Back Tailgate Window Can;t Go Down on 1983 Chevy Suburban C20?

[blackandgold51]

I got 1983 Chevy Suburban C20 with the tailgate that has a window that can't go down

Who came up with this design where when the window can't go down, the tailgate can't go dow by the way? smh

Time to climb in the back and open up the hatch. Might have to wind it down by hand (or drill)

Huh? , how?

Also, i know they have tailgates that you can wind by hand, can i convert from electric to handwind?

Unscrew the cable that goes to the motor (other side goes to the regulator). There will be a square shaft that protrudes from the cable. Insert that into a drill and slowly spin it to see if it starts going down. If not then of course reverse the drill. Then you can spin it as fast as you want.

And just an FYI, the 'handwind' is referred to as a manual window.

Ill try that, still don't know why someone would come up with the idea of making a tailgate with a window that, if the window can't go the the tailgate wont....smh

Very simple reason, so you don't shatter the window when you close it. Also with the window fully extended it has very little strength or support and could break when lowering the tailgate.

Also, do you hear the motor trying to spin or is there nothing? Common issue for the motor not working is the lockout switch on the driver’s side next to the latch on the inside (at least that’s where it is on the Blazer).

 

[frankin5]

Lockout only prevents going up with the gate open or lockout switch open.

There isnt a cable drive on a suburban, take the panel off and there are 4 bolts on the bottom of the window on the metal part. Take those bolts off and drop the window down, then open the tailgate.

I am also having trouble making my window power down.

What I was wondering is that Chevy should have made a tailgate where the tailgate split open left and right, and the window open upwards like an Excursion. Or something like that

But then again lack of knowledge or technology back then in the 1970s to early 90s

Well, you could get these in the 60's and 70's, so I don't think technology was the issue:

As we know, complexity of moving parts can cause issues over time, though...

Ha! I seriously want a 1970 Estate Wagon to restomod. Perfect fit for me. I would ideally like to find a solid body and frame, but not running.

Low AF and blown.

My '72 Chevelle Nomad wagon had the "dual action" tailgate/door option..
I don't have a picture of the rear of it unfortunately..
Every time I see pictures of that car,I wish I still had it--had a 454,a Rockwell divorced transfer case,and a TH350...you could put any transmission you wanted in it with the divorced transfer case..it actually rode and drive quite nicely too,better than the '69 K10 Suburban that donated the chassis for it..
