Hello,

I just bought an 87 K5 Blazer with the crank down back window. Needless to say..the back window doesnt go up or down. You can see the "parts" moving but nothing makes the window move up or down. Where could I get a part for this or a diagram to show how its supposed to work?

Also, the rear tailgate wont go down...does the window have to be down for that to work?

Thanks,
Austin

 

Check out the exploded view of the components in LMCTruck.com's catalog.

From the sounds of it, the key cylinder has broken and is not turning the drive on the regulator.

 

Alright will do. I ordered a catalog as well but Ill go look online and check it out.

Thanks.
