bingo!! There it is!
2. Shift Lock Control Actuator and connection.
3. Bypassing Switch to prove solenoid bad. I also order transmission solenoid which send the signal to the Console Lock Switch. Might as well do it all.
4. This is Shift Lock Control Actuator
5. Switch apart and you can see solenoid pushed plastic assemble to press micro-switch.
This bulletin is being revised to update the model years and add the SSR. Please discard Corporate Bulletin Number 05-07-129-001A (Section 07 -- Transmission/Transaxle).
The automatic transmission shift lock control actuator is now available for service as a separate part. The actuator was formerly available only as part of the entire shifter assembly. DO NOT replace the shifter assembly if the shift lock control actuator requires replacement . Please refer to the Automatic Transmission Shift Lock Control Actuator Replacement procedure in the Automatic Transmission sub-section of the Service Information.

No matter how much you push the envelope, it'll still be stationery.
Thanks YELLOWBEAR, I am going to check it out. The older MODEL part had only two pins instead of five. Trailblazer has a NEW Actuator that mounts the same and looks almost the same but only TWO pins.
Marc Called and I have the shifter coming. It is now OFF backorder.
I couldn't find the part without the shifter.
I will post pictures of the install when it comes in next week.
Yes, I could by-pass the Shift Lock Control Actuator but if you forget to put it in PARK and walk away, it could roll away.
In fact I am by-passing the Actuator, I drive it everyday, one seat short and lots of loose parts hanging out.
Thanks for posting the fix Dick, we have yet to have to repair one of these in the shop, guess we have been lucky so far but as the fleet ages we will no doubt be presented the opportunity.
I searched all kinds of Parts Site, ACD, Amazon, etc. Not available, and the part # that came up did not match and there wasn't any description or picture that tells or shows FIVE pins.
Dragon2U, #88967140
same thing
If you can find THIS actuator, please let me know. I will buy one and repair the shifter mechanism I am replacing.

Picture
1. NOTE: Five pins
Only thing on actuator was stamped in ink, 11983, brought up nothing. Patent # were good and I know who invented this actuator, just not where to find one.
If the Solenoid has a number on it. You may be able to take it to Graingers and get it matched up. This of course is depending on the Switch making good Continuity at all times. But I have had good luck just using Graingers Solenoid Equal Listings across Manufacturers.
If I remember correctly WOWFACTR Had this same problem. He may have some quick reference to help find it for you.

Thanks, I have the shifter/actuator on the way, which solves my problem.
I will then have time to research the Shift Lock Control Actuator and maybe find the source.
Dicktator,
Is this the same switch you had me locate and push when my shifter was stuck in park while I was putting in the shift cable fix? Do these go bad too?
My SSR: UV SSR My other SS is an HHR SS "The RED ROCKET" "Tuned by CJ"
Briggs and Stratton?
Briggs and Stratton? Now Stratec. INC. made or sourced a bunch of the electrical controls on the SSR. They are how I found the lid actuator made by Hella.

Dicktator,
Is this the same switch you had me locate and push when my shifter was stuck in park while I was putting in the shift cable fix? Do these go bad too?
YES, IT WAS!! I guess they can go bad, mine did. This is not a usual problem, I would not worry about it.
It is part of the Shift Lock Control System. They want it in Park before you take key out, they want it in Park and Brake on when operating the Roof, etc.
What bothered me, is I had to buy the WHOLE shifter to get the actuator. And the actuator has two screws holding it in. There is no part number on the part, in the manual or on the exploded drawings. AND it is a Five Pin Connector.
We took it apart and there is another solenoid inside by the micro switch. Ed Borland did some testing and mine is BAD!
Yes it was the Shift Lock Control Actuator located on the Shift Console.
Had to remove seat, windjammer,waterfall, console, side panels to get to the shift actuator.
Had to buy the WHOLE shifter, not just the actuator.
COST $118.00 with Discount!
I took the two screws off the actuator, installed on my OLD shifter and BINGO! Back in business.
Then put everything back.

1. Have to remove a few things to get to the Shift Lock Control Actuator
2. The Shift Lock Control Actuator
3. Location of Shift Lock Control Actuator
4. Two screws to remove Shift Lock Control Actuator
5. All back together.
1. This is what you have to buy to get the Shift Lock Control Actuator.
2. It mounts here with two screws, see holes. I just removed the actuator and put in on my shifter.
3. Mounted, see wire harness.
4. Key Solenoid out, can not remove key.
5. Key Solenoid in, can remove key, trans must be in park to release key, that is what the Shift Lock Control Actuator does.
Thanks for the pics. i called mark, he said it would be a couple of. im hoping to get the part this coming week. Everything is ready to receive the replacement actuator. It was easier to remove than i thought. Pictures helped a lot!
My SSR: 04 UV, BOD 2-18-04, SN 5550, lots of polished billet, Superchips, K&N - Previous 03 and 05 owner

Check your brake switch for proper operation. Here are the pinouts of the connector, you could check for proper grounding and power, a text layout is below but I will also attach a wiring diagram for you. You can insure that the pins are getting proper power and grounding, if not, just follow the signal back to where it is getting power and isolate the issue.
Latch
F E D
A B C
A = BK Ground
B = Lt Gn/BK Switch supply voltage
C = YE Remote selector signal
D =- not used
E = Dk Gn/WH solenoid control voltage
F = PK IGN3 voltage
The "new" one from the junkyard might be bad. You can order just the solenoid from EBay for $60.
What state are you in, maybe I or someone else could assist?
As a last resort you could just pull off the solenoid and drive without it, just make sure to put it in Park before leaving it and starting it.

I agree, he always documents his work well to help others. On the other hand, my camera skills are lacking in a big way.
