HOW TO: Add Power Sliding Rear Window 14-18 Silverado or Sierra K2xx

[04palass]

I have done a lot of research in preparation for this mod, and there are not any how to guides on this so I figured I would make one!

 

 

 

First things first is the parts list. Below is what is required for this mod. 

 

Window (includes regulator):  84819603

GM list is $735. I found mine new on Facebook Marketplace for $150 so do some shopping around or they can be found used on car-part.com for much less but make sure it includes the regulator.

 

 

Motor and mount assembly (they are sold together): 23490454

GM List is $89.13. Perhaps can be found used cheaper but not a bad price from GM. I got mine from Ebay.

 

 

Overhead Console with switch: I recommend finding this used because often junkyards leave the harness intact which you will need. I got mine on Ebay. Side benefit the Homelink is plug and play so if your truck didn't come with it like mine you now have it.

 

 

Rear Window Lower Garnish Molding (Main longer piece): 22817432

Right Rear Window Garnish Molding: 22817430

*These are not required if you are handy with a Dremel

 

Next is the harness and fuse tap I used. This is an aftermarket harness that I modified to extend the length I needed.

Once you have gathered your parts contact a local shop to install your window.

 

 

Next you will need to figure out your trim. There are 2 ways to do this. You can buy the trim from GM or just trim a little off your factory ones.

This is the route I took. Just line it up where is should fit, put some painters tape on mark it and with a carful hand just trim it and it looks just like stock.

 

 

 

 

Next you’ll need to mount your motor and regulator assembly. Below are some pics I found online of a factory truck.

 

 

 

 

 

Once that is all mounted up its time for wiring. Using the Universal Harness and factory switch is fairly easy. Here is a diagram. The GM switch is pinned out just like the aftermarket harness I linked.

 

 

 

The factory switch and pigtail should come with the overhead panel just cut off the connector and splice it in. I routed the grounds together and self-tapped them into the truck by the fuse box. The power is ran to the fuse box (with an inline fuse) and tapped into key on power. Depending on your truck you may or may not have some of the options used to tap into. Below is a link to a great website you can poke around and figure out what fuse works best for your truck.

Finally run 2 wires back to the motor. I ran mine through the headline and down the passenger rear trim.

 

 

 

 

Once everything is connected you should have a working power rear window!

Nice work.  I haven't used mine in the 7 years I've owned my truck.
